Published: September 2017

Category: Ankle, Ankle Arthritis, Arthroscopy Introduction/Purpose: The role of ankle arthroscopy in managing the consequences of ankle fractures is yet to be fully estab- lished. This study aims to assess this procedure in terms of the accuracy of preoperative diagnosis, re-operation rate and patient- reported outcomes. Methods: We compared two homogeneous groups of 16 patients (32 in total, average age 40.6 years) operated for a fracture of the distal tibia and/or fibula treated with ORIF. For all fractures the AO classification was used. The baseline was 6 months after surgery. Inclusion criteria were: patients aged between 19 and 50 a pre-trauma Tegner score >3, FAOS score <75 at the baseline, R.O.M. <20° vs contralateral; we included patients with well-aligned osteosynthesis and with radiographic union. Patients with open fractures, with osteochondral lesions and with previous were excluded. In the first group we planned an arthroscopy of the ankle from 6 to 12 months after trauma, in the second group, we continued with conservative rehabilitation treatment. All patients were then re-evaluated at 3,6 and 12 months with questionnaires (Tegner activity level, and FAOS). The mean follow-up was 18.2 months. For all data statistical analysis was performed. Results: The results of our case-series showed excellent patient satisfaction (12/14) with a FAOS Score and an improved R.O.M. statistically significant (p <.001) in patients treated with ankle arthroscopy. Eighty percent was able to return to previous activity. The average time until return to sport was 5.3 ± 2.4 months. Seventy percent of the athletes still had occasional pain with sport. Conclusion: The literature on arthroscopic treatment after fracture is still poor but results obtained, even with a limited number of cases, and with a short follow-up, are positive, especially in those patients where the functional demand is highest.

Category: Lesser Toes, Midfoot/Forefoot, Sports Introduction/Purpose: Treatment of fractures to the 5th metatarsal metaphyseal-diaphyseal junction, known as Jones’ fractures, can present challenges in the elite athlete significantly prolonging return to play. Non-operative treatments in elite athletes result in a high incidence of nonunion and secondary fracture. Primary screw fixation remains the standard of care for athletes. However, delayed union and nonunion are still very common despite surgical fixation due to the fracture occurring in a watershed area with decreased healing potential. Bone marrow aspirate concentrate (BMAC) is an autologous source of hematopoeitic and mesenchymal stem cells that has been used in the treatment of poor healing fractures. We hypothesize that open reduction internal fixation (ORIF) augmented with BMAC will improve patient-reported outcome measures following Jones’ fractures in athletes. Methods: This study was a retrospective review of elite athletes that underwent intramedullary screw fixation augmented with BMAC for Jones’ fractures at an academic medical institution. All patients were assessed preoperatively and postoperatively to determine their pain outcomes based on their visual analog score (VAS). Student’s t test was used in statistical comparison of the preoperative and postoperative outcome scores. P < 0.05 was considered significant. Results: A total of 16 elite athletes were treated with ORIF with BMAC for a Jones fracture with a mean age of 22.2 years (range 19–26). There were 9 males and 7 females included in the study. Type of athlete ranged across various sport activities, with all patients functioning at a collegiate and/or professional level of elite athletics. The mean visual analog score for pain decreased from 6.2 preoperatively (range 3-8) to 2.75 postoperatively (range 1-6 p = 0.06). All patients have returned to elite competitive sport activity with reports of minimal to no pain. Conclusion: Intramedullary screw fixation of Jones’ fractures with BMAC results in optimal surgical outcomes in the elite athlete. A higher powered and long-term study with validated patient-reported outcomes is needed to confirm our observations.
Treatment of End-Stage Hallux Rigidus and Impact of Arthrodesis versus Arthroplasty on Patient Reported Outcomes
Authors: Chambers Monique , Hogan MaCalus , LaBaze Dukens 
Published: September 2017

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux rigidus is a degenerative disease of the first metatarsophalangeal joint. Severe, end-stage hallux rigidus can become debilitating with surgical intervention becoming necessary once conservative measures and shoe modifications have failed. Joint salvage procedures include metatarsal phalangeal (MTP) arthrodesis and MTP arthroplasty. The purpose of this study was to assess for differences in patient reported outcomes in two cohorts who underwent fusion or joint reconstruction. Methods: This study was a retrospective review of prospectively collected data of 385 patients from an academic medical institution. Patients who underwent surgical intervention from July 2015 to November 2016 were identified based on CPT codes for MTP arthrodesis (28750) and arthroplasty (28293). We extracted outcome scores including SF12-M, SF12-P, FAAM, and VAS scores. Exclusion criteria included poly-trauma, revision procedures, and lack of pre and post-operative outcome scores. Mann- Whitney t-test was performed using GraphPad Prism version 7.0b for Mac to compare procedure groups, with significance define by a p-value of 0.05. Results: A total of eighteen patients met the inclusion criteria, with 6 who underwent arthroplasty and 12 arthrodesis. The average age was 63.7 amongst the cohort, with a total of 16 female and 2 males. Patients who underwent arthrodesis had better outcomes across all parameters. When comparing preoperative and postoperative scores, arthrodesis patients showed greater improvement of SF12-M (arthrodesis 9 vs arthroplasty -2, p=0.05), and SF12-P (9 vs -16, respectively p=0.05) scores. Arthroplasty patients were more likely to have a decrease in their SF-12 scores. VAS scores and FAAM scores showed no statistical difference between the two cohorts. Postoperative VAS scores were worse in 33% of arthroplasty patients despite surgical intervention, compared to 10% of arthrodesis patients. Conclusion: Our results suggests that both procedures provide a statistically significant difference in pain with several patients having a Global Rate of Change that is “very much better”. However, fusion of the metatarsophalangeal joint results in improved pain and functional outcomes for patients with severe hallux rigidus. These findings are consistent with current reports in the literature, which are mostly case series reports. Larger studies are needed to provide appropriate power and better support the findings of this study.

Published: September 2017

Category: Ankle, Hindfoot, Imaging- Ultrasound Introduction/Purpose: Tendinopathy of the foot and ankle is common and can progress to become incapacitating. The most frequently affected tendons in the foot and ankle are the posterior tibial, peroneal, and Achilles. Studies have found a lifetime incidence of 5.9% in sedentary people and as high as 52% in athletes for Achilles tendinopathy. Previous studies demonstrated that ultrasound (US) of the soft tissues of the foot and ankle is a highly effective tool that can evaluate nearly every anatomical structure. Its lack of ionizing radiation, low cost, and painless nature make it a viable tool for foot and ankle evaluation. We sought to utilize US to determine normal values for the Achilles, peroneal, and posterior tibial tendons in patients presenting to the foot and ankle clinic. Methods: Patients were evaluated prospectively via a standardized US examination protocol from 2015-2016. Subjects who agreed to participate received a bilateral lower extremity ultrasound performed by a musculoskeletal ultrasonographer of the posterior tibial, peroneus longus, peroneus brevis, and Achilles tendons. Images were obtained in both the transverse and longitudinal axes above and below the malleoli and saved for analysis and measurement calculations. When indicated, color flow Doppler was utilized to assess for hyperemia and recorded. The imaging for each tendon was acquired with the patients in standardized positions on the examining table. Results: A total of 200 patients with 400 extremities were identified, consented, and participated in the study. Measurements for each patient were recorded above and below the malleoli for each tendon. Most tendons demonstrated a normal distribution as illustrated in the representative Figure 1 of the peroneus brevis above the lateral malleolus. Values and distributions curves were similarly calculated for each tendon at each point of measurement. Patients with suspected tendinopathy frequently had an increase of two standard deviations above the mean. Conclusion: This is the largest studies to characterize the measurements of the posterior tibial tendon, Achilles, and peroneal tendons in patients that present to a foot and ankle clinic. This baseline data can assist clinicians in their diagnostic ability with US. Given its low cost, lack of ionizing radiation and dynamic ability along with an improved understanding of normative data it will likely become an increasingly utilized diagnostic modality.
Akin osteotomy as an adjunct to hallux MTPJ fusion
Authors: Damany Devendra , Dalwai Ramesh 
Published: September 2017

Category: Midfoot/Forefoot, Hallux MTP fusion Introduction/Purpose: It is not uncommon to note residual valgus at the hallux interphalangeal joint when performing a hallux MTPJ fusion. On occasion, despite optimum positioning of hallux MTPJ for fusion, we found that in some cases the hallux was still abutting the second toe. We noted that these cases had either a high hallux interphalangeus valgus angle or the proximal phalanx had a shorter, concave lateral border due to eccentric wear. These two variables were difficult to correct despite optimum positioning of the hallux MTPJ. Consequently the hallux abuts the second toe causing irritation. We have used Akin osteotomy as an adjunct to hallux MTPJ fusion to address this intraoperative problem Methods: Between 2013 to 2016 this technique was utilised in 16 patients in whom residual hallux valgus interphalangeus was noted once the hallux MTPJ was stabilised in the appropriate position. We used two 4.0 mm AO cannulated partially threaded screws inserted in a crossed configuration for MTPJ fusion and a 8 mm x 90 degree varisation staple for the Akin osteotomy. The Akin osteotomy was performed in the mid to distal diaphyseal region of the proximal phalanx to avoid the screw position. Postoperatively, patients were given a toe spica plaster cast and were advised to walk in a heel weight bearing wedge shoe for six weeks. Results: Despite the osteotomy not being in the metaphyseal region, we have not encountered any immediate post-operative complications. We accept that this technique may not be suitable when using plates and screws for fusion but would be suitable for use with screws or staples. We have not encountered any postoperative complications. All hallux MTPJ joints have fused and Akin osteotomies have healed uneventfully Conclusion: This technique has not been reported before. Akin osteotomy is commonly used as an adjunct to corrective hallux valgus surgery. It is a relatively quick and reproducible technique with minimal incidence of complications. We suggest that this technique be considered when carrying out a hallux MTPJ fusion, although may not be required in all cases.

Published: September 2017

Category: Ankle Introduction/Purpose: The aim of the study was to assess the relationship between symptomatic osteochondral lesions of the talus (OLTs) and age, Body Mass Index (BMI), quality of life (QOL), size and anatomic location. Methods: Fifty-two patients with chronic OLTs were analyzed including BMI, Visual Analgoue Scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS), Short-Form Healt Survey (SF-12 divided into Mental (MCS) and Physical (PCS) score) and the 12-Item General Health Questionnaire (GHQ-12). Every patient underwent magnetic resonance imaging (MRI) and computed tomography (CT) examinations. We carried out a sub-analysis by dividing the talus into 6 areas, 3 vertical (medial, central and lateral group) and 3 horizontal (anterior, middle and posterior group). Results: There were 31 (60%) male and 21 (40%) female patients. Mean MCS and PCS resulted respectively 43.9 and 35.2. OLTs were located as follows: medial 20 (38.50%); central 13 (24.0%); and lateral 19 (36.50%); anterior 24 (46.15%); middle 16 (30.77%); and posterior 12 (23.08%). No significant differences were found among different groups with the exception of the anterior and posterior group for MCS (p=0.021). In central group we identified a negative correlation (R=-0.672) between aging and AOFAS and a positive correlation between BMI and lesion size. We found a positive correlation between CT and MRI in each group. Conclusion: OLTs impact patients quality of life particularly in the physical component. Additionally, in patients with central lesions we found a positive linear correlation between lesion size and BMI and a worsening of the ankle with increasing age.

Published: September 2017

Category: Ankle, Arthroscopy, Trauma Introduction/Purpose: High fibula fractures, including Maisonneuve and Weber type C fractures are commonly associated with syndesmotic injuries resulting in subluxation and dislocation of the ankle. These injuries to the joint are rarely evaluated or addressed during operative fixation, which generally consists of open reduction internal fixation of the fibula with or without fixation of the syndesmosis. Chondral lesions and loose bodies in ankle fractures may predict a poor result and can be addressed using arthroscopy to avoid exacerbating articular damage. The purpose of this study is to identify the frequency and severity of articular pathology in Weber C and Maisonneuve fibula fractures. Methods: A single surgeon case series of operatively managed ankle fractures with arthroscopic assessment from 2011-2015 was retrospectively reviewed. Inclusion criteria were patients with AO 44-C ankle fractures who were aged >17 and underwent arthroscopic assessment of the ankle joint prior to open reduction and internal fixation. Patients were excluded from the series if they presented <2 weeks from the time of injury, had a pilon variant, or had incomplete medical records available. Demographic information on the patients including age, sex, and BMI were collected. Information on mechanism of injury was recorded. Operative reports were reviewed and the presence of chondral injury and loose bodies was recorded. Descriptive statistics were performed on the collected data. Results: 18 patients (12 male, 6 female) with a mean age of 38.3 years (range 17-61; SD 13.9) were included in the case series. The average BMI 29.6 (SD 6.92). Five of the included fractures were Maisonneuve fractures while the remaining 13 were Weber C ankle fractures. The mechanism of injury of the fracture was low energy in 12, high energy in 1, and unknown in 5. On arthroscopic examination, 12 (66.7%) of the fractures were associated with full thickness articular cartilage injury requiring formal chondroplasty, 16 (88.9%) were associated with a minimum of partial articular damage, and only 2 (11.1%) had no articular damage identified on arthroscopy. Additionally, 12 (66.7%) had loose bodies that were removed during ankle arthroscopy. Conclusion: This study adds to a growing collection of literature concerning chondral injuries during ankle fractures. The data from this study suggest that AO 44-C fibular fractures are associated with a high rate of intraarticular pathology that can be effectively identified and managed during arthroscopy. Prospective studies are required to determine if there are therapeutic benefits to routine ankle arthroscopy in AO 44-C ankle fractures.

Category: Hindfoot Introduction/Purpose: Reconstruction of a symptomatic adult flatfoot is an involved operation with a long recovery period. No previous studies have looked at the occupational or functional results of athletically active patients who have undergone this surgery. In the United States military, the rates of return to unrestricted active duty are unknown. Methods: A retrospective review of all active duty military patients who underwent a reconstructive surgery for adult acquired flatfoot surgery at a single institution from January 2001-2015 was performed. Surgical, inpatient, and outpatient databases were searched via CPT and ICD9 codes. Approximately 1300 cases with potential flatfoot reconstructive surgery were identified. Only those patients with the diagnosis of flatfoot treated with both a boney procedure and a soft tissue procedure were included. Patients had to have at least one year follow-up or follow-up to the point of maximum medical benefit as defined by the operative provider. Final disposition of the patients had to have been recorded in the medical record. Three possible outcomes were utilized in the review of this cohort: patient returned to duty without restrictions, patient returned to active duty with restrictions, or patient separated from active duty due all or in part to this medical condition. Results: Fifty patients met inclusion criteria. 30/50 patients (60%) remained on active duty with permanent duty restrictions, and only two of 50 patients (4%) returned to full duty without restrictions. 20/50 (40%) underwent a Medical Evaluation Board (MEB) to separate from the military. A difference was noted in terms of the hindfoot realignment procedure performed: the probability of an MEB is higher for those patients who had a lateral column lengthening procedure than those who were treated with a medializing calcaneal osteotomy. Conclusion: The sample size is the largest study to date of patients with surgical correction for symptomatic pes planus. The results demonstrate that a service member with symptomatic pes planus requiring surgery faces a 96% chance of failure to return to pre-injury level of function. While some (60%) were able to remain on active duty with restrictions, there is a 40% chance that service members will face separation from the military due to their foot pain. Furthermore, patients treated with a lateral column lengthening had a higher probability of being medically discharged than those who had a medializing calcaneal osteotomy.

Published: September 2017

Category: Basic Sciences/Biologics, Lesser Toes, Midfoot/Forefoot Introduction/Purpose: Hammertoes, crossover toes, and claw toes are common deformities and can be a major source of pain and dysfunction. These deformities result from instability of the metatarsophalangeal (MTP) joint due to incompetence of the plantar plate and/or collateral ligaments. Non-operative management is the first line of treatment. When non-operative treatment is unsuccessful, surgical interventions have been described. Newer surgical techniques focus on performing anatomic repairs of plantar plates. The vasculature of the foot has been well studied, but the vascular supply of the plantar plate has not been described. This study presents a new technique for imaging the microvasculature of the lesser toe plantar plates through micro- computed tomography (micro-CT) in order to better understand tear pathology and the capacity of healing with plantar plate repairs. Methods: The posterior tibial and dorsalis pedis arteries of a fresh frozen human cadaver foot were dissected and cannulated at the ankle for perfusion distally. After administration of an anticoagulant, each artery was perfused with Microfil® Silicone Rubber, a contrast agent. The compound was then allowed to cure, and the foot was fixed in formalin. The foot was sectioned through the metatarsal shafts for imaging, and imaging of the lesser toe MTP joints was performed using a Bruker Skyscan 1176 micro-CT scanner at 18 micron slices. Computerized reconstruction of the images was performed for three dimensional visualization of the vasculature. Results: Post-perfusion imaging of the lesser toe MTP joints using micro-CT allows for visualization of the plantar plate microvasculature. Preliminary imaging suggests that micro-CT is a useful modality for analysis of the blood supply of the plantar plate. Conclusion: Anatomic repair of the plantar plate has become a viable treatment option for MTP joint instability. One important question that remains to be answered is whether plantar plate tears have the capacity to heal. We present a novel technique for imaging of lesser toe plantar plate microvascularity using micro-CT. Preliminary results of post-perfusion imaging of the plantar plate are promising for developing a better understanding of its blood supply. Further definition of the plantar plate vascular supply will help clinicians understand the capacity for healing after repairs and may provide some insight to the biological causes plantar plate tears.
