Introduction/Purpose:

Coalition of the naviculo-medial cuneiform joint (NCJ) is a relatively rare condition among the tarsal bone coalitions. Thus, optimal treatment is still largely unknown. There is a paucity of literature, with few cases documenting arthrodesis of the NCJ in adults with varied outcomes. As the NCJ contributes to the majority of motion along the medial column of the foot, arthrodesis of the joint may cause excessive stress on adjacent joints. Furthermore, the nonunion rate of NCJ is reportedly high, ranging from 3 to 15%. The purpose of this study was to report the outcomes of simple coalition bar excision in patients with NCJ coalition. Additionally, we investigated preoperative abnormal conditions around the NCJ using weight bearing computed tomography (WBCT).

Methods:

We retrospectively identified 21 feet in 18 prospectively followed patients from 2010 to 2018 who underwent simple coalition bar excision of NCJ in our institution. Chart review was performed to retrieve demographic data of the patients, clinical presentation findings, and concomitant procedures with coalition bar excision. Radiographically, the location and morphological pattern of the coalition were analyzed. Several angular parameters including medial arch sag angle (MASA) were measured on weightbearing x-rays to see if there are any angular collapse at NCJ after coalition bar excision (Figure 1). The existence of abnormal conditions adjacent to the NCJ such as arthritis of the first and second tarsometatarsal joint (TMTJ) and talonavicular joint (TNJ) were assessed using WBCT (n=17). Clinically, pre- and postoperative visual analogue scale (VAS) and foot function index (FFI) were compared to assess for improvement in patient-reported outcomes.

Results:

The mean age of the patients was 30.9 years (range, 16-62) and the follow-up was 15.9 months (range, 12-24). Majority of the patient had fibrous coalition at the plantar-medial aspect and only one patient had bony coalition. The morphology of fibrous coalition was classified as irregular (n=8), cystic (n=1), and combined (n=11) based on CT findings. Intraoperatively, the motion of the NCJ was identified in every patient after coalition bar excision. WBCT revealed 15 feet (71.4%) having at least one abnormal finding around the NCJ (First TMTJ plantar gap; n=10, second TMTJ narrowing; n=9, first TMTJ spur & irregularity; n=2, TNJ spur; n=1). Pre- and postoperative MASA did not change significantly (p=0.932). There was significant improvement in VAS and FFI at final follow-up (p<0.001)

Conclusion:

A considerable proportion of patients with NCJ coalition had at least one radiographically arthritic feature at adjacent joints preoperatively, which may be caused by the restriction in motion associated with NJC coalition. Simple coalition bar excision in adults resulted in satisfactory outcomes without NC joint angular deterioration, while restoring motion at the joint.

Introduction/Purpose:

The aim of this study was to describe and evaluate the morphologic characteristics of the medial malleolar fragment in ankle fractures and suggest the guideline for proper fixation of the fragment

Methods:

From August 2011 to June 2018, 172 cases were enrolled. There were performed the operation in ankle fractures with a medial malleolar fragment. All cases were divided into three types, based on the transverse fracture line of the medial malleolar by the CT (computed tomography) scan; type 1 was involved in the anterior colliculus, type 2 was the intercollicular groove and type 3 was the posterior colliculus. All cases were classified by Lauge-Hansen classification and compared with the groups statistically. The fixation methods by the groups were reviewed and compared. All cases were analyzed by SPSS 19.0, the p-value was less than 0.05.

Results:

According to the CT scan, type 1 was 14 cases (8.1%), type 2 was 48 cases (27.9%) and type 3 was 110 cases (63.9%). Based on the Lauge-Hansen classification, SER (supination-external rotation) type was 136 cases(76.4%), PER (pronation-external rotation) was 30 cases(17.4%) and PA(pronation abduction) was 8 cases(4.7%).In SER type, type 1 was 6 cases(4.4%), 2 was 42 cases(30.9%) and 3 was 86 cases(63.2%). In PER type, 1 was 6 cases (20%), 2 was 4 cases (13.3%) and 3 was 20 cases (18.9%). In PA type, 1 was 2 cases (25%), 2 was2 cases (25%) and 3 was 4 cases (50%). The fixation methods were various, such as a tension band wiring, 4.0 cannulated screw, hook plate.

Conclusion:

The morphology of a medial malleolar fragment based on CT scan in ankle fractures were 3 types. There was common a morphology involved the posterior colliculus, Type 3. We suggest that the operators should choose the proper fixation method by the morphology of the fragment and should be careful to avoid the injury of the posterior tibialis tendon.

Introduction/Purpose:

This study aimed to compare the clinical results between osteochondral autologous transplantation (OAT) and dorsiflexion closing wedge metatarsal osteotomy (DCWMO) in symptomatic adult patients with late-stage Freiberg disease.

Methods:

Between 2012 and 2017, patients with late-stage Freiberg disease surgically treated with OAT (12 patients) or DCWMO (15 patients) were retrospectively identified. The American Orthopaedic Foot & Ankle Society-lesser MTP- interphalangeal (AOFAS-LMI) score, visual analog scale score for subjective pain, and range of motion (ROM) were determined preoperatively and at final follow-up. Postoperative complications were also recorded.

Results:

The AOFAS-LMI score at final follow-up was significantly greater in the OAT group than in the DCWMO group (95.7 vs. 87.9, p<0.001), whereas plantarflexion at final follow-up was significantly lower in the DCWMO group than in the OAT group (30.0 degrees vs. 24.0 degrees, p=0.037). The DCWMO group reported more postoperative complications including postoperative joint stiffness, deformity, and pain recurrence. In the OAT group, one patient complained of mild knee pain.

Conclusion:

OAT seemed a better procedure for late-stage Freiberg disease compared with DCWMO in adult patients in terms of postoperative functional score and ROM, with lesser complication rates.

Ankle; Ankle Arthritis

Introduction/Purpose:

The aim of current study is to perform long-term survival analysis for TAA of 5619 cases, and identify patient risk for failure of TAA.

Methods:

Total of 7516 cases of TAA were identified from national insurance claim data of South Korea during 2007 to 2018. After exclusion of bilateral cases and cases performed on 2018, total 5619 cases of primary TAA cases were included. TAA failure was defined as case with revision arthroplasty or case with TAA implant removal and arthrodesis after primary TAA. Patient age, hospital size, comorbidities were included for survival analysis. Kaplan-Meier survival analysis was performed during study period, and Multivariable Cox regression analysis were performed.

Results:

During study period, five-year survival rate was 95.4%, and 10-year survival rate was 91.1%, and mean survival duration was 9.6 years. Regression analysis revealed that younger age (< 65, adjusted hazard ration (AHR), 1.812; p< 0.001), chronic pulmonary disease (AHR, 1.476; p= 0.013), diabetes (AHR, 1.443; p= 0.014), alcohol consumption (AHR, 1.524; p= 0.032) showed significant high odds ratio for TAA failure.

Conclusion:

Current study was performed with largest cohort with TAA procedures in literature. 10-year survival rate was 91.4%, young age and some comorbidities revealed as significant predictor for TAA failure.

Ankle; Arthroscopy

Introduction/Purpose:

The current scientific evidence for the clinical and sports-related outcomes of the surgical treatment of osteochondral lesions of the talus (OLTs) with arthroscopic microfracture (MF) in elite athletes is scarce. The purpose of curretn study is to evaluate the clinical outcomes and return to sports activity after arthroscopic MF for OLTs in elite athletes.

Methods:

The files of 41 elite athletes (mean age 19.34 +- 3.76 years) who had undergone arthroscopic MF for OLTs at our institution between January 2011 and September 2015 were retrospectively reviewed. The Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot and visual analog pain (VAS) score, time and rate of ‘return-to-competition’ (RTC, defined as return to an official match for at least one minute after treatment), and rate of ‘return- to-play’ (RTP, defined as participation in at least two entire seasons after treatment) were used to evaluate the outcomes. We compared athletes who were able to RTP (RTP-group) with those who were not (No-RTP group).

Results:

The mean follow-up was 54.9 +- 13.72 months. All five subscales of preoperative FAOS were significantly improved at the final follow-up. The mean preoperative AOFAS hindfoot score of 74.46 +- 8.10 improved to 91.62 +- 2.99 (P < 0.001) at the final follow-up. The mean preoperative VAS score of 5.44 +- 1.57 improved to 2.66 +- 1.04 (P < 0.001). All patients achieved RTC (100%) at mean time of 5.45 +- 3.18 months, and 74.4% of patients were able to RTP. The RTP-group showed significantly smaller lesions compared to the No-RTP group (71.52 +- 43.29 vs. 107.00 +- 45.28 mm2, P = 0.009). The cut-off OLT size for predicting RTP was 84.0 mm2, with a sensitivity of 90.0% and specificity of 75.9%.

Conclusion:

All athletes were able to RTC at average of 5.45 months after MF for OLTs, and 74.4% were able to RTP. The only prognostic variable for RTP was lesion size, and its predictive cut-off was 84 mm2.
Hypoalbuminemia is an Independent Predictor of 30-Day Postoperative Complications Following Surgical Fixation of Ankle Fractures

Introduction/Purpose:

Malnutrition is known to be negatively associated with outcomes after multiple orthopedic procedures. We hypothesized that admission albumin levels, as a maker for malnutrition, would correlate with postoperative outcomes. The purpose of this study is to investigate this relationship following surgery for ankle fracture.

Methods:

This is a retrospective cohort study of the ACS-NSQIP database. Patients undergoing operative fixation of an ankle fracture were identified. 6,138 patients with albumin available for analysis were identified. Baseline patient information, preoperative serum albumin levels, 30-day postoperative complications, readmission, reoperation, and length of stay data were then collected. Poisson regression with robust error variance was performed to assess the effect of preoperative serum albumin level on postoperative outcomes.

Results:

6,138 patients with albumin available for analysis were identified in the database. The mean albumin level was 3.86 g/dl and 20.3% of patients with available albumin levels were hypoalbuminemic. Multivariate analysis revealed that albumin level <3.5 g/dl is an independent risk factor for complication (RR 1.42, 95% CI 1.13-1.78, p=0.002) and readmission (RR 1.54, 95% CI 1.13- 2.08, p =0.006). Additionally, when analyzed as a continuous variable, albumin level was negatively correlated with risk of mortality (RR 0.37, 95% CI 0.19-0.72, p=0.003). Patients with hypoalbuminemia also had significantly longer length of stays (4.5 v. 2.1 days, p<0.001).

Conclusion:

While complication rates after fixation of ankle fractures remain low, hypoalbuminemia is a predictor of postoperative course. Malnutrition, therefore, may help inform the decision between surgical and conservative management of patients with ankle fractures potentially amenable to non-operative management. Additionally, hypoalbuminemia should trigger heightened awareness and prophylactic therapy where appropriate.
Novel Measurement Technique for Talar Height Assessment in Total Ankle Arthroplasty
Authors: Kulwin Robert , Haddad Steven L.
Published: November 2020

Category:

Ankle Arthritis; Other

Introduction/Purpose:

Talar and calcaneal height have been identified as important not only to the biomechanics of ankle joint function but of the adjacent joints of the hindfoot as well. Many proposed measurement systems have been introduced to the literature to assess talar height in ankle arthroplasty, but have significant shortcomings. The malleoli frequently develop osteophytes after total ankle arthroplasty. If the subtalar joint is fused or arthritic, methods relying on landmarks such as the angle of Gissane are similarly unreliable. Lastly, subsidence is often asymmetrical. Measuring from the highest point of the talar component may not be reflective of functional talar height. We propose using adjusted talocalcaneal height to assess the functional restoration of talar height.

Methods:

Pre and post-operative radiographs and weight bearing computed tomography (WBCT) were reviewed for 40 cases of failed total ankle arthroplasty undergoing revision. Bony landmarks were assessed for consistency over a time course of two to four years post operatively. Talocalcaneal height was measured along from the center of the tibial component of ankle arthroplasty on weight bearing lateral radiographs and on sagittal and coronal reconstructions on WBCT (fig 1). Measurements on radiographs and WBCT were compared for agreement. For implants where lateral radiographs could not be used (AgilityTM, Depuy), sagittal and coronal WBCT was used.

Results:

Average adjusted talocalcaneal height as measured on lateral radiographs, sagittal WBCT, coronal WBCT, and averaged values from sagittal and coronal WBCT was 68mm, 67.4mm, 68.5mm, and 68mm respectively. There was not a significant difference between the lateral radiographs and WBCT measurement methods (p= 0.30, 0.37, 0.46), and correlation was 0.99 for all methods. Measurements did not vary in cases of angular subsidence or subtalar fusion.

Conclusion:

Adjusted talocalcaneal height is a reproducible and reliable measurement to assess talar height. It accommodates procedures frequently performed in tandem with total ankle arthroplasty such as calcaneal osteotomy and subtalar fusion. It relies on a single, static bony landmark, and remains valid in cases of asymmetric subsidence. Lastly, it incorporates calcaneal height, which affects not only ankle joint mechanics but adjacent joint mechanics as well.
A Comparison of Arch Index, Foot Posture Index and Surgeon Observation for Foot Type Classification

Basic Sciences/Biologics

Introduction/Purpose:

Foot morphology is a key aspect of patient evaluation. Individuals with Pes planus usually have medial foot pain; those with Pes Cavus commonly have pain over lateral foot. Foot Posture Index (FPI) is a qualitative measure that uses six specific physical exam parameters. Arch index (AI) is a quantitative measure in which the footprint is photographed and measured. Radiographs allow for visualization of the bone and used to directly measure parameters of foot morphology such as calcaneal pitch (CP). The purpose of this study was to determine the sensitivity and specificity of surgeon observation, FPI, and AI in determining foot type, with CP serving as the reference standard. Our hypothesis is that surgeon observation will be more sensitive and specific than FPI and AI for identifying foot type.

Methods:

Following institutional review board approval and informed consent, we examined 41 adults (82 Feet) (average age 37.8+-17.6 yrs.; range: 20 to 68 years old; 20F/21M) without history of prior foot or ankle injury. Subject evaluation included bilateral FPI exam, lateral and hindfoot standing radiographs, pedographs, and weightbearing photographs. Three authors were trained to perform standardized FPI assessments. The radiographs and photographs were presented in a randomized order to a board-certified foot and ankle orthopaedic surgeon to classify a foot as either planus, cavus or normal (Figure 1). Calcaneal pitch was measured for each foot by finding the angle between the inferior surface of the calcaneus and the supporting surface, with normal classified as 18°-32°, planus <18° and, and cavus>32°[2,3]. Arch index was calculated for each foot from pedograph, with normal classified as 0.21 to 0.28, planus < 0.21 and cavus >0.28.

Results:

The gold standard calcaneal pitch measurements identified 12 planus, 57 normal, and 13 cavus feet. Surgeon observation was the most sensitive for identifying planus feet and most specific for identifying cavus feet (Table 1). Arch index was the most sensitive for identifying cavus feet and most specific for identifying both planus and normal feet. FPI was most sensitive for identifying normal feet. The correlation between raw scores on the FPI and AI to CP were weak to moderate, -0.387 and -0.526, respectively (p<0.01).

Conclusion:

Surgeon observation is the only method that had a sensitivity over 0.50 for two different foot morphologies. FPI does not have the highest specificity for any particular foot type; however, a specificity of 0.844 and 0.971 for planus and cavus feet demonstrates that FPI is a suitable modality for evaluating pathologic morphology. Our specificity is close to a prior reported 0.932. These similarities in statistics reassure us that our methods are consistent with prior studies. Limitations of the study include small sample size and a single surgeon reviewing imaging. [Table: see text]

Introduction/Purpose:

Restoration of normal anatomic alignment is most important aspect of the minimally invasive plate osteosynthesis (MIPO) for tibia fracture. The purpose of this study was to verify the usefulness of ultrasonography of MIPO in tibia fractures.

Methods:

Of the tibia fracture patients were admitted to the emergency department patients who plan to MIPO surgery were enrolled. We measured maximum angular formation in posteromedial and anterior edge of tibia using ultrasonography (US). And then, we measured maximum angular formation using mobile C-arm images after closed reduction in operating room. The accuracy was measured and compared using 3-dimensional computed tomography (3D-CT).

Results:

There was no significant difference in accuracy between C-arm and US. However, the use of C-arm during surgery was reduced by using US. By using US, we could determine that the reduction is adequate without the lateral and oblique C-arm images.

Conclusion:

The use of US is useful in reduction for tibia fracture. It seems that US is effective for confirmation of reduction state and considered safe and non-invasive because it can reduce the radiation exposure by using C-arm.
Comparison of Clinical Outcomes after Arthroscopic Anterior Talofibular Ligament Repair with or without Inferior Extensor Retinaculum Augmentation

Introduction/Purpose:

Though several arthroscopic surgical techniques for the treatment of lateral instability of the ankle have been introduced recently; the effect for the inferior extensor retinaculum augmentation is remained unclear. The purpose of this study was to compare the clinical outcomes after arthroscopic anterior talofibular ligament (ATFL) repair with or without additional retinaculum augmentation.

Methods:

We performed a retrospective review between 2017 and 2018 of 61 consecutive patients who underwent arthroscopic ATFL repair surgery for chronic ankle lateral instability. The exclusion criteria were previous surgery on affected ankle and combined medial ligament instability. Demographic data were evaluated including age, gender, smoking, Body mass index, generalized hyperlaxity and concomitant lesions. Patients were divided into two groups according to whether retinaculum repair or not. Clinical results were analysed to compare groups A and R preoperatively and at minimum follow-up of 1 years by using the Visual Analogue Scale, American Orthopaedic Foot & Ankle Society (AOFAS) score, Foot and Ankle Outcome score (FAOS), and Karlsson Ankle Functional Score. Radiologic outcome evaluations were performed preoperatively and at 2 year postoperatively at final follow-up using anterior talar translation, and talar tilt angle.

Results:

A total of 62 patients were included in this study. Patients were divided into two groups: group A consisted of 29 patients who underwent only arthroscopic ATFL repair and group R consisted of 32 patients who underwent arthroscopic ATFL repair and additional retinaculum augmentation. There was no difference statistically between two group in demographics (Table 1). All clinical scores were improved after surgery in both groups. (P<0.001) There were no differences were found in VAS, AOFAS score, total FAOS and Karlsson score between two groups. However, sports activity unit in FAOS, there were significant differences between group A (71.4 +- 8.1) and group R (83.4 +- 8.6) (Table 2). (p=0.032) Radiographic data also showed no differences (Table 3).

Conclusion:

Arthroscopic ATFL repair achieved improved outcomes postoperatively with or without retinaculum augmentation. However, among physically active patients with chronic ankle lateral instability, arthroscopic ATFL repair with retinaculum augmentation results in better sports activity unit in FAOS as compare with arthroscopic ATFL repair alone.

Introduction/Purpose:

There is no standard guideline for prescription opioids for postoperative pain management following outpatient foot and ankle surgery. Multiple previous studies demonstrated that opioids were overprescribed. The purpose of this study was to prospectively investigate opioid consumption using multimodal analgesia regimen after two of the most common forefoot surgeries: isolated hallux valgus correction or 1st metatarsophalangeal (MTP) joint arthrodesis.

Methods:

We prospectively investigated opioid prescription and consumption of total 21 patients who underwent isolated hallux valgus correction with distal soft tissue procedure and proximal first metatarsal crescentic osteotomy or 1st MTP joint arthrodesis. Postoperative pain was managed using multimodal analgesia including oxycodone, ibuprofen, acetaminophen, and regional ankle block. Patients were instructed to take 5mg of oxycodone every 4 hours as needed, and 600 mg of ibuprofen as well as 1,000 mg of acetaminophen every 8 hours regularly. The number of pills patients consumed for oxycodone was recorded at postoperative follow-up at 1-week, 2-week, 4-week, 8-week, and 12-week. Subgroup analysis was performed to evaluate opioid consumption according to the prescription type: Only oxycodone was prescribed in group A while oxycodone as well as prescription strength ibuprofen and acetaminophen were prescribed in group B. Another subgroup analysis in opioid consumption was performed based on the quantity of opioid prescription and procedure type.

Results:

The overall mean opioid consumption in 12 weeks of the postoperative period was 16.2 pills per patient with an average of 37.3 pills prescribed. Lower opioid consumption was noted in group B when prescription ibuprofen and acetaminophen were prescribed compared to group A when patients took over-the-counter (OTC) ibuprofen and acetaminophen: 9.0 pills vs 24.1 pills, respectively (P = 0.036). There was a trend showing higher opioid consumption in patients prescribed greater than 30 pills of oxycodone compared to less than or equal to 30 pills: 22.0 pills vs 9.8 pills, respectively (P = 0.099). No significant difference was found in opioid consumption according to the procedure type: 15.8 pills in hallux valgus correction vs 16.5 pills in 1st MTP joint arthrodesis (P = 0.750).

Conclusion:

This study showed that on the average, patients took 16.2 pills out of 37.3 pills of the prescribed oxycodone after isolated hallux valgus correction or 1st MTP joint arthrodesis using our multimodal analgesia regimen. Patients who were prescribed prescription strength ibuprofen and acetaminophen consumed opioid significantly less than those who took the OTC strength. No significant difference was noted in opioid consumption between isolated hallux valgus correction and 1st MTP joint arthrodesis.

Trauma; Ankle

Introduction/Purpose:

The BOAST (British Orthopaedic Association Standards for Trauma) guidelines do advise that open pilon fractures amongst other open lower limb fractures need to be treated at a specialist centre with Orthoplastic care. The purpose of this study was to determine clinical outcomes in patients with open pilon fractures treated as per BOAST guidelines including relatively aggressive bone debridement.

Methods:

A retrospective analysis of open pilon fractures treated between 2014 and 2019 was conducted. Injuries were graded according to the Gustillo-Anderson classification and all patients were included for the assessment of the rate of infection and fracture healing. Functional outcome assessment was performed in all patients according to the American Orthopaedic Foot & Ankle Score (AOFAS) at 6 months after definitive surgery. Initial wound with bone debridement and application of a spanning external fixator was performed within an average of 13.5 (Range: 3-24) hours. Definitive fixation was performed when the wound was healed, with the mean time from primary surgery to definitive surgery being 24.5 (Range: 7-60) days.

Results:

There was a total of 20 patients. The mean age was 50.5 (Range: 16-88) years. Follow-up was for an average of 25.1 (Range: 9-36) months. There were 3 patients with Gustilo Type I injuries, 6 with Type II, 4 Type with type IIIa and 7 with Type IIIb injuries. Average time to bone union was 9.3 (Range: 4-18) months. The mean AOFAS score was 64.4 (Range: 15-90). Definitive treatment via Taylor Spatial Frame was performed on 18 patients, while 2 patients had an Ilizarov frame. A corticotomy was performed on 4 patients with critical bone defect post debridement, while 3 patients had Stimulan beads with antibiotics. There were no cases of deep infection, however a superficial wound infection was found in 9 patients (45%).

Conclusion:

Results of our study suggests that the use of staged wound debridement including relatively aggressive bone debridement in conjunction with antibiotics, external fixators and patient tailored timing of definitive surgery achieves low rates of wound infection and complications for patients with open pilon fractures. We suggest treating these fractures with the availability of Orthoplastic care and with an MDT approach.

Introduction/Purpose:

Tibiocalcaneal (TC) arthrodesis is commonly performed in patients with severe hindfoot disease. These include severe Charcot deformities, ankle malformations, chronic osteomyelitis (COM), and avascular necrosis (AVN). The talar vasculature becomes disrupted to the point that the bone can no longer be salvaged. The procedure involves performing a talectomy and fusing the tibia to the calcaneus. This helps in preserving the remaining hindfoot anatomy while allowing the patient to regain function and mobility. Our study highlights certain risk factors that influence the rate of postoperative complication after tibiocalcaneal surgery.

Methods:

We retrospectively reviewed the charts of 18 patients from a single institution who underwent tibiocalcaneal arthrodesis between the years of 2011 and 2019. Preoperative diagnoses, comorbidities, post-operative outcomes were noted among all patients. Then, the rates of non-union, below-knee amputations, revision surgeries, postoperative infections, and hardware failure were recorded. This data was then analyzed to determine which preoperative and perioperative factors affected postoperative outcomes for patients after tibiocalcaneal arthrodesis surgery.

Results:

Nonunion was the most commonly reported complication in this series. Eight of the eighteen patients were documented to have nonunion including three patients with stable pseudarthrosis. Diabetic patients had a slightly higher incidence of nonunion (4 of 7 patients) compared to those without diabetes (4 of 11 patients). Of the 9 patients diagnosed with Charcot arthropathy, 5 had nonunion. Three of five individuals with a BMI ranging from 25-30, and four of six individuals with a BMI of greater than 30 had a nonunion. Infection was a post-operative complication for four of the eighteen patients. Two of the four patients had multiple comorbidities in addition to chronic infections in the joint which were recurrent after surgery.

Conclusion:

In conclusion, TC arthrodesis provides a viable option for high risk patients with complicated ankle pathology who have not had successful outcomes from previous treatment. It is not without complications considering the comorbidities the patients present with before requiring this procedure. Further studies are necessary in order to validate the trends of outcomes and comorbidities of patients with TC arthrodesis. [Table: see text]

Introduction/Purpose:

Hallux rigidus is one of the most common toe pathologies in patients greater than 50 years old. While first metatarsophalangeal (MTP) arthrodesis is utilized to improve pain and function, older patients are often considered to be higher risk surgical candidates. There are minimal data on outcomes of MTP arthrodesis and no studies comparing outcomes between geriatric and younger patients.

Methods:

This is a single center, prospective study of all patients who underwent MTP arthrodesis between August 1, 2015 and July 1, 2018. Patient reported-outcomes were assessed utilizing the Short Form Health survey (SF-36), LifeSpace Assessment survey (LSA), and visual analogue scale (VAS) for pain administered preoperatively as well as 6-months and 1-year postoperatively. Baseline characteristics and surgical outcomes were collected from the electronic medical record. All operations were performed by one foot and ankle fellowship-trained orthopedic surgeon. Clinical and patient-reported outcomes were compared between patients <65 years-old and ≥ 65 years-old.

Results:

Of 143 included patients, 79 were placed in the younger (mean of 56.5 years) and 64 were in the older (mean of 72.0 years) cohorts. Compared to the younger cohort, the older was more predominantly female (95.3% older group, 77.2% younger group, p=0.002). More patients in the older cohort had hypertension (73.4% older group, 50.6% younger group, p=0.005) and coronary artery disease (9.4% older group, 0.0% younger group, p= 0.005). Both age groups had similar postoperative outcomes, including antibiotic therapy for superficial infections, surgical incision and drainage, deep vein thrombosis, deformity recurrence, or revision surgery. No differences were detected in SF-36, LSA, and VAS surveys administered at baseline, 6-months postoperative, or 1-year postoperative between younger and older patients.

Conclusion:

Despite more comorbidities, older patients have similar rates of postoperative complications and report similar outcomes for pain, function, and mobility following first MTP arthrodesis. These findings support increased implementation of MTP arthrodesis surgery for older patients with hallux rigidus.

Introduction/Purpose:

Talar neck fractures are uncommon and are characterized by displacement, comminution, and soft tissue injury. Treatment of talar neck fractures while avoiding complications, such as osteonecrosis and long-term morbidity, presents a unique challenge to surgeons. One option for treating talar neck fractures is cellular bone allograft containing viable lineage- committed bone cells (V-CBA), which provides the osteoconductive, osteoinductive, and osteogenic properties needed for bone formation. Additionally, a structural textured allograft (STA) wedge designed to resist migration and sustain compressive force can also be used in repairing talar neck fractures. This case study describes the successful repair of a comminuted talar neck fracture using V-CBA combined with an STA wedge.

Methods:

A 46-year-old male patient sustained a talar neck fracture following a fall from a 12-foot ladder. Radiographic and computed tomography (CT) imaging revealed significant comminution, consequent varus angulation, and a large bony void, as well as dislocation of the posterior subtalar joint. The patient was otherwise healthy with no comorbidities. Open reduction internal fixation was performed laterally to reduce the posterior subtalar dislocation. Medially, a 6.5mm STA wedge was used to correct the varus deformity and 1cc of V-CBA was used to fill the void.

Results:

At 6 months, the talar neck fracture had healed with solid osseous consolidation evident on radiographic images.

Conclusion:

These results demonstrate that an STA wedge, with a textured design that resists migration, used in combination with a V-CBA successfully repaired a comminuted talar neck fracture.

Introduction/Purpose:

Given that most ankle replacements are post-traumatic in origin, it is important to investigate if prior interventions can affect a patient’s functional outcome or the possibility of having a complication. Prior surgeries create scar, incisions, and possible affect bone health that could interfere with healing. The purpose of the study is to assess the pain and functional temporal outcomes of patients with and without prior surgeries in the ipsilateral ankle. We hypothesize that those with a previous ipsilateral ankle procedure will not have an increased complication rate or worse functional outcomes.

Methods:

We retrospectively identified a consecutive series of 100 primary TARs with a prior procedure who were followed for a minimum of 3 years. The follow-up time points considered were 0, 6, 12, and 36 months. Outcomes were measured using AOFAS, VAS, SF12, and range of motion scores. The mean patient age was 56.5 +- 13.4 years. Sixty-four patients had previous interventions which included osteosynthesis (49), arthroscopy (11), hardware removal (25), arthrodesis (3), prosthesis (1), open fracture (9), and other open surgery (12). Within-group comparisons were performed using one-way repeated-measures ANOVA (1-w rANOVA), analyzing temporal course of clinical data (comparisons between different time points) between the groups. To compare the time course of clinical measures between the two groups, 2-w rANOVAs were performed. Data and statistical analysis were conducted using Matlab (MathWorks, Natick, MA).

Results:

For each type of intervention, every outcome was compared to test whether presurgery interventions have an influence on the temporal evolution of the outcomes. The two groups did not show any difference on the temporal evolution of the outcomes. The type of intervention did have a weak effect on outcomes. Treatment of previous open fractures was the only pre- surgical intervention that showed a statistically significant difference in temporal evolution of functional and pain outcomes between intervention and non-intervention groups. No significant correlations were found between all outcomes and the time between the last intervention and prosthesis. Using Fisher’s-exact test, there was not a significant association between the those who had previous surgery and those who did not and the rate of complication and revision (p =0.10).

Conclusion:

A pre-operative discussion should center on potential complications and predicted functional outcomes. The presence, type, and timing of an intervention prior to an ankle replacement does not strongly affect the temporal outcomes of pain and functional outcome scores. Furthermore, the complication or revision rate is not affected by prior surgeries.

Arthroscopy; Trauma

Introduction/Purpose:

The treatment of posterior malleolar fractures within a trimalleolar ankle fracture pattern can be challenging to manage. Due to anatomical constraints that inhibit visualization of the articular surface, reduction of the posterior malleolus relies on cortical read and/or intraoperative fluoroscopy. Posterior ankle arthroscopy is a tool that may address this shortfall by providing a means to assess the intra-articular and syndesmotic reductions, while removing any loose bodies. The purpose of this study was to determine the radiographic and patient reported outcomes of posterior arthroscopic reduction and internal fixation (PARIF) for the posterior malleolar fragment in trimalleolar ankle fractures.

Methods:

From November 2015 to May 2019, we prospectively enrolled consecutive trimalleolar ankle fractures that underwent PARIF for the posterior malleolar fragment by a single surgeon. Patient demographics, surgical details, and fracture characteristics, as determined by computed tomography (CT) scan, were obtained. At final follow-up the main outcome measures collected were: The Foot and Ankle Disability Index (FADI), American Orthopaedic Foot & Ankle Society (AOFAS) ankle score, Olerud and Molander Ankle Score (OSMA), the Visual Analog Score (VAS), and surgical complications. Preoperative and postoperative CT scans were interpreted and compared by two blinded musculoskeletal radiologists for articular congruity, syndesmosis congruity, and presence of loose bodies.

Results:

A total of 29 trimalleolar ankle fractures were treated with PARIF, including 15 fracture-dislocations. Mean patient age was 36 (range, 19-69) years. Mean prone tourniquet time was 58 (range, 35-79) minutes. Preoperative CT scans demonstrated intra-articular loose bodies in 53% of fractures and syndesmosis incongruity in 80% of fractures. Postoperative CT scans showed one ankle with a retained loose body and residual syndesmosis incongruity in 17% of fractures. 100% of fractures healed and demonstrated intra-articular reduction within 2mm. There were 2 complications (hardware irritation and sural nerve numbness). 2-year patient reported outcomes were available in 13 patients. These included mean VAS 1 (range 0-4), mean AOFAS score 84 (range, 63-100), mean FADI 85 (range, 59-100), and mean OSMA 76 (range, 40-100).

Conclusion:

Posterior ankle arthroscopic reduction and internal fixation (PARIF) is a safe and effective option for management of posterior malleolar fractures. The technique results in improved intra-articular and syndesmosis congruity, while removing loose bodies. Future studies are needed that compare this technique with current practices.

Introduction/Purpose:

The establishment of the Open Payments Database (OPD) in 2014 made public all financial payments to physicians and hospitals by pharmaceutical and medical device companies. Since then, numerous studies have analyzed industry payment data to elucidate any correlations and trends. The purpose of this study is to examine trends in industry payments to orthopedic foot and ankle surgeons from 2014 to 2018.

Methods:

The Open Payments Database (OPD) was queried to collect information regarding industry payments to orthopedic foot and ankle surgeons and all orthopedic surgeons from 2014 to 2018. Information was collected on physician education, regional distribution of physicians paid, number of physicians paid, median payment amount, and payment type. Further analyses were conducted on the median payment amount to the top 5% of earners and the other 95%. Median amounts were analyzed using Mann-Whitney U non-parametric tests.

Results:

Of the 1,416 physicians classified as orthopedic foot and ankle surgeons, Doctors of Osteopathy and Medical Doctors received significantly higher payments than Doctors of Podiatric Medicine (597 vs. 35, P=9x10-113). Only osteopathic and allopathic physicians were included in the main analyses. No significant difference was reported from 2014 to 2018 in the median payments to orthopedic foot and ankle surgeons overall ($616 vs. $810; P=0.13), in the top 5% ($148,864 vs. $158,349; P=0.53), and other 95% ($542 vs. $730; P=0.10). There was no significant difference in payments related to consulting fees, entertainment, food and beverages, gifts, grants, honoraria, royalty and licensing fees, speaker and faculty fees, and travel and lodging. There was a significant increase in industry payments related to education ($750 vs. $1370; P=0.002).

Conclusion:

Following the establishment of the Open Payments Database in 2014, it was expected that industry payments would decrease significantly. However, no change was seen in payments to orthopedic foot and ankle surgeons and there remains a very large distribution in surgeon compensation. In fact, the top 5% of surgeons compensated account for over 99% of the total industry payments. While there are many factors that could account for this, foot and ankle surgeons should use data extracted from the OPD as a guide to ensure fair and equitable compensation for their work in industry.

Hindfoot; Midfoot/Forefoot

Introduction/Purpose:

Adult acquired flatfoot deformity is a complex deformity associated with the collapse of the medial longitudinal arch. Several factors have been proposed in the etiology of adult acquired flatfoot deformity including arthritic, neuromuscular, and traumatic conditions; however, posterior tibial tendon dysfunction remains the most common etiology. A spectrum of conditions affecting the posterior tibial tendon has been identified, with tendinitis occurring early in the disease process and tendon rupture occurring at the more advanced stages. Adult-acquired flatfoot deformity requires a complex operative plan that often utilizes several procedures to correct deformity, at both the hindfoot and midfoot. The objective of this study was to compare the efficacy of two different osteotomies commonly used to correct flexible flat feet.

Methods:

42 Patients (21 males and 21 females) with stage II PTTD acquired flexible flatfeet were included with a mean age of 49.62 +- 6.2. Twinty-two patients had medial displacement calcaneal osteotomy (MDCO) while 20 cases had latercal column lenghtening (LCL). Strayer procedure, spring ligament plication and FDL transfer were done in all patients. Pre- and Post-operative clinical assessment was done using AOFAS and FFI questionaire. Six radiographic parameters were analyzed, two in the anteroposterior view ( talo-navicular coverage and talo-calcaneal angle), three in lateral view ( talo- first metatarsus angle, talo- calcaneal angle and calcaneal inclination angle) and tibio-calcanal angle in axial view.

Results:

At a mean follow up of 12 months, significant improvement in AOFAS and FFI scores in MDCO and LCL groups with no significant difference between both groups. Postoperative significant improvements in all radiographic measurements in both groups. LCL group showed significant better correction in TNC and calcaneal inclination angles when compared to MDCO group. However, MDCO procedure showed significantly better correction in axial tibial calcaneal angle. Both techniques correct the deformity, however cases received LCL has better correction than MDCO cases and less reoperation rate.

Conclusion:

Reconstructions performed with LCL produced a greater change in the realignment of adult acquired flatfoot, maintained more of their initial correction over time, and were associated with a lower incidence of additional surgery than reconstructions with a MDCO of the calcaneus. However, a higher incidence of degenerative change in the hindfoot was observed in the LCL group. The ability of LCL to correct the deformity in anteroposterior and lateral plan and MDCO in lateral and axial plan suggests that proper osteotomy should be planned according to the existing deformity. Combination of both techniques may be required in certain cases.
