Non-Union Treatment in the Foot, Ankle, and Lower Leg: A Multicenter Retrospective Study Comparing Conventional Treatment with the Human Allogeneic Cortical Bone Screw (Shark Screw ®). J Pers Med 2024; 14:352. [PMID: 38672979 PMCID: PMC11051244 DOI: 10.3390/jpm14040352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 03/20/2024] [Accepted: 03/25/2024] [Indexed: 04/28/2024] Open
Abstract
Addressing non-unions involves stabilizing the affected area through osteosynthesis and improving bone biology using bone grafts. However, there is no consensus on the optimal treatment method. This study aims to compare outcomes of non-union surgery using conventional treatment methods (metal hardware ± graft) versus osteosynthesis with the human allogeneic cortical bone screw (Shark Screw®) alone or in combination with a metallic plate. Thirty-four patients underwent conventional treatment, while twenty-eight cases received one or more Shark Screws®. Patient demographics, bone healing, time to bone healing, and complications were assessed. Results revealed a healing rate of 96.4% for the Shark Screw® group, compared to 82.3% for the conventionally treated group. The Shark Screw® group exhibited a tendency for faster bone healing (9.4 ± 3.2 vs. 12.9 ± 8.5 weeks, p = 0.05061). Hardware irritations led to six metal removals in the conventional group versus two in the Shark Screw® group. The Shark Screw® emerges as a promising option for personalized non-union treatment in the foot, ankle, and select lower leg cases, facilitating effective osteosynthesis and grafting within a single construct and promoting high union rates, low complications, and a rapid healing process.

Abstract
BACKGROUND The purpose of this study is to use three-dimensional finite-element analysis to better understand the biomechanical features of various internal fixators for ankle arthrodesis. METHODS We used finite-element analysis to compare four different types of internal fixations in ankle arthrodesis: Group A had three crossed screws (Ø6.5 mm); Group B had two crossed screws (Ø6.5 mm) and an anterior plate (Ø2.7 mm); Group C only had an anterior anatomical plate (Ø3.5 mm); Group D had one anterior anatomical plate (Ø3.5 mm) and one posterior-lateral screw (Ø6.5 mm). We adopted Ansys 21.0 software to analyze and compare the four types in terms of the displacement of the arthrodesis surface and the stress peak and stress distribution of these models under intorsion, extorsion, dorsiflexion torque, and neutral vertical load. RESULTS ① Displacement of the arthrodesis surface: In Group A, the maximum displacement was larger than Group D under neutral vertical load and dorsiflexion torque but less than it under intorsion and extorsion torque. In Group B, the maximum displacement against dorsiflexion, neutral vertical load, intorsion, and extorsion was less than that in the other three fixation models. In Group C, the maximum displacement against the above four loading patterns were significantly higher than that in another three fixation models. ② Stress peak and stress distribution: based on the stress distribution of the four models, the peak von Mises stress was concentrated in the central sections of the compression screws, plate joints, and bending parts of the plates. CONCLUSIONS The fixation model consisting of two crossed screws and an anterior outperformed the other three fixation models in terms of biomedical advantages; thus, this model can be deemed a safe and reliable internal fixation approach for ankle arthrodesis.

Abstract
Joint destruction necessitates tibiotalocalcaneal arthrodesis (TTCA) in cases of clinical deficits that cannot be controlled conservatively, possibly leading to sepsis. We aimed to compare the underlying etiology of posttraumatic joint destruction and the outcomes after TTCA in patients with a septic or aseptic history. Between 2010 and 2022, 216 patients with TTCA were retrospectively enrolled (septic TTCA (S-TTCA) = 129; aseptic TTCA (A-TTCA) = 87). Patient demographics, etiology, Olerud and Molander Ankle Scores (OMASs), Foot Function Index (FFI-D) scores, and Short Form-12 Questionnaire (SF-12) scores were recorded. The mean follow-up period was 6.5 years. Tibial plafond and ankle fractures were the most common causes of sepsis. The mean OMAS was 43.0; the mean FFI-D was 76.7; and the mean SF-12 physical component summary score was 35.5. All the scores differed significantly between the groups (p < 0.001). With an average of 11 operations until the arthrodesis was achieved, the S-TTCA patients underwent about three times as many operations as the A-TTCA patients (p < 0.001), and 41% of S-TTCA patients remained permanently unable to work (p < 0.001). The significantly worse results of S-TTCA compared to A-TTCA show the long and stressful ordeal that patients with a septic history suffer. Further attention must be paid to infection prophylaxis and, if necessary, early infection revision.

Abstract
Posttraumatic osteoarthritis may lead to surgical fusion of the ankle joint if non-surgical therapy fails. The indication for a fusion of the joint is based on the pain and disability of the patient, radiographic imaging, and surgeon experience, with no strict guidelines. We aimed to compare outcomes after tibiotalocalcaneal arthrodesis (TTCA) and tibiotalar arthrodesis (TTA) to highlight the functional importance of the subtalar joint. In total, 432 patients with ankle arthrodesis were retrospectively enrolled. Group A (n = 216) underwent TTCA; group B (n = 216) underwent TTA. Demographics, Olerud & Molander Ankle Score (OMAS), Foot Function Index (FFI-D), and Short Form-12 Questionnaire (SF-12) were recorded at a mean follow-up of 6.2 years. The mean OMAS was 50.7; the mean FFI-D was 68.9; the mean SF-12 physical component summary was 39.1. These scores differed significantly between the groups (p < 0.001). The overall revision rate was 18%, primarily for revision of non-union and infection (p < 0.001). Approximately 16% of group A and 26% of group B were able to return to previous work (p < 0.001). Based on significantly worse clinical scores of TTCA compared to TTA and the prolonged downtime and permanent incapacity, the indication for a generous subtalar joint arthrodesis with planned ankle arthrodesis should always be critically examined.

Abstract
While adjacent joint arthritis is a recognized long-term downside of primary tibiotalar arthrodesis (TTA), few studies have identified risk factors for early subtalar arthrodesis (STA) after TTA. This study aims to identify the risk factors for STA within the first few years following TTA. All patients older than 18 years undergoing TTA between 2008 and 2016 were identified retrospectively. Demographic data and comorbidities were collected alongside prior operative procedures, postoperative complications, and subsequent STA. Pre-and postoperative Kellgren-Lawrence osteoarthritis grade of the subtalar joint and postoperative radiographic alignment were obtained. A total of 240 patients who underwent primary TTA were included in this study with median follow up of 13.8 months. Twenty patients (8.3%) underwent STA after TTA due to symptomatic nonunion of TTA in 13 (65%), progression of symptomatic subtalar osteoarthritis (OA) in 4 (20%), and symptomatic nonunion of primary TTA combined progressively symptomatic subtalar OA in 2 (10%). Preoperative radiographic subtalar OA severity and postoperative radiographic alignment were not correlated with subsequent STA. Diabetes mellitus, Charcot arthropathy, neuropathy, alcohol use, substance use disorder, and psychiatric disease were significantly associated with having a subsequent STA. The most common postoperative contributing factor for subsequent STA following primary TTA was the salvage of symptomatic ankle nonunion rather than subtalar joint disease. Patients considering an ankle fusion should be counseled of the risk of subsequent STA, especially if they have risk factors that include diabetes, Charcot arthropathy, neuropathy, alcohol use, substance use disorder, or psychiatric disease.

Abstract
Connolly recognized as early as 1998 that a displaced ankle fracture in a neuropathic diabetic puts that patient at risk for an amputation. It is well appreciated that the risk of a poor clinical outcome secondary to failure of the surgical construct, deep wound infection and osteomyelitis or a combination of both, is greatly increased in neuropathic diabetic patients, that is, those that are insensate to the Semmes-Weinstein 5.07 (10 g) monofilament, as compared with sensate diabetics or similar non-diabetic patients. Despite this understanding, there is little objective evidence to guide treatment. The goal of this monograph is to provide the practicing Orthopaedic Surgeon the best consensus expert opinion and the most current new innovations to optimize clinical outcomes and avoid complications in this highly co-morbid patient cohort.

Does Demineralized Bone Matrix Affect the Nonunion Rate in Arthroscopic Ankle Arthrodesis? J Clin Med 2022; 11:jcm11133893.

Abstract
Demineralized bone matrix (DBM) has been shown to have positive effects on union rates in many orthopedic subspecialties; however, minimal evidence exists about bone graft substitutes in foot and ankle surgery. The purpose of this study is to compare nonunion rates in arthroscopic ankle arthrodesis in patients receiving DBM with those without. We hypothesized DBM to be associated with a decreased risk of nonunion. This retrospective review includes 516 consecutive ankle arthrodesis cases from March 2002 to May 2016. Of these, 58 ankles (56 patients) that underwent primary arthroscopic ankle arthrodesis met the inclusion criteria, and 31 of these ankles received DBM, while 27 did not. Nonunion was assessed by clinical examination and routine postoperative radiographs. If nonunion was suspected, a computed tomography (CT) scan was performed. The primary outcome measure was nonunion rate. Secondary outcome measures included wound complications, return to operating room (OR), and rate of postoperative deep vein thrombosis (DVT) or pulmonary embolism (PE). From the study cases, 58 were available for final follow-up. The average age was 55.9 years (±17.4), and mean follow-up was 43.0 months (range 6.3–119.4). There was no difference in nonunion rate in patients who received DBM (4/31, 12.9%) versus those who did not (4/27, 14.8%) (p = 0.83). Similarly, when comparing the two groups, there were no statistically significant differences in superficial wound complications (6.5% vs. 3.7%, p = 1.0) or rate of return to OR (29% or 0.037/person-years vs. 37% or 0.099/person-years; p = 0.20). No major complications including deep wound infections, DVTs, or PEs occurred. This is the largest study to directly compare nonunion rates and complications for patients receiving DBM versus those who did not in primary arthroscopic ankle arthrodesis. No significant association was found between DBM usage and risk of nonunion, wound complications, return to OR, or postoperative DVT or PE development.

Abstract
Open ankle arthrodesis remains a reliable solution for ankle arthritis, especially in the setting of deformity. Careful preoperative evaluation needs to be performed, both clinically and radiographically. The specific deformity present helps determine the approach used and the fixation choices. Deformity is most commonly seen intraarticularly, though deformity can also be present anywhere along the lower extremity, including compensatory deformity in the foot. Multiple different techniques can be used to address both the deformity and achieve a successful ankle arthrodesis. Patient outcomes reported in the literature are generally good, with high union rates and improved functional outcomes.

Abstract
After isolated ankle (tibiotalar) arthrodesis, the triceps progressively shifts the subtalar joint into varus thus blocking compensatory motion from the midtarsal joints. In a tibiotalocalcaneal arthrodesis, the subtalar may be fixed with the correct valgus. Comparison between ankle and tibiotalocalcaneal arthrodesis does not clearly favor one over another for pain relief, satisfaction, and gait analysis. Compensatory sagittal plane motion through the midtarsal joints when the subtalar is fixed in valgus may be responsible for these results. Tibiotalocalcaneal arthrodesis has become our procedure of choice over isolated tibiotalar for end-stage ankle arthritis regardless of the radiographic state of the subtalar.

Abstract
Ankle arthrodesis (AA) provides reliable pain relief, good patient satisfaction scores, and improved overall function. However, this procedure has been associated with numerous complications and sequelae, such as pseudoarthrosis, malunion, gait abnormalities, increased demand on surrounding joints, and a long period of convalescence. Conversion to total ankle arthroplasty (TAA) is a potential option in the management of these complex and challenging situations. The purpose of this study is to investigate the outcomes of AA conversion to TAA. A systematic review of electronic databases was performed. Six studies involving 172 ankles met inclusion criteria. The weighted mean preoperative Visual Analogue Scale (VAS) score at the time of TAA conversion was 7.8 and the weighted mean postoperative VAS score at the time of final follow-up was 2.5. The weighted mean preoperative AOFAS score at the time of TAA conversion was 32 and the weighted mean postoperative AOFAS score at the time of final follow-up was 72.4. The rate of salvage tibiotalocalcaneal arthrodesis was 2.3% and rate of transtibial amputation was also 2.3% after attempted conversion from initial AA to TAA. Conversion of AA to TAA appears to be a viable option to improve patient outcomes and prevent extensive hindfoot arthrodesis and transtibial amputation. More prospective studies with consistent reporting of outcomes, complications, and revision rates with long-term follow-up are needed.

Abstract
BACKGROUND Tibiotalar and subtalar arthritis requiring tibiotalocalcaneal (TTC) fusion can be technically challenging and is dependent on reliable fusion for a good clinical outcome. Initial data regarding bone marrow aspirate concentrate (BMAC) has shown promise in use as an aide in both fracture and fusion healing. The purpose of this study is to determine the outcomes in TTC fusion when utilizing BMAC as an adjunct. METHODS Twenty consecutive patients who underwent TTC fusion with BMAC adjunct between March 2013 and November 2017 were retrospectively screened for inclusion. Patients were included regardless of comorbidities or risk factors for non-union, and only excluded if they did not have a minimum of 12 months of clinical and/or radiographic chart data. Follow-up was obtained at regular intervals of 6 weeks, 3 months, 6 months and 1 year. Modified RUST scores were applied to grade bony union in a blinded fashion by two orthopedic trauma fellowship-trained surgeons and agreement was assessed via intraclass correlation coefficient (ICC). RESULTS Twenty patients were screened and 12 met inclusion criteria for analysis. Majority were male (66.6%) at a mean age of 55.4 years and they were all treated via TTC fusion for a diagnosis of tibiotalar and subtalar arthritis. There were no postoperative complications and no reoperations in this cohort; no donor site morbidity was associated with BMAC. By the 3-month follow-up timepoint, all but one patient received a minimum modified RUST score of 10 indicating bony union (ICC 0.91); by the 6-month time point (ICC 0.94), all 12 patients were deemed united. CONCLUSION BMAC as an adjunct in the setting of TTC fusion is a safe treatment option that can promote reliable, consistent bony fusion with minimal complications.

Abstract
INTRODUCTION Non-union is a regular complication of arthrodeses. Standard treatment includes revision surgery with frequent need for re-revision due to persistent non-union. Particularly patients with concomitant diseases are at risk of secondary complications. There is a need for evaluation of alternative treatment options. The aim of this study is to provide first evidence on union-rate and pain course after focussed extracorporeal shock-wave therapy of arthrodesis non-unions. PATIENTS AND METHODS In a retrospective single-centre study, 25 patients with non-union following arthrodesis received one session of focussed extracorporeal shock-wave therapy (energy flux density 0.36 mJ/mm2, 3000 impulses, 23 kV, 4 Hz). Radiographic and clinical results were recorded 6, 12 and 24 weeks after treatment. RESULTS 24 patients were followed-up. After 24 weeks arthrodeses of the hand healed in 80%, of the upper ankle in 50%, of subtalar joint in 27.2% and of the midfoot in 0% of the cases. Pain decreased from 4.8 (± 2.8) points on the visual analogue scale to 3.4 (± 2.3), 2.9 (± 2.5) and 2.4 (± 2.8) points after 6, 12 and 24 weeks, respectively (p < 0.0001). CONCLUSION Our data indicate that the effect of focussed, high-energy shock wave therapy depends on body region and is effective for the treatment of non-unions of the hand as well as for pain relief.

Abstract
Background: Tibiotalocalcaneal (TTC) arthrodesis implementing adjunctive allografts is a method of limb salvage for patients with complex hindfoot osseous deficits, though outcome results are limited. The purposes of this study were to assess functional and radiographic outcomes after TTC arthrodesis with femoral head allograft and retrospectively identify prognostic factors. Methods: The authors reviewed 24 TTC arthrodesis procedures with bulk femoral head allografts performed by a single surgeon from 2004 to 2016. Radiographic union at the ankle and subtalar joints along with stability of the allograft were assessed. Patients who had clinically successful arthrodeses were contacted to score the Foot and Ankle Ability Measure-Activities of Daily Living (FAAM-ADL) questionnaire, Visual Analog Scale (VAS) for pain, and Short Form-12 (SF-12) at a mean of 58.0 months (range, 28-102) postoperatively. Results: Complete radiographic union of involved joints was achieved in 15 patients (63%) and in 75% (36/48) of all joints; 21 ankles (88%) were assessed to be radiographically stable at final follow-up. Three patients (13%) underwent revision arthrodesis at a mean of 18.9 months postoperatively, and 21 patients (88%) did not require additional surgery as of final follow-up. Patients significantly improved to a mean FAAM-ADL score of 71.5 from 36.3 (P < .001). The mean VAS for pain significantly improved from 77.2 to 32.9 (P < .001). Male sex (P = .08) and a lateral operative approach (P = .03) both resulted in worse outcomes. Conclusion: Use of a femoral head allograft with TTC arthrodesis can offer improved functional scores and sustained radiographic outcomes.Level of Evidence: Level IV: Case series.

Abstract
Background. Tibiotalocalcaneal (TTC) arthrodesis is a common treatment option for hindfoot arthritis and deformity. Loss of compression over time with statically locked nails may contribute to nonunion. A novel retrograde intramedullary nail with an internal pseudoelastic component has recently been used to provide sustained dynamic compression (SDC). The purpose of this study was to compare fusion rates and time to union between the SDC and nondynamized (ND) nails. Methods. All patients who underwent TTC arthrodesis with an intramedullary nail at a single institution from 2013 to 2017 and who had at least 1 year of follow-up were included in this study. Baseline patient and operative characteristics were collected and compared between the sustained SDC and ND nail groups. The rate of successful fusion, time to union, and complications were compared between the groups. Results. The SDC cohort had a significantly faster time to union by 3.9 months (P = .049). The SDC cohort had a higher fusion rate (78.0%) compared with the ND nail cohort (75.0%), although this was not statistically significant (P = .75). The SDC nail was used significantly (P < .05) more often in patients with known risk factors for nonunion, including female sex, smoking, revision surgery, prior trauma, and patients requiring 3D cage implants for significant bone loss. There were no differences between the groups in terms of complications. Conclusion. The SDC nail has been shown to achieve successful arthrodesis in a population at high risk for nonunion, using less hardware, and at a faster rate than ND nails. Level of Evidence: Level III: Retrospective, comparative study.

Abstract
BACKGROUND Arthrodesis of the ankle is a salvage procedure in case of chronic ankle joint infection. External fixation still is the gold standard. We compared the outcome of external fixator versus intramedullary nailing for arthrodesis of the infected ankle joint. METHODS All patients with ankle joint infection who received arthrodesis with either external fixator or intramedullary nail between 08/2009 and 09/2017 were retrospectively analyzed. Endpoints were the successful control of infection, osseous fusion, and mobilization with full weightbearing. RESULTS Seventy-one patients were included. Nineteen patients (27%) suffered reinfection. Patients with intramedullary nailing showed significantly fewer reinfections (p=0.019), achieved full weightbearing significantly more often (p=0.042) and faster and developed significantly fewer complications (p<0.001). Forty-three patients showed bone fusion without significant differences between the groups. CONCLUSIONS Ankle arthrodesis with intramedullary nailing appears to be a successful alternative to the established procedure of external fixation in cases of chronic ankle joint infection.

Abstract
Between January 1, 2011, and January 1, 2017, an orthopaedic foot and ankle surgeon performed tibiotalar arthrodesis on 221 patients. Thirty-two were included in this study. Inclusion criteria included patients with at least one risk factor for nonunion and/or malunion, isolated anterior ankle arthrodesis with plate fixation, patients older than 18, and a minimum of 1-year follow-up. Risk factors were avascular necrosis of the talus, severe segmental bone defect, smoking, inflammatory arthropathy, coronal deformity greater than 15°, diabetes mellitus, septic nonunion, failed ankle arthrodesis, and body mass index greater than 35. Functional outcome questionnaires (Ankle Osteoarthritis Score [AOS] and Foot Function Index [FFI]) were collected at the latest visit or by phone. Twenty-six (26/32, 81.2%) patients included in the study had computed tomography images available for review at an average of 3.2 months after surgery. The rate of successful arthrodesis was 93.8% (30/32) at an average of 78 days. Overall, 14 patients (14/32, 43.8%) developed a postoperative complication, including 1 patient that had a delayed nonunion and 2 patients that proceeded to nonunion. Twenty-three patients (23/32, 71.9%) completed the functional outcome questionnaires at an average of 26.8 months. Mean AOS and FFI scores improved significantly postoperatively (P < .001). Sagittal tibiotalar and coronal tibiotalar alignment improved significantly in patients with severe preoperative deformity (P < .001). Tibiotalar arthrodesis with anterior plate fixation in a high-risk cohort results in high union rates and significantly improved functional outcomes. Levels of Evidence: Therapeutic, Level IV: Prospective, comparative trial.

Abstract
BACKGROUND Tibiotalar arthrodesis is a common treatment for end-stage tibiotalar osteoarthritis, and is associated with a long-term risk of concomitant subtalar osteoarthritis. It has been clinically hypothesized that subtalar osteoarthritis following tibiotalar arthrodesis is the product of compensatory subtalar joint hypermobility. However, in vivo measurements of subtalar joint motion following tibiotalar arthrodesis have not been quantified. Using dual-fluoroscopy motion capture, we tested the hypothesis that the subtalar joint of the limb with a tibiotalar arthrodesis would demonstrate differences in kinematics and increased range of motion compared with the subtalar joint of the contralateral, asymptomatic, untreated ankle. METHODS Ten asymptomatic patients who had undergone unilateral tibiotalar arthrodesis at a mean (and standard deviation) of 4.0 ± 1.8 years previously were evaluated during overground walking and a double heel-rise task. The evaluation involved markerless tracking with use of dual fluoroscopy integrated with 3-dimensional computed tomography, which allowed for dynamic measurements of subtalar and tibiotalar dorsiflexion-plantar flexion, inversion-eversion, and internal-external rotation. Range of motion, stance time, swing time, step length, and step width were also measured. RESULTS During the early stance phase of walking, the subtalar joint of the limb that had been treated with arthrodesis was plantar flexed (-4.7° ± 3.3°), whereas the subtalar joint of the untreated limb was dorsiflexed (4.6° ± 2.2°). Also, during the early stance phase of walking, eversion of the subtalar joint of the surgically treated limb (0.2° ± 2.3°) was less than that of the untreated limb (4.5° ± 3.2°). During double heel-rise, the treated limb exhibited increased peak subtalar plantar flexion (-7.1° ± 4.1°) compared with the untreated limb (0.2° ± 1.8°). CONCLUSIONS A significant increase in subtalar joint plantar flexion was found to be a primary compensation during overground walking and a double heel-rise activity following tibiotalar arthrodesis. CLINICAL RELEVANCE Significant subtalar joint plantar flexion compensations appear to occur following tibiotalar arthrodesis. We found an increase in subtalar plantar flexion and considered the potential relationship of this finding with the increased rate of subtalar osteoarthritis that occurs following ankle arthrodesis.

Abstract
The definition of consolidation after ankle arthrodesis can be challenging in some situations. Computed tomography has increased diagnostic accuracy; however, there are still no clear criteria for nonunion. In this context, arthroscopy with direct visualization of the arthrodesis may provide crucial data to inform the choice of treatment. The present report illustrates a case in which arthroscopy prompted a change in treatment strategy. More extensive surgery, with the potential for greater morbidity due to revision arthrodesis, could be avoided.

Abstract
BACKGROUND With longer follow-up, survival rate of total ankle replacements (TAR) diminishes. It is therefore important to have a reliable fall-back option in case of failed TAR. Revision arthroplasty is often impossible because of loss of bonestock or infection. Conversion to ankle fusion is then indicated. We investigated the clinical, radiographic and patient reported results for fusion after failed TAR in a consecutive group of patients. We concentrated on the influence of inflammatory joint disease (IJD) on union rate. METHODS Patient files and radiographic images of 46 consecutive patients (47 ankles) were reviewed. There were 22 patients with IJD. Fixation methods included; anterior plating, blade plate fixation, intramedullary nailing, compression screws and external fixation. Foot and Ankle Outcome Score (FAOS) and Foot and Ankle Ability Measure (FAAM) were used to determine patient related outcomes. RESULTS Forty out of 47 ankles (85%) Fused. Union rate in the non-IJD group (96%) was significantly higher compared to the IJD-group (73%, p=0.04). Revisions and complications were more frequent in the IJD group, but numbers were too small to detect a significant difference. Mean PROM scores were: FAOS-symptoms; 68.5, FAOS-pain; 70.3, FAOS-QoL; 43.7, FAOS-ADL; 68.1 and FAAM-ADL; 52.1, with no significant difference between IJD and non-IJD patients. CONCLUSIONS IJD-patients have a higher nonunion rate after ankle fusion for failed TAR. However, patient reported outcome is not significantly different between the two groups.

Abstract
BACKGROUND Osteochondral allograft (OCA) transplantation is a useful treatment for posttraumatic ankle arthritis in young patients, but failure rates are high and reoperations are not uncommon. The aim of this study was to evaluate the outcomes of failed ankle OCA transplantation converted to ankle arthrodesis (AA) or total ankle arthroplasty (TAA). METHODS We evaluated 24 patients who underwent salvage procedures (13 AA and 11 TAA) after primary failed ankle OCA transplantation. Reoperations were assessed. Failure of the salvage procedure was defined as an additional surgery that required a revision AA/TAA or amputation. Evaluation among nonfailing ankles included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM), pain, and satisfaction. RESULTS In the salvage AA cohort, 3 patients were classified as failures (2 revision AA and 1 amputation). The 10 nonfailing patients had a mean follow-up of 7.4 years. Eighty-eight percent were satisfied with the procedure, but 63% reported continued problems with their ankle (eg, pain, swelling, stiffness). Mean pain level was 1.9 and AAOS-FAM core score was 83±13. In the salvage TAA cohort, 2 patients were classified as failures (both revision TAA). The 9 nonfailing patients had a mean follow-up of 3.8 years. Fifty percent were satisfied with the procedure, but 40% reported continued problems with their ankle. The mean pain level was 1.3, and the median AAOS-FAM core score was 82±26. CONCLUSION Revision and reoperation rates for salvage procedures following failed OCA transplantation of the ankle are higher compared to published data for primary AA and TAA procedures. However, we believe OCA transplantation can serve as an interim procedure for younger patients with advanced ankle joint disease who may not be ideal candidates for primary AA or TAA at the time of initial presentation.

Abstract
PURPOSE OF REVIEW Trauma is the principle cause of osteoarthritis in the ankle, which is associated with significant morbidity. This review highlights the current literature for the purpose of bringing the reader up-to-date on the management of posttraumatic ankle arthritis, describing treatment efficacy, indications, contraindications, and complications. RECENT FINDINGS Recent studies on osteoarthritis have demonstrated variability among anatomic locations regarding the mechanisms and rates of development for posttraumatic osteoarthritis, which are attributed to newly discovered biological differences intrinsic to each joint. Regarding surgical management of posttraumatic ankle arthritis, osteochondral allograft transplantation of the talus, and supramalleolar osteotomies have demonstrated promising results. Additionally, the outpatient setting was found to be appropriate for managing pain following total ankle arthroplasty, associated with low complication rates and no readmission. Management for posttraumatic ankle arthritis is generally progressive. Initial treatment entails nonpharmacologic options with surgery reserved for posttraumatic ankle arthritis refractory to conservative treatment. Patient demographics and lifestyles should be carefully considered when formulating a management strategy, as outcomes are dependent upon the satisfaction of each set of respective criteria. Ultimately, the management of posttraumatic ankle arthritis should be individualized to satisfy the needs and desires, which are specific to each patient.

Abstract
BACKGROUND Osteochondral allograft (OCA) transplantation is a useful alternative for treatment of posttraumatic ankle arthritis in young patients but has a relatively high failure rate and further procedures are often required. The purpose of this study was to evaluate outcomes of patients who underwent revision OCA transplantation of the ankle after failed primary OCA transplantation. METHODS Twenty patients underwent revision OCA transplantation of the ankle between 1988 and 2015. Mean age was 44 years, 55% (11 of 20) were female. The mean time from primary to revision OCA was 3.0 ± 1.7 years. All patients had a minimum follow-up of 2 years. Outcomes included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM) and questionnaires evaluating pain and satisfaction. Failure of the revision OCA was defined as a conversion to arthroplasty, arthrodesis, or amputation. RESULTS Ten of 20 ankles required further surgery, of which 30% (6 of 20) were considered OCA revision failures (4 arthrodeses, 1 arthroplasty, and 1 amputation). The mean time to failure was 6.7 (range, 0.6-13.1) years. Survivorship of the revision OCA was 84% at 5 years and 65% at 10 years. The 14 patients with grafts remaining in situ had an average follow-up of 10.3 years; mean AAOS-FAM Core Score was 70.5 (range, 42.3-99). Of the patients who answered the follow-up questions, 4 of 7 reported moderate to severe pain, and 5 of 12 were satisfied with the results of the procedure. CONCLUSION Although the results of revision ankle OCA transplantation are not inferior to primary OCA transplantation, the high rates of persistent pain, further surgery, and graft failure suggest that the indications for OCA as a revision procedure should be carefully evaluated, with proper patient selection. Considering the treatment alternatives, revising a failed OCA transplantation can be a useful treatment option, especially for young and active patients who wish to avoid arthrodesis or arthroplasty.

Abstract
INTRODUCTION We performed a systematic review of the published literature to characterize patient demographic, surgical techniques, and functional outcomes to elucidate the complication and revision rates following isolated tibiotalar arthrodesis with anatomically contoured anterior plating. METHODS A comprehensive literature search was performed. Inclusion criteria were peer-reviewed studies in English, after 1990, at least 10 patients, and reporting clinical outcomes following contoured anterior plating and with follow-up of at least 80% and 1 year. Primary outcomes were fusion rate, time to fusion, return to activities, satisfaction, and functional outcome scores. Complication rates, reoperation, and revision were also extracted. RESULTS Eight primary studies with 164 patients met the inclusion criteria. The average sample size was 21 ± 10.0 patients and average age was 49.2 years with 61.6% male. Posttraumatic arthritis (49.4%) was the most common operative indication, followed by primary osteoarthrosis (18.9%). The average follow-up was 21.1 months. At this time, 97.6% of patients went on to uneventful union at a weighted average time of 18.7 weeks postoperatively. AOFAS scores improved significantly ( P < .05). 25% complication rate was reported with wound complication (7.9%) and hardware irritation (6.7%) most common. Overall, 21.3% of patients underwent reoperation; 4 for revision arthrodesis following nonunion. CONCLUSION Isolated tibiotalar arthrodesis utilizing anatomically contoured anterior plating demonstrates excellent clinical and functional outcomes at short-term follow-up. Overall, 97.6% of patients went on to fusion and functional outcomes consistently improved following surgery. Furthermore, while one-quarter of patients experienced complications, wound complications were relatively uncommon and less than one-quarter of these required surgical intervention.

Abstract
Ankle arthrodesis remains one of the most definitive treatment options for end-stage arthritis, paralysis, posttraumatic and postinfectious conditions, failed total ankle arthroplasty, and severe deformities. The general aims of ankle arthrodesis are to decrease pain and instability, correct the accompanying deformity, and create a stable plantigrade foot. Several surgical approaches have been reported for ankle arthrodesis with internal fixation options. External fixation has also evolved for ankle arthrodesis in certain clinical scenarios. This article provides a comprehensive analysis of midterm to long-term outcomes for ankle arthrodesis using internal and/or external fixation each for elective and diabetic conditions.

Abstract
BACKGROUND The treatment of limb threatening trauma on the distal tibia or hindfoot often results in posttraumatic osteoarthritis requiring tibiotalocalcaneal (TTC) arthrodesis. The purpose of this study was to present a case series of patients undergoing various techniques of joint fusion after bone reconstruction and deformity correction as a salvage procedure. The study should help trauma surgeons making decisions in limb salvage and deformity correction in complex lower leg and foot injuries by presenting options and treatment strategies. PATIENTS AND METHODS Eight patients (4 male, 4 female) after TTC arthrodesis as a definitive procedure after polytrauma or monotrauma involving the distal tibia or hindfoot were the subject of this retrospective analysis. We included patients treated by external ring fixation (1 case), external fixation+wires (1 case), external fixation+screws (1 case) and intramedullary nailing (1 ante- and 5 retrograde; 1 bilateral, 4 unilateral). Initial trauma included open fractures, subtotal foot amputations and closed fractures with failed osteosynthesis and failed ankle joint replacement. Bone defects were treated with callus distraction or segment transport in 5 cases. Various angles were measured to assess foot deformities in the lateral radiographic view and clinical results were presented. RESULTS Independent, pain-free mobilisation with full weight bearing was achieved in all 8 patients. In terms of subjective outcome, all patients reported a highly satisfying result. Complete consolidation at the fusion site was achieved in 8 out of 9 cases with a high rate of adjacent joint arthritis. Angles measures in the lateral radiographs showed values typical for a pes cavus tendency. CONCLUSION Tibio-talo-calcaneal (TTC) arthrodesis is a viable treatment option for severe post traumatic arthritis and deformity of the ankle and subtalar joint. Despite bad bone quality retrograde intramedullary nailing does provide acceptable results providing stability, low invasiveness and low infection rate. Simultaneous TTC-fusion and tibial lengthening using the Ilizarov ring fixator may be necessary when the surgeon is confronted with large bone defects - often followed by a nailing after lengthening procedure. This study shows that limb preservation after limb threatening trauma with hindfoot injury and multiple fractures of the lower extremity is recommenced as the method of choice with reasonable clinical results.

Abstract
UNLABELLED Hindfoot (tibiotalocalcaneal or TTC) arthrodesis is commonly used to treat concomitant arthritis of the ankle and subtalar joints. Simultaneous fusion of both joints can be difficult to achieve especially in patients with impaired healing due to smoking, diabetes mellitus, or Charcot neuroarthropathy. Conventional intramedullary fixation devices allow for compression to be applied at the time of surgery, but this compression can be lost due to bone resorption or settling, leading to impaired healing. In contrast, the novel pseudoelastic intramedullary nail is designed to maintain compression at the arthrodesis sites throughout the healing process by the use of an internal pseudoelastic element. We present 2 cases of revision TTC arthrodesis using the pseudoelastic intramedullary nail. In the first case, an 80-year-old diabetic man with previous ankle and failed subtalar fusion with screws underwent revision TTC arthrodesis. In the second case, a 66-year-old man with Charcot neuroarthropathy and a failed TTC arthrodesis with a static intramedullary nail underwent revision tibiotalar arthrodesis. In both cases, computed tomography scan demonstrated successful union and patients were allowed full weight bearing by 3 months after surgery. These cases provide early evidence that sustained compression via an intramedullary nail can lead to rapid successful hindfoot fusion when standard approaches have failed.

Abstract
BACKGROUND Tibiotalocalcaneal arthrodesis is a salvage procedure for patients with complex disease of the ankle and subtalar joints. Despite the clinical efficacy and mechanical advantage of intramedullary nails, complications, such as nonunion, are common. It may be possible to sustain compression in the face of bone resorption and implant loosening over the course of healing using a novel pseudoelastic intramedullary nail with an internal nitinol element. METHODS We identified 15 patients with average age of 54.7 years (range, 28-75 years) who had undergone a tibiotalocalcaneal arthrodesis using a pseudoelastic intramedullary nail. Serial radiographs were used to determine the amount and rate of nitinol element migration over the first 3 postoperative months. RESULTS Postoperatively, there was at least 2.38 mm of nitinol element migration proximally with mean of 5.58 mm (± 1.38), (range, 2.38-8.11 mm). Average follow-up time was 195 days (± 106.3), (range, 89-490 days). On average, 86% of the total recovered distance took place within the first 39.7 days (±10.03). CONCLUSIONS The nitinol element recovers distance when stretched intraoperatively and maintains moderate compression in response to bone resorption. Further studies are needed to assess if this increased compression lends itself to higher fusion rates than traditional intramedullary nails. LEVELS OF EVIDENCE Therapeutic, Level IV: Case series.

Abstract
BACKGROUND Previous hindfoot surgeries present a unique challenge to hindfoot arthrodesis, as the patients may have multiple incisions around the hindfoot. In high-risk patients with compromised soft tissues, a posterior approach can provide an alternative for a fresh soft tissue plane for the surgery. The use of a blade plate construct is widely accepted; however, there are limited data supporting the use of a posterior approach. QUESTIONS/PURPOSES We asked (1) what proportion of patients treated with this technique achieved osseous union; (2) what complications were observed; (3) were any patient-demographic or health-related factors associated with the likelihood that a patient would have a complication develop? METHODS Between December 2001 and July 2014, 42 patients received a posterior blade plate. During the period in question, indications for hindfoot arthrodesis using posterior blade fixation were subtalar osteoarthritis below an ankle fusion, malunion or nonunion, failed tibiotalocalcaneal arthrodesis attributable to nonunion of the tibiotalar and/or subtalar joint; or tibiotalar and subtalar osteoarthritis in patients with impaired bone or soft tissue quality (particularly if the soft tissue problem was anterior). During that period, all patients who met those indications were treated with a posterior blade plate. Forty (95%) were included in this study, and two were lost to followup before the 1-year minimum required by the study. Demographics (age, gender, BMI, smoking status, and comorbidities) and surgical data (indication, previous treatment, and additional procedures) were analyzed. Of the 40 patients included, 27 (68%) were male and 13 (33%) were female, with a median of two previous hindfoot or ankle surgeries (range, 0-9 surgeries). The mean age of the patients was 56 ± 13 years. Followup averaged 47 ± 28 months (range, 14-137 months). Twenty-eight of 40 (70%) patients had a tibiotalocalcaneal arthrodesis as a primary (n = 6), primary staged (n = 10), revision (n = 9), or revision staged (n = 3) procedure. Eleven of 40 patients (28%) underwent ankle arthrodesis (primary n = 7, revision n = 4). One of the 40 patients (3%) underwent tibiotalocalcaneal arthrodesis for a failed total ankle arthroplasty. Weightbearing radiographs were used to assess fusion. Osseous fusion was defined as visible trabecular bridging on the lateral and AP ankle views within 6 postoperative months. Delayed union was defined as osseous fusion occurring between 6 and 12 months. Nonunion was defined as no visible trabecular bridging at the latest followup (longer than 12 months). Clinic and surgery notes were reviewed for complications. Univariate analysis was performed to compare patient groups: patients with solid union versus nonunion, and patients with versus without complications. RESULTS Twenty-nine of 40 (73%) patients had osseous fusion within 6 postoperative months. Four of 40 (10%) patients had a delayed union between 6 and 12 months, and seven of the 40 (18%) patients had nonunions, which occurred in the ankle (n = 3), subtalar (n = 3), or both (n = 1) joints. There were 26 complications observed: 18 (69%) were considered major and eight (31%) were minor. With the numbers available, we did not identify any demographic or surgical factors associated with complications, delayed union, or nonunion. CONCLUSIONS The proportion of patients treated with a posterior blade plate hindfoot fusion who had delayed union or nonunion is greater than that reported for patients in other series who underwent primary hindfoot arthrodesis with other approaches, and the proportion of patients who had complications develop is high. Further studies are needed to address alternative approaches to achieve hindfoot fusion in patients with complex hindfoot problems. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Introduction Although conversion of the painful ankle arthrodesis to total ankle arthroplasty remains controversial, this surgical modality has satisfactorily expanded the treatment armamentarium for addressing this pathology. Indications & Contraindications Step 1 Preoperative Preparation and Surgical Planning Preoperative preparation and planning is similar to that for a primary total ankle arthroplasty, and implants designed for primary arthroplasty can be used in most patients managed with conversion to total ankle replacement. Step 2 Patient Positioning Position the patient as for a primary total ankle replacement. Step 3 Remove Hardware and Insert Prophylactic Malleolar Screws Preserve exsanguination time by removing hardware prior to inflating the tourniquet. Step 4 Recreate the Tibiotalar Joint Recreate the native joint line, which can be relatively easy in selected patients and challenging in others. Step 5 Set the Optimal Talar Slope Set the optimal talar slope, which can be challenging, particularly when the ankle arthrodesis is malunited in equinus. Step 6 Recreate the Medial and Lateral Gutters Because the former medial and lateral articulations between the talus and the malleoli can be difficult to define, use careful surgical technique to avoid compromise of the malleoli and excessive talar resection. Step 7 Mobilize the Ankle and Use Bone Graft in Defects from Previous Hardware To avoid potential malleolar fractures, mobilize the ankle only after the prophylactic malleolar screws have been placed; the tibial and talar cuts, completed; the gutters, reestablished; all resected bone, removed; and scar tissue from the posterior aspect of the ankle, excised; thereafter, conversion total ankle arthroplasty is similar to a primary total ankle replacement, with the exception of potential bone defects where prior hardware was positioned. Step 8 Talar Preparation Perform the routine steps for primary total ankle arthroplasty, often ignoring bone defects from the ankle arthrodesis hardware, but plan to repair the defects with bone-grafting before implanting the final talar component. Step 9 Tibial Preparation and Definitive Components Perform tibial preparation in a manner similar to that used for primary total ankle arthroplasty. Results We performed 23 conversion total ankle arthroplasties in patients who had an ankle arthrodesis, including those with pain despite successful fusion and those with painful nonunions9.

Abstract
UNLABELLED Background Nonunion of an ankle arthrodesis is associated with significant pain and morbidity. Revision arthrodesis presents greater short-term morbidity and long-term sequelae. 1-6 Recent reports have demonstrated the feasibility of converting a symptomatic nonunion of an ankle arthrodesis to a total ankle arthroplasty.7-9 The objective of the present study was to evaluate the short-term outcome associated with take down of symptomatic nonunions of ankle arthrodeses and conversion to a fixed bearing, intramedullary total ankle arthroplasty. Methods Five patients with symptomatic, aseptic tibiotalar arthrodesis nonunions (average age, 62.2 years), who underwent conversion to a total ankle arthroplasty were retrospectively identified and assessed at a prospective office visit. Minimum follow-up was 12 months (average, 21.3 months). Clinical outcomes were assessed on the basis of the American Foot and Ankle Society (AOFAS) ankle-hindfoot score10 and the Foot Function Index.11,12 Radiographic analysis, patient satisfaction and pain levels were also evaluated. Results The average post-operative AOFAS ankle-hindfoot score was 82.6, while the FFI was 28.2%. The average clinical range of motion was 35 degrees. Visual analog scale (VAS) pain scores averaged 31.1 out of 100. Four out of the five patients were very satisfied or satisfied. Radiographically, the tibial and talar components were stable in all patients without evidence of loosening, migration, or subsidence. There were no complications requiring additional procedures. Conclusions Patients undergoing ankle arthrodesis that is complicated by an aseptic nonunion pose a difficult clinical problem. Conversion to a total ankle arthroplasty with a fixed bearing, intramedullary implant is a viable treatment option with reliable short-term results.

Abstract
End-stage arthritis of the tibiotalar joint is disabling and causes substantial functional impairment. Most often it is the residual effect of a previous traumatic injury. Nonsurgical treatment of end-stage arthritis of the ankle includes bracing, shoe-wear modifications, and selective joint injections. For patients who fail to respond to nonsurgical modalities, the two primary treatment options are arthroplasty and arthrodesis. Each has its proponents. Although no ideal treatment of ankle arthritis exists, high-quality studies can help guide treatment in patients of varying demographics. Inherent risks are linked with each treatment option, but those of greatest concern are early implant loosening that requires revision following arthroplasty and the acceleration of adjacent joint degeneration associated with arthrodesis.

Abstract
BACKGROUND The objective of this study was to identify factors influencing operative outcomes in straightforward, uncomplicated open ankle fusions. METHODS We reviewed all primary open ankle fusions conducted at 1 institution over an 11-year period to identify straightforward, uncomplicated open ankle fusions. Inclusion required a minimum of 6 months follow-up. Patients were excluded for neuropathic arthropathy, insensate limb, failed total ankle replacement, simultaneous arthrodesis of the subtalar joint, or fusions performed within 1 year of injury to salvage failed fixation and painful function due to (1) open fractures, (2) segmental bone loss greater than 1 cm, (3) infection, or (4) talar body fractures. The primary outcome variable was radiographic union at 6 months. Other operative complications were analyzed as secondary outcomes. Five hundred twenty-eight ankle fusion surgeries were performed on 440 patients at 1 institution during the study period. Two hundred fifteen surgeries met inclusion/exclusion eligibility criteria for uncomplicated open ankle fusions. RESULTS The overall union rate was 91%. In this cohort of uncomplicated open ankle fusions, bivariate analysis over a broad range of potential factors and further focused multivariate analysis found that nonunion was more than 3 times more likely to occur after previous subtalar fusion, and 2 times more likely to occur in patients with preoperative varus ankle alignment. The rate of reoperation was 19%, with nonunion revision as the leading reason, followed by hardware removal and incision and drainage for presumed infection. Diabetes was not a significant risk factor of either deep or superficial infection. CONCLUSION Open ankle fusion failed in 9% of uncomplicated ankles with arthritis. Patients who had an open ankle fusion done after previous subtalar joint fusion, as well as those who had preoperative varus ankle alignment, had a significantly higher rate of nonunion. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Complex ankle arthrodesis is defined as an ankle fusion that is at high risk of delayed and nonunion secondary to patient comorbidities and/or local ankle/hindfoot factors. Risk factors that contribute to defining this group of patients can be divided into systemic factors and local factors pertaining to co-existing ankle or hindfoot pathology. Orthopaedic surgeons should be aware of these risk factors and their association with patients' outcomes after complex ankle fusions. Both external and internal fixations have demonstrated positive outcomes with regards to achieving stable fixation and minimizing infection. Recent innovations in the application of biophysical agents and devices have shown promising results as adjuncts for healing. Both osteoconductive and osteoinductive agents have been effectively utilized as biological adjuncts for bone healing with low complication rates. Devices such as pulsed electromagnetic field bone stimulators, internal direct current stimulators and low-intensity pulsed ultrasound bone stimulators have been associated with faster bone healing and improved outcomes scores when compared with controls. The aim of this review article is to present a comprehensive approach to the management of complex ankle fusions, including the use of biophysical adjuncts for healing and a proposed algorithm for their treatment.

Abstract
Ankle arthrodesis is a common procedure that resolves many conditions of the foot and ankle; however, complications following this procedure are often reported and vary depending on the fixation technique. Various techniques have been described in the attempt to achieve ankle arthrodesis and there is much debate as to the efficiency of each one. This study aims to evaluate the efficiency of anterior plating in ankle arthrodesis using customised and Synthes TomoFix plates. We present the outcomes of 28 ankle arthrodeses between 2005 and 2012, specifically examining rate of union, patient-reported outcomes scores, and complications. All 28 patients achieved radiographic union at an average of 36 wk; the majority of patients (92.86%) at or before 16 wk, the exceptions being two patients with Charcot joints who were noted to have bony union at a three year review. Patient-reported outcomes scores significantly increased (P < 0.05). Complications included two delayed unions as previously mentioned, infection, and extended postoperative pain. With multiple points for fixation and coaxial screw entry points, the contoured customised plate offers added compression and provides a rigid fixation for arthrodesis stabilization.

Abstract
BACKGROUND Avascular necrosis (AVN) or persistent nonunion occurs in situations of poor vascular supply. Some specific situations that plague the foot and ankle surgeon are talus nonunion, talus AVN, navicular AVN, and failed ankle arthrodesis with bone loss. The medial femoral condyle (MFC) flap has emerged as a popular source of vascularized corticocancelous bone. We present a series of cases demonstrating the versatility of the MFC flap in complex foot and ankle pathology. METHODS A retrospective review was completed of all MFC flaps used in the foot and ankle over the past 5 years. Five patients were identified (average age 48). Surgical indications included talar AVN and ankle arthritis, talar nonunion, and navicular AVN. All patients had undergone conventional bone grafting techniques, which failed, prior to being treated with a MFC free flap; this series of patients did not possess significant medical comorbidities. Fixation techniques included compression screw fixation, plate osteosynthesis, or fine wire external fixation. The average follow-up was 20 months (range 8 to 40 months). RESULTS There was a 100% flap success rate with no returns to the operating room for thrombosis. The volume of the bone flaps was 5.6 cm(3) (range 1 cm(3) to 12 cm(3)). The average follow-up time was 20 months (range 8 to 40 months). All cases resulted in union, and full weight bearing status was achieved at a mean of 23.8 weeks (range 10 to 52 weeks) postoperatively. CONCLUSIONS Vascularized bone transfer in the form of the MFC free flap was a valuable method for foot and ankle reconstruction. The MFC flap provided an alternative for those defects that were smaller then 3 cm in length. In our experience, for small bone defects requiring vascularized bone, the MFC flap is currently the ideal donor location supplanting the iliac crest.

Abstract
BACKGROUND An increasingly popular ankle fusion method uses plates and screws positioned on the anterior aspect of the tibiotalar joint. This study compared the mechanical properties of 2 contemporary plate systems for ankle arthrodesis, one based on a single anterior plate and the other comprising paired anteromedial and anterolateral plates. METHODS Ten matched pairs of fresh-frozen cadaver ankle joints underwent arthrodesis with a single anatomically contoured anterior plate or 2 anatomic plates applied anteromedially and anterolaterally. Each arthrodesed specimen was subjected to controlled sagittal and coronal plane bending and internal and external rotation. Tibiotalar joint bending stiffness, bending angulation, torsional stiffness, and joint rotation were documented. RESULTS Bending stiffness of the 2-plate system was 1.5 to 5 times greater than that of the single-plate system in plantarflexion, dorsiflexion, eversion, and inversion (P = .005-.050). Angulation in each bending direction was several-fold greater than for the single plate (P = .005-.014) at the peak applied moment. Torsional stiffness of the 2-plate system nearly doubled that of the single plate in both rotation directions (P = .014, P = .005). Approximately half as much arthrodesis site rotation occurred with 2-plate fixation at the peak applied torque (P = .005, P = .007). CONCLUSION The tested 2-plate arthrodesis system has the potential to optimize arthrodesis site stiffness compared with fixation with a contemporary single plate. CLINICAL RELEVANCE Use of the stiffer 2-plate system could improve the clinical fusion rate, especially in patients with suboptimal bone quality.

Abstract
BACKGROUND Tibiotalocalcaneal (TTC) arthrodesis using a nail has been shown to be an effective salvage technique; however, there is a risk of major amputation. A better understanding of the relative risk of amputation after TTC fusion and the factors that influence this could help the preoperative consultation and guide discussion on the economics of limb salvage. METHODS One hundred seventy-nine limbs were treated with TTC fusion with an intramedullary nail. A comprehensive chart and radiographic review was pulled from our intramedullary nail database. Patients were divided into those who went on to eventual amputation and those with successful salvage of their limb. Variables from the database were used to build a statistical model with a biostatistician. Final results were presented, and a formula to determine probability of amputation was created. RESULTS There were 21 limbs that were eventually treated with major amputation. This represents an overall salvage rate of 88.2% (158/179 patients). Age was a factor in amputation risk, and the highest risk factor for amputation was diabetes with an odds ratio of 7.01 and 95% confidence, P = .0019. The odds of amputation were 6.2 times and 3 times greater for patients undergoing revisions and those with preoperative ulcers, respectively. The probability of amputation could be found preoperatively by using the derived equation: e(x) /(1 + e(x) ) where x is a factor of age, diabetes, revision, and ulceration. CONCLUSION TTC arthrodesis with a retrograde intramedullary nail has a high rate of limb salvage across a wide range of indications and medical comorbidities. In this patient cohort, diabetes was the most notable risk for amputation, followed by revision surgery, preoperative ulceration, and age. A model has been built to help predict the risk of amputation. LEVEL OF EVIDENCE Level II, prognostic.

Abstract
BACKGROUND Ankle arthrodesis may be achieved using the Ilizarov method. Comorbidities, such as diabetes, Charcot neuroarthropathy, osteomyelitis, leg length discrepancy, and smoking, can make an ankle fusion complex and may be associated with lower rates of healing. QUESTIONS/PURPOSES We asked if (1) smoking and other comorbidities led to lower fusion rates, (2) time wearing the frame affected outcome, and (3) simultaneous tibial lengthening improved fusion rates. METHODS We retrospectively studied 101 patients who underwent complex ankle fusion using the Ilizarov technique. The median time wearing the frame was 25 weeks (range, 10-65 weeks). Twenty-four patients had simultaneous tibial lengthening. The minimum followup for 91 of the 101 patients was 27 months (median, 65 months; range, 27-134 months). RESULTS Fusion was achieved in 76 of 91 patients. Smoking was associated with a 54% rate of nonunion. Fifteen of 19 patients with Charcot neuroarthropathy achieved union but had a high rate of subsequent subtalar joint failure. Time wearing the frame did not affect union rates. Tibial lengthening did not improve ankle fusion rates. CONCLUSION Smokers should be warned of the high risk of nonunion and we recommend they quit smoking. We also recommend surgeons recognize the higher nonunion rate in patients with Charcot neuroarthropathy. We believe tibial lengthening should not be performed to enhance healing at the fusion site.

Abstract
The use of bone morphogenetic protein-2 (BMP-2) has been recommended for high-risk fusions and nonunion. Patients undergoing revisional tibiotalocalcaneal (TTC) arthrodesis via a retrograde arthrodesis nail to evaluate the influence of BMP-2 on rate of fusion in this high-risk population are presented. A retrospective chart and radiographic review were performed on 23 patients with failed prior fusion attempts at the ankle treated with retrograde intramedullary nailing. Sixteen patients were treated without BMP-2 (None group) and 7 were treated with BMP-2 (BMP group). The primary and secondary end-points were successful fusion, and time to fusion, respectively, with a variety of variables evaluated for influence. Other than the use of BMP-2, there were no statistical differences in the patient population. Overall, 11 of 16 ankles (68.8%) in the None group and 5 of 7 ankles (71.4%) in the BMP group resulted in a stable, functional limb. Rate of complication was similar between the 2 groups (p > .05). Time to radiographic ankle union was 115.2 and 184.0 days in the None and BMP groups (p > .05). The effect of BMP-2 on revisional TTC fusions with retrograde nails is reported here. The overall result as a stable, functional limb was 69.6%, which suggests that revision surgery in this high-risk population is a reasonable consideration. Even though this study was unable to demonstrate statistically significant differences, biologic augmentation with BMP-2 did not increase the complication rate and showed a slightly enhanced salvage rate for revision TTC fusions with an intramedullary nail.

Abstract
BACKGROUND High rates of arthrodesis nonunion have been described in the ankle, hindfoot and midfoot in patients with significant risk factors. The purpose of this study was to evaluate fusion rates, risk of reoperation, postoperative pain scores and patient satisfaction for a slot graft inlay arthrodesis technique used in a high-risk group of foot and ankle patients. MATERIALS AND METHODS We retrospectively reviewed all ankle, hindfoot and midfoot arthrodeses by two foot and ankle surgeons in our institution between January 2000 and January 2009. Seventeen arthrodesis procedures in 16 patients using the slot graft technique were identified. Patient charts were reviewed for medical history, risk factors, previous surgery and postoperative complications. Time to union was evaluated on radiographs. Patients provided final followup by phone with an assessment of pain, overall satisfaction and use of orthotic or assistive devices. RESULTS Union occurred in 13 arthrodesis procedures (77%) with an average time to union of 5 months. Postoperative infection occurred in one patient. Additional surgery was performed in nine patients. At final followup patients reported low pain scores (3 of 10) and high satisfaction (8 of 10). Fourteen of 15 patients contacted indicated that they would choose to undergo the procedure again. CONCLUSION The slot graft arthrodesis technique provided satisfactory results in this small group of patients with a low complication rate. Patient satisfaction rates were high with low pain scores at an average of 62 months postoperatively.

Abstract
BACKGROUND The current study presents our experience with conversion of failed TAA to fusion. MATERIALS AND METHODS A retrospective review of all failed total ankles converted to fusion from 1999 to 2009 was performed at our institution. RESULTS Twelve total ankles were converted to isolated ankle fusions (Group I) and 12 converted to ankle-hindfoot fusions (Group II). All isolated ankle fusions were stabilized with anterior plate and screws with one nonunion. Structural bone graft was used in ten of 12. Mean outcome scores using the AOFAS-Ankle/Hindfoot score and Maryland Foot Score improved from preoperative values of 43 ± 13 and 56.7 ± 14 to 67 ± 12 and 71.2 ± 16 postoperatively, respectively (p < 0.05). All Group II ankle-hindfoot fusion patients were fixed using either anterior plate and screws, intramedullary nail, or a combination nail:plate construct. All received structural allografts. Five patients developed nonunion including four subtalar nonunions Preoperative scores on the AOFAS-AHS and MFS were 48.8 ± 14 and 58.3 ± 14. Postoperative scores were 51.2 ± 17 for the AOFAS and 64.5 ± 14 for the MFS. These changes were not statistically significant. However, the difference in nonunions was significant, p < 0.05. CONCLUSION Failed total ankles can be successfully converted to fusion using structural bone graft and internal fixation. The primary risk appears to be nonunion of the subtalar joint when ankle-hindfoot fusion is required. We believe this risk can be decreased by using a separate approach for preparation of the subtalar joint.

Abstract
Tibiotalocalcaneal arthrodesis is indicated for pain relief in patients with combined arthritis of the ankle and subtalar joint. An arthroscopic posterior approach was designed to improve upon traditional methods by using a minimally invasive technique. The technique involves prone positioning of the patient, one anterolateral and two posterolateral portals, and arthroscopic debridement of both the tibiotalar and posterior talocalcaneal joint. Stabilisation is obtained with a retrograde intramedullary nail, with static interlocking. This article presents illustrative cases and discusses some of the technical advantages and disadvantages over conventional open surgery. For surgeons familiar with posterior ankle or subtalar arthroscopy, this minimally invasive debridement and nailing appears to offer superior exposure, high patient satisfaction and lower postoperative morbidity than traditional methods; fusion is encouraged by preserving the medullary reaming material at the site of the fusion.

Abstract
BACKGROUND Arthrodesis is the most common procedure used to treat end-stage osteoarthritis of the ankle, particularly in patients with difficult conditions such as poor bone quality. While many techniques are available to fuse the ankle, current recommendations favor the use of internal fixation with screws and/or plates. Despite of progress, the complication rate remains a major concern. Non-union is one difficult problem especially with difficult bone conditions, particularly the loss of bone stock on the talar side. Therefore, fusion of the tibiotalar joint is often extended to the talocalcaneal joint to provide sufficient stability. To preserve the subtalar joint, an anterior double plate system for rigid fixation of isolated tibiotalar arthrodesis was developed. This is a preliminary report on the clinical and radiological outcome with this technique. MATERIALS AND METHODS Twenty-nine patients (15 men, 14 women; one ankle per patient) were treated from October 2006 to September 2007. We converted 16 ankles with osteoarthritis and difficult bone conditions, four non-united ankle arthrodeses, and nine failed total ankle replacements to an isolated tibiotalar arthrodesis using anterior double plating. If necessary, we used solid allograft to fill bony defects. Outcomes included bone union as assessed by radiographs, pain as indicated by the American Orthopaedic Foot and Ankle Society scores, and patient satisfaction. RESULTS Solid arthrodesis was achieved after an average of 12.3 (eight to 26) weeks in the 16 ankles without bone graft interposed between the tibia and talus, and 14.3 (range, 8 to 26) weeks in the 13 ankles with interpositional bone allograft. Radiographs showed that the position of arthrodesis obtained at the time of surgery did not change in any patient up to one year after surgery. The mean American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot Score increased from 37 (range, 20 to 63) preoperatively to 68 (range, 50 to 92) at the last followup. Twenty-seven patients (93%) were satisfied with their outcome and indicated they would have the operation again. No complications were noted. CONCLUSION The anterior double plating system was shown be a reliable method to achieve solid isolated tibiotalar arthrodesis, even in ankles with difficult conditions such as loss of bone stock due to failed total ankle arthroplasty.
