The 3 would be considered after expiration of the infectious picture.

The first thing is to treat the infection and for this we must remove all the osteosynthesis material, debride and give antibiotherapy. Fixation in this case is better external to avoid all the material around the affected area, so 4 is correct and 1 and 2 is not. The 3 would be considered after expiration of the infectious picture. TREATMENT - Suppressive antibiotic treatment: indicated in patients with Ciemy type C, it consists of prolonged oral antibiotic therapy for at least 6 months to "cool" the exacerbation of the clinical picture. - Curative treatment: includes a first surgery with aggressive tumor-like debridement of all affected tissues, profuse irrigation, stabilization with external fixator if stability is compromised, and eventual filling of the cavities with antibiotic-releasing substances. After prolonged periods of antibiotic therapy selected according to the antibiograms of the cultures, and once it is certain that the infection has been cured, special techniques for the reconstruction of the bone defect and to achieve adequate coverage of soft tissues should be considered. We are dealing with an infection associated with an implant (intramedullary nail) and pseudoarthrosis of the tibia fracture (absence of union after 11 months). The infection is understood by the clinical manifestations (suppuration, nonunion) and the history of diabetes and open fracture. Management overlaps with the management of chronic osteomyelitis. Isolated antibiotherapy (option 2) is indicated only in patients with severe comorbidity in whom surgical treatment would be more aggressive than continuing the disease. Nail dynamization associated with broad-spectrum antibiotherapy (option 1) is not indicated either, because (a) it has not demonstrated benefit in established pseudarthrosis and (b) we have the same issue as option 1, we do not eliminate biofilm. Option 3, discussed, would be considered only if there was no associated infection.

At 11 months he presents with atrophic pseudarthrosis of the tibia with suppuration in the wound area. What will be his best immediate therapeutic option?

Triple antibiotherapy (gram-positive, gram-negative and anaerobic) and cleaning of the surgical wound, removing the distal locks to promote bone consolidation.

Expectant attitude and antibiotic treatment with quinolones.

Autologous graft and growth factors (BMP 2 and 7) to stimulate the bone consolidation process, which is slowing.

Removal of the nail, debridement, placement of external fixator and antibiotherapy adjusted to culture results.

[Advanced bone graft combined with locking compression plate for the treatment of middle and distal tibia nonunion].

To explore methods of treating middle and distal tibia nonunion with the treatment of advanced bone graft combined with locking compression plate. From January 2011 to December 2012, 12 patients with middle and distal tibia nonunion were treated with advanced bone graft combined with locking compression plate. Among patients, there were 8 males and 4 females aged from 20 to 69 with an average of 47 years old. The time from first injuries to bone nonunion was from 9 months to 5 years, avergaed 19 months. Four cases were treated with external fixation, 6 cases were treated with plate fixation, 2 cases of 12 patients occurred broken of plate and nail. Eleven patients were non-infective bone nonunion and 1 patient was infective bone nonunion. Preoperative X-ray and CT showed all patients had sequestration and formation of ossified bone with different degrees. Operative time, blood loss, wound healing were observed, fracture healing time was evaluated by postoperative X-ray. Johner-Wruhs scoring standards was used to evaluate ankle joint function after operation at 10 months. Operative time ranged from 90 to 185 min with an average of (125.00±20.15) min; blood loss ranged from 225 to 750 ml with an average of (415.00±120.00) ml. All patients were followed up from 10 months to 2.5 years with an average of 1.5 years. Postoperative X-ray showed bone union was formed around fracture after operation at 4 months in all patients, 3 cases obtained bone healing within 6 months after operation, 9 cases obtained from 8 to 12 months. No infection, injury of nerve and vessles, and broken of plate and nail were ocurred. According to Johner-Wruhs scoring at 10 months after operation, 10 cases obtained excellent results, 1 good and 1 moderate. Advanced bone graft combined with locking compression plate, which can build fracture multi-point supporting based on full compression of bone nonunion to get effective fixation, is an effective method in treating middle and distal tibia nonunion.

[Effectiveness of limbs shortening and re-lengthening in treatment of tibial infectious bone defect and chronic osteomyelitis].

To evaluate the limbs shortening and re-lengthening in the treatment of tibial infectious bone defect and chronic osteomyelitis. Between January 2011 and April 2016, 19 cases of tibial infectious bone defect and chronic osteomyelitis were treated with the limbs shortening and re-lengthening technique. There were 13 males and 6 females, aged from 22 to 62 years (mean, 44 years). The causes of injury included traffic accident injury in 16 cases, crush injury in 1 case, and falling from height in 2 cases. One patient was infected after plate internal fixation of closed tibial fracture and 18 patients after external fixation of open tibial fractures (Gustilo type IIIB). The mean previous operation times was 3 times (range, 2-5 times). The time from injury to bone transport operation was 3-11 months (mean, 6.5 months). The bone defect length was 2.0-5.5 cm (mean, 4.3 cm) after debridement. After tibial shortening, limb peripheral blood supply should be checked after release of the tourniquet. Seven wounds were closed directly, 5 were repaired with adjacent skin flap, 5 were repaired with sural neurovascular flap, 1 was repaired with medial head of gastrocnemius muscle flap, and 1 underwent skin grafting. Single arm external fixator or ring type external fixator were used, and completely sawed off between 2 sets of external fixation screws at proximal and distal metaphysis of the tibia. Limb lengthening was performed after 1 week with the speed of 1 mm/d. All patients were followed up 10-36 months with an average of 14 months. Two cases delayed healing of the wound after operation, and the other wounds healed primarily. Natural healing of the opposite end of the bone were found in 18 cases, and 1 case had nonunion in the opposite end of the bone because of incomplete removal of lesion bone. There were 5 cases of slow growth of the callus, and healed smoothly by "accordion" technology and injecting red bone marrow in 4 cases, and by bone grafting and internal fixation in 1 case. The time of bone lengthening was 1-3 months, the prolongation index was 1.6-2.7 cm/month (2.20 cm/month). The bone healing time was 7-13 months (mean, 11.1 months). According to tibial stem diagnostic criteria Johner-Wruhs score, 9 cases were excellent, 8 cases were good, 2 cases were fair, with an excellent and good rate of 89.5%. Limbs shortening and re-lengthening is an effective method for the treatment of tibial infectious bone defect and chronic osteomyelitis, with the advantages of improving the immediate alignment of the osteotomy ends, significantly shortening the bone healing time of opposite ends of bone.

Tibia fracture is the most common long bone fracture. The fractures of tibia are commonly open fractures due to subcutaneous position of the tibia. The choice of technique for stabilization of open tibia fractures includes - External fixation, unreamed intra-medullary nails [URTN], Reamed intra-medullary nails, ORIF with Plating. To evaluate & compare the results of Unreamed Intra-Medullary Nail Versus Half Pin External Fixator in Grade III [A & B] Open tibia fractures. This prospective clinical study [Randomized chit box] was done on 50 patients presenting to our institute within 24 h of injury. Only those who were skeletally mature with open tibia fracture Grade IIIA & IIIB [Gustilo-Anderson] were included in this study. After initial management, radiological assessment was done. Following this adequate wound debridement, skeletal stabilization with either primary URTN or external fixator was done. Inspection and debridement were repeated at 48-h intervals until the wound was considered clean. 50 cases [25 each group] were compared in terms of - Final Alignment of the Fracture, Presence of Infection/Non-union/Mal-union, Hardware failure, Time to Bone Union, Number of Operative Procedures after index admission. Mean time to full weight bearing was 20.96 weeks in URTN group versus 24.8 weeks in Ex-fix group. 5 in URTN group required further surgery for non-union versus 11 patients in Ex-fix group. There were 6 significant pin track infection. Removal of nail was required in 1 case of deep infection. This study supports the use of the URTN over External fixator in the treatment of severe open tibia fractures.

Bone Crushing in Infected Pseudarthrosis - An Extraordinary Way to Treat Osteomyelitis Caused by Resistant Bacteria.

Osteomyelitis with multiresistant bacteria in non-union following fracture treated with osteosynthesis requires complete removal of infected sequestrum and dead bone. For consecutive bone defects, it is frequently necessary to bridge with a fixator external. The treatment is not only challenging due to reduced bone stock but also characterized by decreased bioavailability of antibiotics. We report a two-step-surgery approach to preserve the bone stock using autologous cancellous bone in a bacterial infected non-union for subsequently leg length reconstruction. The 24-year-old male patient from Belarus was admitted to our department with persistent wound secretion and subsequent osteomyelitis of the right femur 3 years after initial surgery, several revisions, and several different antibiotic therapies. Biopsy revealed methicillin-resistant and borderline oxacillin-resistant Staphylococcus aureus. Firstly, the Ilizarov ring fixator was removed and a vigorous debridement was performed by refreshing the pseudarthrosis, removing of sequestrum, and dead bone. Finally, an AO fixator external was applied for 10 weeks combined with appropriate antibiotic treatment followed by 5 weeks antibiotic-free window. The bone defect was stabilized by a long gamma trochanteric nail after removal of the AO fixateurexterne. A wide resection of the fragments was performed and the resected bone tissue was crushed and placed adjacent to the nail. Noteworthy, the biopsies of both re-section sides revealed same germs as detected in initial biopsies. Thus, antibiotics were administered for additional 3 months. Frequent radiographic and clinical controls showed a remodeling of the femur during a period of 3 years and no signs of infection. Subsequently, we restored leg length of 4 cm using a fully implantable motorized lengthening nail. In the end, the patient achieved full weight-bearing with unlimited range of motion in hip and knee. No further germ could be revealed in biopsies. In this case report, we used autologous bone from the infected side, crushed, and placed it adjacent to an intramedullary nail. Crushed bone tissue might improve bioavailability of antibiotics when dealing with multiresistant bacteria in non-union healed fracture side. Furthermore, this approach was able to provide new bone formation in a limb resulting in full weight-bearing.

Tibia Nonunion -- Treatment / Management -- Operative Treatments

Single-stage approach: This involves surgical debridement of all non-viable tissues and bone ends, multiple cultures to be taken from the nonunion site or canal reaming followed by revision open reduction and internal fixation or exchange nailing. Antibiotic administration is tailored to culture results and sensitivities [24] [25] . When open treatment is essential, autologous bone grafting has been recommended as an adjunct [16] . Staged approach: usually indicated for septic tibial nonunion. This involves steps to control infection followed by definitive surgery.

InternalMed_Harrison

As mentioned above, correlation between cultures of bone and those of wound swabs or wound punctures is poor. Antibiotic treatment should be based on bone culture. If no bone biopsy is performed, empirical therapy chosen in light of the most common infecting agents and the type of clinical syndrome should be given. Wound debridement combined with a 4to 6-week course of antibiotics has been shown to render amputation unnecessary in about two-thirds of patients. According to the 2012 Infectious Diseases Society of America Clinical Practice Guideline for the Diagnosis and Treatment of Diabetic Foot Infections, the following management strategies should be considered. If a foot ulcer is clinically infected, prompt empirical antimicrobial therapy may prevent progression to osteomyelitis. When the risk of methicillin-resistant S. aureus is considered high, an agent active against these strains (e.g., vancomycin) should be chosen. If the patient has not recently received antibiotics, the

Management of Large Bone Defects in Diaphyseal Fractures by Induced Membrane Formation by Masquelet's Technique.

Management of the large gap in long bone fractures is a challenging problem after compound injuries. A novel technique called as Masquelet's technique of "induced membrane formation", is used to bridge a gap of more than 5 cm using bone cement as a spacer in first stage and autologous cancellous bone graft to fill the gap in second stage. We present two different and difficult cases with bone defects after open injuries associated with long bone fractures in this paper. First case is a 50-year-old lady with grade IIIa open fracture right distal femur with intra-articular extension and bone loss. She underwent wound debriment, stabilization of the fracture with locking compression plate along with antibiotic cement spacer, which is removed latter and underwent bone grafting. Another is a 15-year-old boy with open grade IIIb fracture tibia and fibula (mid-distal third junction) of right leg, wound debridement and ankle spanning triangular external fixation was applied on same day and after two months, external fixation was removed due to florid infection and plaster of Paris was applied. Instead of the tedious and demanding treatment options like Ilizarov, a new technique described by Masquelet is used here. It uses bone cement as a spacer to fill the cavity to form pseudo-membrane around it and in the second stage autologous cancellous bone graft fills the gap of even more than 5 cm, to achieve union. The membrane also secretes vascular and osteo-inductive factors to stimulate bone regeneration and also prevents resorption of the bone graft and achieves early fracture healing avoiding tedious options like bone transport in external fixator. By this two staged technique, union occurred clinically and radiologically in these two cases.

[Infected tibial shaft pseudarthroses, treatment and results (author's transl)].

In a follow up study of 47 patients with infected pseudarthrosis of tibia therapy and results are declared. The most important matter in therapy is the osteosyntesis with compression of the pseudarthrosis. In the majority of cases externe stabilisation is used; seldom compression plate or medullary nailing is indicated. Such cases require much experience in the therapy of bone infection, although if the stabilisation with the fibula is tryed. Flush drainage, suction drainage, antibiotic therapy and cancellous bone grafting are necessary for localisation and decreasing of infection and for induction and acceleration of bone union. In some cases amutation can't be prevented. With correct judgement and consequent treatment in the majority of cases bone union will be obtained.

Masquelet Technique and Proximal Tibial Autograft Utilizing Avitus® Bone Harvester for Severely Comminuted Open Distal Radius Fracture with Extensive Bone Loss: A Case Report.

Distal radius fractures are one of the most common fractures in the United States. Treatment usually involves internal fixation using a volar Henry approach with placement of a volar locking plate. Optimal treatment becomes less apparent when significant bone loss occurs. No case of an open distal radius fracture treated using a staged Masquelet technique involving proximal tibial autograft is available in the literature. Herein, we describe and discuss a case report of a novel technique to treat a large (5 cm) bone defect for an open distal radius fracture. A 59-year-old man suffered an open, comminuted, and intra-articular distal radius fracture with 5 cm of bone loss. He was treated using a staged Masquelet technique with incorporation of ipsilateral proximal tibial autograft with a bone harvester to obtain cancellous autograft and bone marrow graft. The patient initially underwent emergent I and D, acute carpal tunnel release, and internal and external fixation. A 5 cm bone void was filled with antibiotic cement. Four weeks later, the antibiotic cement was removed, cancellous bone graft and marrow were harvested from the proximal tibia, and the graft was placed within the prior bone void. Fracture site healing was confirmed radiographically and with computer-tomography imaging 3 months later. The patient has demonstrated excellent results 1 year post-operative with 60° of wrist flexion, 40° of wrist extension with mild pain, and full finger range of motion with radiographic union. Internal fixation with placement of a volar locking plate remains the mainstay of treatment for distal radial fractures. However, in more comminuted fractures with bone loss, treatment becomes more challenging. We have presented a unique case utilizing a staged Masquelet technique with incorporation of a proximal tibial autograft to educate readers on an alternative option and technique for autograft donor sites in these more complicated fractures.

[Surgical treatment of diaphyseal tibial fractures. Choice of procedure and results of treatment of 187 fractures].

From 1988 to 1990 a total of 187 fractures of the tibia (92 compound, 95 closed fractures) were treated with a primary osteosynthesis. In 102 fractures an external fixation was performed, 85 internal fixations were divided into 58 intramedullary nails and 27 plates. In a follow-up study the fracture healing was analysed, 90% of the patients were examined about 18 months after the accident. The mean healing time was between 12 weeks (internal fixation) and 16 weeks (external fixateur). After primary Fixateur externe 54 were treated by secondary internal fixation, intramedullary nailing was the method of choice. Contamination rate of the tibia, taken by an intraoperative wound swab before nailing was 30%. Infection occurred in 3.2%, non union and refractures in 1.5% and 1%. Over all 80% excellent and good results were found after consolidation. 10% fair and 10% bad results including three amputations after III degrees compound fractures and three death after polytrauma.

A Gustilo Type 3B Open Tibial Fracture Treated with a Proximal Flexor Hallucis Longus Flap: A Case Report.

In the treatment of Gustilo Type 3B open tibial fractures, it is important to perform soft tissue reconstruction and bone reconstruction simultaneously. Gastrocnemius muscle and soleus muscle flaps are generally used as rotational flaps for the tibia. The distal third of the tibia can often not be covered with the gastrocnemius muscle and soleus muscle flaps. Treatment distal to the distal third of the tibia is difficult because fewer flap options are available. In the present report, we describe our experience with a Gustilo Type 3B open tibial fracture treated by gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure. The participant was a 17-year-old male who injured his left tibia in a motorcycle traffic accident. Physical examination revealed a wound of 13 cm × 7 cm extending from the medial lower leg to the posterior aspect, with extensive skin loss. There was no nerve or vascular injury. The tibia was exposed, with detachment of the periosteum. The radiograph revealed a tibial shaft fracture. The AO/OTA classification was 42-A3.3, and it was classified as a Gustilo-Anderson Type 3B fracture. Gastrocnemius muscle and soleus muscle flaps were lifted in the area of the soft-tissue defect and then, placed over the tibia. Despite this, the distal portion of the tibia remained uncovered. Therefore, a flexor hallucis longus flap was lifted and placed over the distal portion of the tibia. On day 7 after the injury, the external fixation device was removed and the tibial shaft was fixated with two Ender nails (4.5 mm in diameter). The clinical course was satisfactory, and the skin graft and flap were successful. Bone union was achieved without infection, and the resulting range of motion was normal. For the treatment of Gustilo-Anderson Type 3B open tibial fractures, early treatment of the soft-tissue defect is vital. We surgically treated a Gustilo-Anderson Type 3B open tibial fracture with gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure. In the event of a soft-tissue defect in the distal third of the tibia, the use of a proximally based flexor hallucis longus flap is an effective surgical approach.

Prevention of infection in open fractures: Where are the pendulums now?

Soft tissue management and fracture fixation including initial external fixation in Gustilo-Anderson type II and type III open fractures are cornerstones in the treatment but details on timing and type of wound closure, irrigation and debridement, systemic and local antibiotics, antimicrobial-coated implants and the use of Bone Morphogenetic Protein-2 remain controversial. This article looks at current clinical evidence of these items for the management of open fractures. Timing of debridement and wound closure remains critical. Early debridement by an experienced team within 24 h seems adequate while gross contamination, a devascularized limb, a multi-injured patient and compartment syndrome require immediate surgical intervention. Wound closure during the first surgery was shown to result in reduced rates for infections and nonunion. If soft-tissue reconstruction is needed, it should be performed within the first 7 days. Regarding types of irrigation fluid, antiseptic and antibacterial solutions did not prove to be superior to saline. High pressure irrigation has not been demonstrated to be beneficial whereas antibiotic administration as soon as possible has been proven to be favorable. Administration of more than 72 h was not superior to shorter systemic antibiotic intervals. For Gustilo-Anderson type I and II, broad spectrum antibiotic therapy is reasonable. Additional aminoglycosides for broader coverage are recommended in Gustilo-Anderson type III fractures. There is newer literature on the beneficial effects of the use of local antibiotics, e.g. by antibiotic beads. Coating of internal fixation devices is a modern approach to improve infection prophylaxis and gentamicin-coated implants have been demonstrated to be safe in clinical application. Vacuum assisted closure (VAC) could not evidence negative pressure wound therapy to reduce infection risk, improve self-rated disability or quality of life in open fractures, however, enhance treatment costs. Recombinant human bone morphogenetic proteins (rhBMP)-2 showed promising data in Gustilo-Anderson type III open tibial shaft fractures with lower rates of invasive secondary procedures. In conclusion, there is evidence for thorough debridement and irrigation with saline, early soft tissue coverage and the use of systemic and local antibiotics. Except for a short-term soft tissue coverage VAC seems not to be beneficial and rhBMP-2 is an additional tool in Gustilo-Anderson type III open fractures.

Salvage procedures in lower-extremity trauma in a child with hereditary motor and sensory neuropathy type I: a case report.

Fractures of the lower extremity are a common type of childhood injury and many can be treated without surgery. Dislocated and open fractures are an indication for fracture stabilization via either intramedullary nailing or, in the case of complicated fractures, external fixation. But if complications are likely because of diseases and disabilities (for example, a neuropathy) that can complicate the post-operative procedure and rehabilitation, what options does one have? We report a nine-year-old Caucasian girl who had hereditary motor and sensory neuropathy type I and who was admitted with a grade I open tibia fracture after a fall from a small height. Plain radiographs showed a dislocated tibia and fibula fracture. An open reduction with internal fixation with a compression plate osteosynthesis was performed, and soft tissue debridement combined with an external fixateur was undertaken. Three months later, she was re-admitted with localized swelling and signs of a local soft tissue infection in the middle of her tibia. Plain radiographs showed a non-union of the tibia fracture, and microbiological analysis confirmed a wound infection with cefuroxime-sensitive Staphylococcus aureus. Because of the non-union, the osteosynthesis was replaced with an Ilizarov external fixateur, and appropriate antibiotic therapy was initiated. Four months after the initial accident, the fracture was consolidated and we removed the external fixateur. If there is a pre-existing neuropathy and if disease makes it difficult for a child to follow all post-operative instructions, salvage procedures should be kept in mind in case of complications. There are multiple therapeutic options, including osteosynthesis, intramedullary nailing systems, cast therapy, or an external fixateur like the Ilizarov or Taylor spatial frame system. The initial use of an external fixateur such as an Ilizarov or Taylor spatial frame in patients with pre-existing neuropathies should be kept in mind as a possible treatment option in complicated fractures, especially in a child with pre-existing neurological or endocrine pathologies.

Recombinant human BMP-2 for the treatment of open tibial fractures.

Recombinant human bone morphogenetic protein-2 (rhBMP-2) improves healing of open tibial fractures treated with intramedullary nail fixation. However, routine use has not occurred. The purposes of the current study were to provide a systematic review of the literature using rhBMP-2 in the treatment of acute open tibial fractures treated with intramedullary nail fixation and to provide a meta-analysis of the randomized, controlled trials. Multiple databases, reference lists of relative articles, and main orthopedic journals were searched. The basic information and major results were compared. Four studies with a total of 609 patients were included.The secondary intervention rate in the standard-of-care (SOC) group was significantly higher than in the rhBMP-2 combined with absorbable collagen sponge (rhBMP-2/ACS) group (27.1% vs 17.5%, respectively; P<.01). The treatment failure rate in the SOC group was significantly higher (34.3% vs. 21.4%, respectively; P<.01). No significant differences were found in infection rate, hardware failure rate, fracture healing rate at 20 weeks, and postoperative pain level. For patients treated with reamed intramedullary nail fixation, only the treatment failure rate in the SOC group was significantly higher (21.5% vs 14.2%, respectively; P=.02); no other significant difference was observed. Adding rhBMP-2 to the treatment of Gustilo-Anderson grade IIIA and B open tibial fractures led to net savings of approximately $6000 per case.Recombinant human bone morphogenetic protein-2 added to intramedullary nail fixation of open tibial fractures could reduce the frequency of secondary interventions and total health care costs. For reamed patients, adding rhBMP-2 reduced treatment failure. This analysis supports the clinical efficacy of rhBMP-2/ACS for the treatment of these severe fractures.

[Treatment of the postoperative infection of limbs fracture after internal fixation with vacuum sealing drainage (VSD) combined with continual irrigation].

To explore the clinical effects of VSD combined with continual irrigation in treating the infection of limbs fracture after internal fixation. From March 2010 to June 2015, 10 patients with infection of limbs fracture after internal fixation were treated with VSD combined with continual irrigation. There were 7 males and 3 females, aged from 11 to 58 years with an average of 34.4 years. Course of disease was from 1 to 8 months with an average of 4.8 months. Postoperative infection occurred in fractures of ulna and radius of 4 cases, tibiofibular fractures of 3 cases, calcaneal fractures of 2 cases, femoral fractures of 1 case. Eight infections were open fracture and 2 infections were close fracture. In additon to above treatment, antibiotics, dressing changing or skingrafting were used in the patients. Informations of wound surface healing, change dressings, original infection focus were observed. All infections got control, the wound healing after change dressings or skingrafting, and no complications such as osteomyelitis were found. The mean treatment time was 38.4 days(ranged, 29 to 45 days) and replacement times was 2.2 times(ranged, 1 to 4 times). All patients were followed up, no recurrent infections were found at 1 year after fracture healing. VSD combined with continual irrigation can effectively decrease the incidence of complications and promote the wound growth, healing and considerably shorten the healing time. It is an effective method for the treatment of infection of limbs fracture after internal fixation.

Outcome of Locked Compressive Nailing in Aseptic Tibial Diaphyseal Nonunions without Bone Defect.

Treatment of tibial diaphyseal nonunions are rather difficult. Plate-screw, intramedullary nailing and external fixation are the methods used for treatment. The aim of this study is to evaluate the treatment results of aseptic diaphyseal nonunions following tibia fractures by intramedullary compressive tibia nailing (IMCN) with or without bone graft. Twenty eight patients who had aseptic tibial nonunion without bone defects operated between 2005 and 2015 were included in the study. The mean age of our patients was 36.4 years (range 20-56 years). There were 22 males and 6 females. Fifteen of the patients exhibited hypertrophic nonunion and thirteen exhibited atrophic nonunion. The average time between fracture occurrence and presentation to our department was 1.6 years (range 1-20 years). All patients underwent fibular osteotomy by removal of a 2 cm bone block from the middle one-third of the fibulas. In all cases, IMCN was applied following the reaming procedure, then maximum bone contacts were achieved manually between proximal and distal bone fragments afterward, and dynamic compressive fixation with 1 mm of compression was performed by a single rotation of the compression screw at the top of the nail. Direct X-ray images were assessed according to the Rust criteria, and functional outcomes were assessed according to the Johner-Wrush criteria. Finite-element analysis was performed for 1 mm of compression. For statistical analysis, Fisher's exact test, Pearson's Chi-square test, and Mann-Whitney U-test were used. Union was achieved in all patients. Radiological union was obtained at an average of 15.5 ± 1.86 weeks. Functional results were found to be good or excellent in 25 (89.2%) patients and average or poor in 3 (10.8%) patients. One patient developed skin necrosis at the wound site, which was treated with rotational flap and skin graft. None of the patients developed implant failure, thromboembolism, deep-vein thrombosis, or infection. The use of compressive intramedullary nailing with or without bone graft is an effective method for the treatment of tibial nonunion.

[Plate fixation and open wound treatment in infected intramedullar nails].

In treating patients who present with an extensive non-union due to infected intramedullary nail, bone healing can be achieved within a few weeks through a policy of active management. Following excision of the infected tissue and thorough irrigation, the fracture site is stabilized by a plate fixation and a packet with cancellous bone. The wound overlying the bone is left open to granulate. No complications were observed during the course of healing in 7 cases (5 tibia, 2 femur) managed this way. The method is based on classical principles of orthopedics and the treatment of infection. Such has been its impressive success, that it would seem to warrant not only close attention but also strong recommendation.

Treatment of open tibial fracture with bone defect caused by high velocity missiles: a case report.

Tibia fracture caused by high velocity missiles is mostly comminuted and followed by bone defect which makes their healing process extremely difficult and prone to numerous complications. A 34-year-old male was wounded at close range by a semi-automatic gun missile. He was wounded in the distal area of the left tibia and suffered a massive defect of the bone and soft tissue. After the primary treatment of the wound, the fracture was stabilized with an external fixator type Mitkovic, with convergent orientation of the pins. The wound in the medial region of the tibia was closed with the secondary stitch, whereas the wound in the lateral area was closed with the skin transplant after Thiersch. Due to massive bone defect in the area of the rifle-missile wound six months after injury, a medical team placed a reconstructive external skeletal fixator type Mitkovic and performed corticotomy in the proximal metaphyseal area of the tibia. By the method of bone transport (distractive osteogenesis), the bone defect of the tibia was replaced. After the fracture healing seven months from the secondary surgery, the fixator was removed and the patient was referred to physical therapy. Surgical treatment of wounds, external fixation, performing necessary debridement, adequate antibiotic treatment and soft and bone tissue reconstruction are essential in achieving good results in patients with the open tibial fracture with bone defect caused by high velocity missiles. Reconstruction of bone defect can be successfully treated by reconstructive external fixator Mitkovic.

Treatment options for aseptic tibial diaphyseal nonunion: A review of selected studies.

In aseptic tibial diaphyseal nonunions after failed conservative treatment, the recommended treatment is a reamed intramedullary (IM) nail.Typically, when an aseptic tibial nonunion previously treated with an IM nail is found, it is advisable to change the previous IM nail for a larger diameter reamed and locked IM nail (the rate of success of renailing is around 90%).A second change after an IM nail failure is also a good option, especially if bone healing has progressed after the first change.Fibular osteotomy is not routinely advised; it is only recommended when it interferes with the nonunion site.In delayed unions before 24 weeks, IM nail dynamization can be performed as a less invasive option before deciding on a nail change.If there is a bone defect, a bone graft must be recommended, with the gold standard being the autologous iliac crest bone graft (AICBG).A reamer-irrigator-aspirator (RIA) system might also obtain a bone autograft that is comparable to AICBG.Although the size of the bone defect suitable to perform bone transport techniques is a controversial issue, we believe that such techniques can be considered in bone defects > 3 cm.Non-invasive therapies and biologic therapies could be applied in isolation for patients with high surgical risk, or could be used as adjuvants to the aforementioned surgical treatments.

Elastic Stable Intramedullary Nailing of Pediatric Tibial Fractures.

Most pediatric tibial shaft fractures (75%)<sup1</sup can be treated nonoperatively; however, unstable and open fractures require surgical intervention. Titanium elastic nails have become a popular technique for fixation of pediatric tibial shaft fractures. They act as internal splints that impart relative stability to the fracture, promoting callus formation at the fracture site<sup2</sup. After the patient is placed in the supine position, the proximal tibial physis is marked using fluoroscopy. An anteromedial and anterolateral incision are made distal to the physis. Entry holes are created in the proximal part of the tibia, and appropriately sized titanium nails are introduced into the bone. Nail size should be 40% of the width of the canal, yielding 80% canal fill when 2 nails are used. The nails are prebent into a gentle C-shape to increase cortical contact at the apex so that 3-point fixation is achieved. The nails are passed to the fracture site, and the fracture is then reduced. The nails are then passed across the fracture site and stopped proximal to the distal tibial physis. The nails are then cut and tamped distally until there is just a short portion of nail left out of the proximal part of the tibia so that the nails can be removed once the fracture is healed. The wounds are then closed, and postoperative immobilization is applied. Many pediatric tibial shaft fractures can be treated with closed reduction and cast immobilization. Open fractures, or fractures that fail nonoperative management, can be treated with external fixation, open reduction and internal fixation (ORIF), or intramedullary stabilization<sup3</sup. Anatomic reduction and fracture compression can be achieved with ORIF; however, a drawback to this technique is the lack of soft-tissue coverage in the diaphyseal area of the tibia, which can lead to infection and wound-healing problems<sup4</sup. External fixation has traditionally been the technique of choice for open tibial fractures; however, with the ability to use flexible tibial nails in both open and closed tibial fractures, external fixation is now reserved for open fractures with large soft-tissue defects or in fractures with segmental bone loss. Intramedullary flexible nailing can be used in both open and closed tibial fractures, provides excellent fracture fixation, and utilizes incisions that are more cosmetically appealing to patients<sup5,6</sup. Outcomes following flexible nailing for pediatric tibial fractures are excellent. In a study of 19 patients undergoing flexible nailing for tibial shaft fractures, 18 had excellent or satisfactory results<sup7</sup. Compared with patients who had external fixation, those treated with flexible nails had less pain, shorter time to union, and better functional outcomes<sup2</sup. Compared with patients treated with ORIF, those who underwent flexible intramedullary nailing spent less time in the operating room and had lower rates of wound complications<sup4</sup. In the immediate postoperative period, clinicians should be aware of the risk of compartment syndrome, particularly in patients with high-energy injuries, older patients (>14 years old), and heavier patients (>50 kg)<sup8</sup. There is also an increased risk of soft-tissue irritation and fracture malunion in heavier patients treated with flexible nails<sup9,10</sup. Nail size should be 80% of the canal diameter (e.g., two 4.0-mm nails should be chosen for a canal that measures 10 mm).Nails should be properly contoured to avoid corticotomy of the far cortex during insertion; apex of the bend should be positioned at the level of the fracture.During insertion, leave room to advance nails further after they are cut proximally.Do not bury the proximal nail tips beneath the cortex as extraction will be difficult.Ensure that the ends of the nails are not lying up against the proximal tibial physis as this may cause premature growth arrest.

Uncoated vs. Antibiotic-Coated Tibia Nail in Open Diaphyseal Tibial Fracture (42 according to AO Classification): A Single Center Experience.

Implant-associated infections remain one of the main problems in the treatment of open tibia fractures. The role of systemic antibiotic prophylaxis is now agreed and accepted; nevertheless, recent literature also seems to emphasize the importance of local antibiotic therapy at the fracture site. Several therapeutic strategies have been proposed to overcome this new need. Antibiotic-coated nails play crucial role in this, allowing both infection prevention and favoring the fracture stabilization. We describe the outcome of patients with open diaphyseal tibia fracture treated either with a standard uncoated nail or a gentamicin-coated nail from January 2016 to December 2018 at our second level emergency-urgency department. Primary outcomes were infection rate and bone union rate. Other outcomes reported are reoperation rate, time between injury and nailing, and safety of antibiotic nail. Numerical variables were tabulated using mean, standard deviation, minimum, maximum, and number of observations. Categorical variables were tabulated using number of observations. 23 patients treated with uncoated nail and 23 patients treated with antibiotic-coated tibia nail were included in the study and were evaluated for a minimum follow-up of 18 months. Among the 46 patients, 9 were Gustilo-Anderson type I, 21 type II, and 16 type III open fracture. Regarding the bone healing rate at 12 months, 16 fractures in the first group and 18 in the second were completely healed. 4 infections were found in the first group (3 superficial surgical site infection and 1 osteomyelitis) and 3 superficial infections in the second one. No adverse events have been recorded with antibiotic-coated nails. In this unicentric retrospective study observed no deep wound infections and good fracture healing in the use of antibiotic-coated nails. Antibiotic nails have been shown to play a role in the treatment of fractures in critically ill patients with severe soft tissue damage.

Open fracture

An open fracture, also called a compound fracture, is a type of bone fracture in orthopedics that is frequently caused by high energy trauma. It is a bone fracture associated with a break in the skin continuity which can cause complications such as infection, malunion, and nonunion. Gustilo open fracture classification is the most commonly used method to classify open fractures, to guide treatment and to predict clinical outcomes. Advanced trauma life support is the first line of action in dealing with open fractures and to rule out other life-threatening condition in cases of trauma. Cephalosporins are generally the first line of antibiotics. The antibiotics are continued for 24 hours to minimize the risk of infections. Therapeutic irrigation, wound debridement, early wound closure and bone fixation are the main management of open fractures. All these actions aimed to reduce the risk of infections. Causes

Extraction of Broken Tibial Interlock Nail with a Retrograde Hooked Guide Wire: A Novel Surgical Technique.

Removal of a distal piece of a broken nail often possesses a technical challenge. Several methods have been described in the past to extract a distal piece by using specialized instruments like such as hooks, olive wires, and talwalkar radial square nail etc. It is difficult to extract a distal piece from a proximal incision site and often fracture or the nonunion site has to be opened. In this article, we describe a novel technique to extract a distal piece of broken intramedullary tibia nail by retrograde manner using a guide wire with a "'U"' shaped bend at its distal end to hook the tip of a distal piece of broken nail and help in extraction. A 43- year-s old male presented with complain of pain in left leg since 3 months. Patient had sustained left- sided compound Grade 2 tibia shaft fracture in a road traffic accident 4 years back. He was operated with tibia interlock nail followed by skin grafting for wound coverage in a different facility. On clinical examination: There was tenderness around distal tibia, no swelling, no coronal or sagittal plane fracture mobility, and no crepitus or loss of transmitted movements which suggested fracture union clinically. Radiographs confirmed complete union of tibia shaft fracture with hypertrophic nonunion of distal fibula with broken intramedullary nail IMN at the level of proximal most screw hole of distal locking holes with both distal locking screws broken. As fracture was united, we planned for removal of broken nail without opening fracture site. For extraction for distal tibial broken nail part, we used this new Retrograde Hooked Guide Wire technique. It is a simple, cost effective, minimally invasive procedure with minimal blood loss and decrease time of surgery that can be used before attempting more invasive extraction methods and hence should be included in standard procedures for extraction.

Antibiotic artificial bone implantation and external fixation for the treatment of infection after intramedullary nail fixation: a retrospective study of 33 cases.

To explore the clinical effect of antibiotic artificial bone implantation and external fixation in the treatment of infection after intramedullary nail fixation. We retrospectively reviewed the clinical data of patients with infection after intramedullary nail fixation treated from March 2010 to August 2020. There were 27 males and 6 female, aged from 12 to 67 years (average 42.27 years), 18 cases on the left side and 15 cases on the right side. Among them, 20 cases were open fractures with initial injury and 13 cases were closed fractures. All patients were treated with intramedullary nail removal, local debridement, antibiotic artificial bone implantation and external fixation. Because of bone defects, 19 patients underwent secondary autologous cancellous bone grafting after infection control. Postoperative wound healing, related inflammatory indicators, fixation time, and bone healing time were recorded and followed up. The 33 patients were followed up with period of 10 ~ 98 months (average 62.7 months). One patients failed to control the infection effectively after treatment, so received antibiotics artificial bone implantation again. Two patients also received antibiotic artificial bone implants again due to the recurrence of the infection. After treatment, infection was controlled and the fracture healed well. One patient received vacuum sealing drainage (VSD) due to persistent postoperative exudation, and five patients were also cured successfully after continuous dressing. Two patients had sinus tract after surgery, and the wound was cured by continuous dressing change. Nineteen patients received autogenous iliac bone grafts for healing due to bone defects ranging from 3 to 6.5 cm (average 4.15 cm) after infection control. The external fixation time of 33 patients ranged from 4 to 16 months (average 7.79 months), the bone healing time ranged from 4 to 13 months (average 6.67 months), and the related inflammatory indexes returned to normal within 2-8 weeks (average 4.48 weeks). Antibiotic artificial bone implantation and external fixation is an effective method for the treatment of infection after intramedullary nail fixation.

Distraction over nail using circular external fixation for septic pseudarthrosis of the tibia.

We present a report of nine patients (eight women and one man; mean age 37 years) from 2010 to 2012 with septic pseudarthrosis of the tibia treated with bone transport over an intramedullary nail using a circular external fixator. The mean follow-up was 15 months (range: 10-21 months). A two stage approach was used. At the first stage, removal of the primary osteosynthesis and extensive bone debridement to healthy, bleeding bone margins was performed. The bone defect was packed with antibiotic loaded cement beads, and stabilization of the tibia was done with a unilateral external fixator or with a long leg posterior splint. The mean size of bone defect was 4 cm (range: 3.5-5.5 cm). At the second stage, two consecutive negative wound cultures and normal values of blood cell count, C-reactive protein (CRP), and estimated sedimentation rate (ESR) were obtained. Then we reamed and locked the intramedullary nailing of the tibia, applied a circular external fixator, and performed percutaneous corticotomy of the tibia opposite the site of the bone defect. Bone distraction over the nail was initiated at the eighth postoperative day at a rate of 1 mm/day. At the last follow-up, union was achieved in all cases without recurrence of bone infection. All patients experienced excellent (n=3) or good (n=6) knee and ankle function, as well as complete return to their daily activities. Two patients experienced pin-tract infection, and one patient experienced anterior knee pain at the entry point of the nail.

[Treatment of uninfected pseudarthroses of the lower extremity near the joint using the Küntscher medullary nail].

The Küntscher nail has proved successful in the treatment of non-unions of the median third of the femur and lower leg after opening of the medullary cavity; in fact, this method is described in literature as the method of choice. It is based on the assumption that a sufficiently dimensioned intramedullary Küntscher nail together with the biological stimulative action of the bone meal, will result in a rapid osseous bridging of the non-union. This method has been successfully used in 128 cases even in non-unions which were close to the joint. Healing occurred in 92% of the cases. In about 11 cases it became necessary to perform a secondary operation. The high rate of infection, amounting to 12.4%, is relatively low compared with the very high rate of infective relapses following the first operation to achieve healing of the bone fractures.

Tibia Nonunion -- Treatment / Management -- The following are details of operative treatment options and adjuncts reported in the literature:

Locking compression plates: It is indicated for managing nonunion of the metaphyseal diaphyseal junction fractures, where the outcomes of exchange nailing would be doubtful. The procedure is performed along with bone grafting and without the removal of the underlying nail by gaining unicortical purchase fixation with locking head screws. It has been shown to have predictable good results [32] [33] [32] . External fixation : Considered in complex nonunions (e.g., when internal fixation is not possible or not recommended due to infection, substantial deformity, and/or bone loss [12] [34] [12] .

Treatment of fracture-related infection of the lower extremity with antibiotic-eluting ceramic bone substitutes: case series of 35 patients and literature review.

The current treatment concepts of fracture-related infection (FRI) [Consensus Conference (Anti-Infection Task Force (AITF)) on the definition of acute or chronic osteomyelitis (cOM)] are associated with unsolved challenges and problems, underlining the need for ongoing medical research. Literature review of treatments for FRI and description of own cases. We could include eight papers with 394 patients reporting treatments and outcome in FRI. The infection was resolved in 92.9% (mean) of all treatments. The mean follow-up was 25 months with a persistent non-union in 7% of the patients. We diagnosed 35 (19f/16m; 56.4 ± 18.6 years) patients with bone infections anatomically allocated to the proximal and distal femur (12×), the pelvis (2×), distal tibia (3×), tibial diaphysis (11×), the ankle joint (4×) and calcaneus (3×). These 35 patients were treated (1) with surgical debridement; (2) with antibiotic-eluting ceramic bone substitutes; (3) bone stabilization (including nail fixation, arthrodesis nails, plates, or external ring fixation), (4) optionally negative pressure wound therapy (NPWT) and (5) optionally soft tissue closure with local or free flaps. The mean follow-up time was 14.9 ± 10.6 months (min/max: 2/40 month). The overall recurrence rate is low (8.5%, 3/35). Prolonged wound secretion was observed in six cases (17.1%, 6/35). The overall number of surgeries was a median of 2.5. The results in the literature and in our case series are explicitly promising regarding the treatment of posttraumatic fracture-related infection.

Recombinant human bone morphogenetic protein-2: a randomized trial in open tibial fractures treated with reamed nail fixation.

Recombinant human bone morphogenetic protein-2 (rhBMP-2) improves healing of open tibial fractures treated with unreamed intramedullary nail fixation. We evaluated the use of rhBMP-2 in the treatment of acute open tibial fractures treated with reamed intramedullary nail fixation. Patients were randomly assigned (1:1) to receive the standard of care consisting of intramedullary nail fixation and routine soft-tissue management (the SOC group) or the standard of care plus an absorbable collagen sponge implant containing 1.5 mg/mL of rhBMP-2 (total, 12.0 mg) (the rhBMP-2/ACS group). Randomization was stratified by fracture severity. The absorbable collagen sponge was placed over the fracture at wound closure. The primary efficacy end point was the proportion of subjects with a healed fracture as demonstrated by radiographic and clinical assessment thirteen and twenty weeks after definitive wound closure. Two hundred and seventy-seven patients were randomized and were the subjects of the intent-to-treat analysis. Thirteen percent of the fractures were Gustilo-Anderson Type IIIB. The proportions of patients with fracture-healing were 60% and 48% at week 13 (p = 0.0541) and 68% and 67% at week 20 in the rhBMP-2/ACS and SOC groups, respectively. Twelve percent of the subjects underwent secondary procedures in each group; more invasive procedures (e.g., exchange nailing) accounted for 30% of the procedures in the rhBMP-2/ACS group and 57% in the SOC group (p = 0.1271). Infection was seen in twenty-seven (19%) of the patients in the rhBMP-2/ACS group and fifteen (11%) in the SOC group (p = 0.0645; difference in infection risk = 0.09 [95% confidence interval, 0.0 to 0.17]). The adverse event incidence was otherwise similar between the treatment groups. The healing of open tibial fractures treated with reamed intramedullary nail fixation was not significantly accelerated by the addition of an absorbable collagen sponge containing rhBMP-2.

[Effectiveness analysis of induced membrane technique in the treatment of infectious bone defect].

To evaluate the effectiveness of induced membrane technique in the treatment of infectious bone defect. Thirty-six patients (37 bone lesions) with infectious bone defects were treated with induced membrane technique between January 2011 and June 2014. There were 28 males and 8 females with an average age of 36 years (range, 20-68 years). All bone defects were post-traumatic infectious bone defect. The bone defect was located at the tibia and fibula in 24 cases (25 bone lesions), at femurs in 6 cases (6 bone lesions), at ulnas and radii in 2 cases (2 bone lesions), at calcanei in 3 cases (3 bone lesions), and at clavicle in 1 case (1 bone lesion). The average time between onset and the treatment of induced membrane technique was 6.2 months (range, 0.5-36.0 months); 15 patients were acute infections (disease duration was less than 3 months). At the first stage, after the removal of internal fixator (applicable for the patients who had internal fixation), complete debridement of infection necrotic bone tissue and surrounding soft tissue was performed and the bone defects were filled with antibiotic-impregnated cement spacers. If the bone was unstable after debridement, external fixator or plaster could be used for stabilization. Patients received sensitive antibiotics postoperatively. At the second stage (usually 6-8 weeks later), the cement spacer were removed, with preservation of the induced membrane formed by the spacer, and filled the bone defect with autologous iliac bone graft within the membrane. The hospitalization time after debridement was 17-30 days (mean, 22.2 days), and the hospitalization time after the second stage was 7-14 days (mean, 10 days). All the flaps healed uneventfully in 16 cases treated with local flap transposition or free flap grafting after debridement. One patient of femur fracture received Ilizarov treatment after recurrence of infection at 11 months after operation; 1 patient of distal femoral fracture received amputation after recurrence of infection at 1 month after operation; 1 patient of distal end of tibia and fibula fractures received ankle arthrodesis after repeated debridements due to the recurrence of infection; 1 patient of tibia and fibula fractures lost to follow-up. The other 32 patients (33 bone lesions) were followed up 1-5 years (mean, 2 years) without infection recurrence, and the infection control rate was 91.7% (33/36). All the patients had bony union, and the healing time was 4-12 months (mean, 7.5 months); no refracture occurred. One patient of femur bone defect had a lateral angulation of 15° and leg discrepancy of 1.5 cm. Superficial pin infection was observed in 7 cases and healed after intensive wound care and oral antibiotics. Adjacent joint function restriction were observed in 6 cases at last follow-up. Induced membrane technique is a simple and reliable technique for the treatment of infectious bone defect. The technique is not limited to the size of the bone defect and the effectiveness is satisfactory.

Ender nailing versus external fixation in the stabilization of type III open tibial shaft fractures.

Management of severe open tibial shaft fractures presents a difficult challenge to the orthopaedic surgeon. They are frequently associated with loss of limb, infection and high levels of morbidity. All the authors considered, now, that there are five keys to successful treatment: antibiotic therapy, radical debridement and pulsed lavage irrigation, stabilization of fracture with minimal further devascularization, early soft tissue coverage and early bone-grafting. It rests, also, a number of controversies in the management of open tibial fractures, not least of which is the method of fracture stabilization: the choice between intramedullary nailing and external skeletal fixation, the use of reamed or unreamed nails. Fifty-seven patients with 62 open fractures of the tibial shaft type IIIA, B and C (Gustilo) were treated between 1.01.1994 and 31.12.1998 in the Department of Orthopaedic Surgery of the Emergency Hospital, Iasi, Romania. There were 29 cases type IIIA fractures, 26 cases type IIIB and 7 cases type IIIC (Mess score showed the viability of the limb). Our patients were 36 males and 21 females; their mean age was 36 years (range 17 to 70). Forty-six patients were injured in road traffic accidents and 11 in other traumatic incidents. In 33 cases the skeletal stabilization was achieved by Ender nailing under general or regional anesthesia. In 15 cases we used a bilateral uniplanar external fixator (Burghele) and 14 fractures were stabilized with an Ilizarov external fixator. We note a secondary amputation after the failure of the revascularization of the limb in a type IIIC fracture. All fractures united; the mean time to union was 30.2 weeks--in the external fixation group and 26.4 weeks--in the Ender nailing group. Malunions occurred slightly more frequently in the external fixation group that in the Ender nailing group (15.7% versus 5.8%). We noted--also--more secondary procedures required in the external fixation group. The infection rate was 3 of 33 (9.1%) in the Ender nailing group compared to 4 deep (13.8%) and 8 pin-tract infection (27.6%) in the external fixation group. Our study suggests that Ender nailing has several advantages over external fixation in the management of severe open tibial shafts fractures. Based on these results, over the last years, in our Department we use mainly the Ender nailing technique, as we consider it a better approach for these type of lesions.

Complex Compound Fracture of Tibia Managed with Distraction Osteogenesis.

The treatment of tibia bone loss can be challenging. The surgical options for the treatment of bone loss include bone transport, vascularized fibula graft, and induced membrane. We present a case of complex compound fracture of tibia with bone loss. Interestingly patient sustained this injury in spite of having intramedullary nail in tibia which was inserted to stabilize previous fracture 9 months prior to trauma. The proximal half of the nail was protruding out of the wound at the time of presentation in emergency department. The nail was removed and stabilized with external fixator after wound closure. The bone gap and nonunion at fracture site was managed with Ilizarov fixator. At the end of treatment patient got satisfactory functional outcome. Ilizarov method is a biologic and comprehensive method for management of bone loss, non union and limb length discrepancy.
