Abstract
BACKGROUND Tibiotalocalcaneal arthrodesis in patients with large segmental bony defects presents a substantial challenge to successful reconstruction. These defects typically occur following failed total ankle replacement, avascular necrosis of the talus, trauma, osteomyelitis, Charcot, or failed reconstructive surgery. This study examined the outcomes of tibiotalocalcaneal (TTC) arthrodesis using bulk femoral head allograft to fill this defect. METHODS Thirty-two patients underwent TTC arthrodesis with bulk femoral head allograft. Patients who demonstrated radiographic union were contacted for SF-12 clinical scoring and repeat radiographs. Patients with asymptomatic nonunions were also contacted for SF-12 scoring alone. Preoperative, intraoperative, and postoperative factors were analyzed to determine positive predictors for successful fusion. RESULTS Sixteen patients healed their fusion (50% fusion rate). Diabetes mellitus was found to be the only predictive factor of outcome; all 9 patients with diabetes developed a nonunion. In this series, 19% of the patients went on to require a below-knee amputation. CONCLUSIONS Although the radiographic fusion rate was low, when the 7 patients who had an asymptomatic nonunion were combined with the radiographic union group, the overall rate of functional limb salvage rose to 71%. TTC arthrodesis using femoral head allograft should be considered a salvage procedure that is technically difficult and carries a high risk for complications. Patients with diabetes mellitus are at an especially high risk for nonunion. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
If adequate conservative measures for the treatment of end-stage ankle osteoarthritis have failed, surgery may be taken into consideration. After exorbitant failure rates in the beginning of total ankle replacement, nowadays this kind of treatment has regained lot of interest and has become a viable alternative to ankle fusion. The correct indication and a precise explanation of the surgical procedure, outcomes and potential complications provide a solid base for future success.Currently, there is no doubt that total ankle replacement has become an important player in the treatment of symptomatic and debilitating end-stage ankle arthritis. With increasing number of patients who undergo total ankle replacement the experience with this kind of procedure increases too. As a consequence several surgeons have started to stretch indications favoring total ankle replacement. However, it must be mentioned here, despite progress in terms of improved anatomical and biomechanical understanding of the hindfoot and improved surgical techniques and instruments, total ankle replacement and ankle fusion remain challenging and difficult procedures. We provide a review article including an overview of the relevant techniques. This article should serve as rough guide for surgeons and help in decision-making regarding total ankle replacement and ankle fusion.

Abstract
INTRODUCTION Fragility fractures of the ankle are increasing in incidence. Such fractures typically occur from low-energy injuries but lead to disproportionately high levels of morbidity. Ankle fractures in this age group are managed conservatively in plaster or by open reduction and internal fixation. Both modalities have shown high rates of failure in terms of delayed union or mal-union together with perioperative complications such as implant failure and wound breakdown. The optimal treatment of these patients remains controversial. OBJECTIVES We aimed to review the functional outcome of patients with ankle fragility fractures primarily managed using a tibio-talar-calcaneal nail (TTC). METHODS We retrospectively reviewed 31 consecutive patients primarily managed with a TCC nail for osteoporotic fragility fractures about the ankle. Data were collected via case notes, radiographic reviews and by clinical reviews at the outpatient clinic or a telephone follow-up. Information regarding patient characteristics, indication for operation, Arbeitsgemeinschaft für Osteosynthesefragen (AO) fracture classification, operative and postoperative complications, time to radiographic union and current clinical state including Olerud and Molander scores were recorded (as a measure of ankle function). RESULTS Nine of 31 patients had died by the time of follow-up. Mean preoperative and postoperative Olerud and Molander scores were 56 and 45, respectively. There were no postoperative wound complications. Twenty-nine of 31 patients returned to the same level of mobility as pre-injury. There were three peri-prosthetic fractures managed successfully with nail removal and replacement or plaster cast. There were two nail failures, both in patients who mobilised using only a stick, which were managed by nail removal. Ten of 31 patients were not followed up radiographically due to either infirmity or death. Thirteen of 21 followed up radiographically had evidence of union and 8/21 had none. None, however, had clinical evidence of fracture nonunion. CONCLUSION The TTC nail can successfully be used to manage fragility fractures about the ankle in the elderly. Much like fractured neck of femur patients, who also have a high rate of mortality, this allows immediate mobilisation with minimal risk of wound complications. However, careful assessment must be made of each patient's mobility, as there is a significant incidence of device failure in the more active patient.

Abstract
Introduction In our experience, revision ankle arthroplasty with a three-component total ankle prosthesis following a failed total ankle replacement has provided encouraging midterm results with substantial pain relief while preserving the range of motion of the replaced ankle. Step 1 Preoperative Assessment and Planning Determine the treatment using a decision algorithm. Step 2 Patient Positioning Use spinal or general anesthesia, administer intravenous antibiotics, position the patient supine, and apply a tourniquet. Step 3 Surgical Approach to the Failed Prosthesis Use an anterior approach to expose the failed ankle prosthesis. Step 4 Removal of the Prosthesis Remove the polyethylene insert, the talar component, and the tibial component, making sure to not compromise any remaining bone stock. Step 5 Revision Ankle Arthroplasty Prepare the tibial and talar bone stock to obtain solid osseous surfaces, and use the appropriate prosthetic components. Step 6 Additional SurgicalProcedures If Necessary If necessary, perform arthrodesis of adjacent joints, correcting osteotomies of the distal parts of the tibia and fibula, calcaneal osteotomy, and/or ligamentoplasty. Step 7 Closure of All Incisions Close all incisions. Step 8 Postoperative Care A short leg splint is worn for two days, followed by partial weight-bearing; the ankle is protected in a splint at night and with a walking boot during the day for six to eight weeks. Results Between 2000 and 2010, 117 ankles in 116 patients (fifty-six female and sixty male; mean age, 55.0 ± 12.0 years) who presented with a failed total ankle arthroplasty after a mean of 4.3 ± 3.9 years were treated by revision arthroplasty with use of the HINTEGRA three-component total ankle prosthesis12.

Abstract
Total ankle replacement has become a popular treatment of symptomatic end-stage ankle osteoarthritis. Contemporary total ankle replacement systems provide more anatomic and biomechanically sound function. However, longevity is still limited and long-term results of modern total ankle replacement designs are not available. In the case of failure, conversion into arthrodesis has remained the treatment of choice but at the cost of hindfoot function and potential degeneration of the adjacent joints. Thus, revision total ankle replacement by exchange of the prosthetic components represents an attractive solution. This article focuses on revision total ankle replacement and conversion to ankle arthrodesis.

Abstract
Although mid- to long-term results after total ankle replacement have improved because of available second- and third-generation devices, failure of total ankle replacement is still more common compared with total hip replacement and total knee replacement. The portfolio of available total ankle replacement revision component options is small. Furthermore, the bone stock of the tibiotalar region is scarce making it difficult and in some situations impossible to perform revision total ankle replacement. In these cases tibiotalar and tibiotalocalcaneal fusions are valuable options. This article describes which surgical procedures should be performed depending on the initial situation and gives detailed advice on surgical technique, postoperative care, and clinical results.

Abstract
Total ankle replacement is now acknowledged as a viable alternative to ankle arthrodesis for end-stage ankle arthritis. The authors present a series of 14 patients who were converted from the Agility total ankle replacement to an INBONE total ankle replacement. This report is unique in that anterior and posterior approaches are discussed and detailed. Although the authors present successful conversion of the Agility total ankle replacement to an INBONE total ankle replacement, the difficulty of this procedure is demonstrated by the high complication rate and 2 early failures.

Abstract
Fusion remains the primary technique to salvage the failed total ankle. Fusions present a daunting challenge because of the large bone defect left by the explanted arthroplasty components and the difficulty obtaining stable fixation. Limiting the fusion to the tibiotalar joint preserves the essential motion of the hindfoot. However, because of loss of talar bone stock, it is often necessary to include the subtalar joint in a tibiotalocalcaneal fusion. This article discusses how to determine whether an isolated ankle or ankle-hindfoot fusion is indicated and presents surgical techniques for filling the bone defect and achieving stable internal fixation.

Abstract
BACKGROUND Failed total ankle arthroplasty (TAA) often results in significant bone loss and requires salvage arthrodesis. This study quantified the bone loss following failed TAA and reports the outcome of seven arthrodesis reconstructions using the Ilizarov method. METHODS A retrospective review of ankle fusions was performed for failed TAA to collect the mode of implant failure, presenting limb length discrepancy (LLD), total bone defect, postarthrodesis LLD, and treatment type (shoe lift versus distraction osteogenesis) and amount (shoe lift or lengthening). RESULTS Four mechanical failures and three infections were found. Four of seven cases had prior revision TAAs. Four of seven patients were treated with tibiotalar arthrodesis; three of the seven patients required talar resection and tibiocalcaneal arthrodesis. The mean presenting LLD was 2.2 (range, 1.2 to 3.5) cm. The mean time in frame was 197 (range, 146 to 229) days. With a mean postexplantation total bone defect of 5.1 (range, 3.7 to 8.5) cm, four of seven patients elected tibial lengthening following fusion [mean lengthening 4.6 (range, 2.5 to 8.0) cm; external fixation index (EFI) 42.6 (range, 16.5 to 55.6) days/cm)]. Three of seven patients were treated with a shoe lift [mean lift height 2.9 (range 2.5 to 3.2) cm]. There was no failure of fixation, refracture, or infection. All patients had a stable plantigrade foot and walked with minimal limp. Association for the Study and Application of the Method of Ilizarov (ASAMI) functional scores were six good and one fair. ASAMI bone scores were four excellent and three good. CONCLUSIONS Ankle arthrodesis following failed TAA results in large LLDs secondary to bone loss during implant failure and subsequent explantation. External fixation can produce an excellent fusion rate in complex, possibly infected, failed TAAs. Limb length equalization (by either distraction osteogenesis or shoe lift) provides a means of obtaining good functional outcomes following failed TAA.

Abstract
OBJECTIVES Tibiotalar (TT) arthrodesis is still a very important option in the treatment of primary or post-traumatic arthritis of the ankle but persists the controversy regarding the optimal method for the fixation of the arthrodesis site. No matter the implant used, the goal is to obtain a solid, healthy, pain-free fusion. The purpose of the current study is to present the preliminary results of a novel laterally based tibiotalar compression arthrodesis system using a locked plate. METHODS Thirteen consecutive patients with tibiotalar arthritis were submitted to an arthrodesis using a new lateral plating system. The average age was 59.7 years (range 36~72); nine patients were male and four female. Using a cutting guide, the remaining articular surfaces of the tibia and talus were removed. A compression device was applied to avoid malalignment of the ankle and a precontoured lateral locking plate was used to achieve the joint fusion. RESULTS Both the AOFAS ankle-hindfoot score and the VAS score improved with the surgery. All patients' ankles fused by 6 months. In all patients we found a very good alignment in the sagittal, coronal and transverse planes. CONCLUSION We believe that a combination of a bilateral compression, contoured bony cuts, and lateral locked plating offers a novel, accurate and useful technique for ankle arthrodesis.

Abstract
BACKGROUND The management of failed total ankle replacement (TAR) depends on the primary indication, presence of infection, condition of adjacent joints, and available bone stock. In addition, the patient's expectations, age, and general health should also be taken into account. METHODS This article describes a technique of arthrodesis in failed TAR with two parallel screws inserted in opposite directions and autologous cancellous bone graft. Four patients were managed using this technique. The subtalar joint and both malleoli were preserved. RESULTS The average time for radiological union was 14.8 weeks. There were no hardware-related complications or infections. One patient developed subsequent subtalar arthritis and is waiting for subtalar joint fusion. CONCLUSION The results from this small series of patients suggest that arthrodesis following failed total ankle replacement with two parallel screws and bone graft may be an effective technique.

Abstract
Large defects of the talus, i.e. due to tumors, large areas of osteolysis in total ankle replacement (TAR) and posttraumatic talus body necrosis are difficult to manage. The gold standard in these circumstances is still tibiocalcaneal arthrodesis with all the negative aspects of a completely rigid hindfoot. We started 10 years ago to replace the talus by a custom-made, all cobalt-chrome implant (laser sintering). The first patient with a giant cell tumor did very well but the following patients showed all subsidence of the metal talus into the tibia due to missing bony edges. Therefore, we constructed a custom-made talus (mirrored from the healthy side) and combined it with a well functioning total ankle prosthesis (Hintegra). So far we have implanted this custom-made implant into 3 patients: the first had a chondrosarcoma of the talus (1 year follow-up), the second had massive osteolysis/necrosis of unknown origin (6 months follow-up) and the third massive osteolysis following a correct TAR (2 months follow-up). The results are very encouraging as all of the patients are practically pain free and have a good range of movement (ROM): D-P flexion 15°-0-20° but less motion in the lower ankle joint: ROM P-S 5°-0-5°. No subsidence was detected in the tibia or the calcaneus. The custom-made talus combined with the Hintegra total ankle replacement will probably be an interesting alternative to a tibiocalcaneal arthrodesis in selected cases with massive defects of the talus.

Abstract
BACKGROUND Structural bone grafts are often used in foot and ankle surgery to fill gaps, maintain height, length or correction. Bone graft, whether autograft or allograft, has limitations and disadvantages. With porosity and mechanical properties similar to native bone, porous tantalum has been used successfully in hip and knee applications. This study investigates the potential advantages of porous tantalum as a substitute for conventional bone graft in foot and ankle surgery. METHODS A retrospective review of 27 arthrodesis procedures was performed of foot and ankle procedures using Trabecular Metal porous tantalum over a period of 5 years. Twenty-five patients were involved. Mean age at the time of surgery was 63 (range, 41 to 80) years. All the patients had pathologies in the foot and ankle that required arthrodesis with structural graft. Average followup was 27 (range, 12 to 72) months. RESULTS At final followup the mean American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot/Midfoot score improved from 40.6 (range, 16 to 64) preoperatively to 86.3 (range, 57 to 100) postoperatively (p < 0.001). When the pain component of the AOFAS was examined, the score improved from a mean of 8.2 (range, 0 to 20) to 35.2 (range, 20 to 40), (p < 0.001). At the time of last followup, 56% of patients reported no pain, 40% reported mild occasional pain, and 4% reported moderate pain. CONCLUSION Porous tantalum therefore, was found to be a viable alternative to conventional bone graft when structural support was required.

Abstract
There are limited options for failed total ankle arthroplasty (TAA) with major talar bone loss and component subsidence. Surgical options for this condition include revision arthroplasty, salvage arthrodesis, or amputation. Revision arthroplasty generally has been considered in situations of loose components with minimal bone loss or use of expensive custom-fabricated prosthetic components with elongated stems. Historically, failure that involves major talar bone loss has been considered resistant to reconstruction, and responsive only to complex arthrodesis or amputation. In this report, we describe a unique method of restoring talar support and preserving ankle function after failed TAA with major talar bone loss and component subsidence. Talar reconstruction using metal-reinforced bone cement augmentation is combined with the Inbone (Wright Medical Technology, Inc., Arlington, TN) total ankle system to restore talar height and ligamentous support. This technique has been used successfully in the last 4 years for various patterns of talar bone loss and obviates the need for custom components. When successfully performed, the revision technique results in restoration of mechanical alignment, anatomic height, and component support, in addition to providing substantial symptomatic relief.

Abstract
BACKGROUND The SALTO total ankle prosthesis is a noncemented mobile bearing anatomic design characterized by dual Ti-HA coating. This study reviews our results with this prosthesis. MATERIALS AND METHODS Between 2001 and 2007, 413 consecutive SALTO prostheses were implanted in our institution in 215 women and 198 men, aged 57.1 +/- 11.9 years. At the last visit, 401 implants (47% in the left ankle) were available with a mean followup of 29 (range, 1 to 84) months. RESULTS Based on the results of the 218 patients with at least 2 years of postoperative followup, the 5-year estimated survivorship, with the primary end-point being implant removal, was 86.6% and ranged from 85.1% in patients with post-traumatic osteoarthritis to 95.6% in those with rheumatoid arthritis. The AOFAS score increased from 50.9 +/- 16.8 points preoperatively to 82.2 +/- 14 points at followup (mean difference, 31.1 +/- 1.4, 95% confidence interval (C.I.) for the difference, 28.3 to 33.8, p < 0.001). Visual analog scale for pain decreased from 7.4 +/- 1.1 preoperatively to 2.0 +/- 2.0 postoperatively (mean difference, -5.4 +/- 0.7, 95% C.I. for the difference, -5.6 to -5.2, p < 0.001). Flexion/extension ROM increased from 25.2 +/- 14.1 degrees to 33.1 +/- 13.6 degrees at the last followup visit (mean difference, 7.9 +/- 0.5 degrees, 95% C.I. for the difference, 4.3 to 7.2, p < 0.001), while pronation/supination ROM increased from 23.8 +/- 13.7 degrees to 25.4 +/- 14.5 degrees (mean difference, 1.6 +/- 0.7 degrees, 95% C.I. for the difference, 0.9 to 2.2, p = 0.005). CONCLUSION The SALTO prosthesis provided good clinical and functional results and we believe helps validate the concept of anatomic replacement.

Abstract
INTRODUCTION. The role of total ankle replacement (TAR) is expanding in the United States. As the number of ankles implanted increases, undoubtedly the number of failures will increase. Several reports in the literature have dealt with salvage of the failed TAR through various methods. MeTHODS. A retrospective chart and radiographic review was performed on all patients who had conversion from a failed Agility TAR to an INBONE TAR at 2 centers and had been performed at least 12 months prior to the study. Exclusion criteria included any patient converted from a different type of TAR, primary TAR, patients followed less than 12 months, and surgical approach other than the standard anterior incision. RESULTS. Five patients met inclusion criteria. The average age was 65.6 ± 13.6 years (range = 45-79 years). Complicating comorbidities were found with 4 patients. The average follow-up was 17.2 ± 6.6 months (range = 7-25 months). The cause of failure of the original Agility TAR was coronal plane deformity in 3 patients, and 1 patient each failed from extensive heterotopic ossification or infection. All patients presented with pain. In 4 cases, there was component subsidence at the talus, tibia, or both. All patients had adjunctive procedures at the time of the revision, including malleolar screw placement in 4 patients and hindfoot arthrodesis in 2 patients. All patients had either 4 or 5 tibial stem components placed. During the follow-up period, 3 patients required additional surgery, including 2 patients classified as failures (1 transtibial amputation and 1 tibiotalocalcaneal arthrodesis). DISCUSSION. This salvage option is technically demanding. The authors caution against TAR revision by conversion in the place of previous infection and in ankle imbalance not amenable to reconstruction. In all cases the initial deformity was corrected. The early results, however, demonstrate high risk of early failure and positional changes.

Abstract
INTRODUCTION Arthrodesis is a well-established treatment option for end-stage osteoarthritis of the ankle. Osteoarthritis of the ankle can alter plantar pressure distribution. However, surprisingly little is known about the effect of ankle arthrodesis to alter plantar pressure distribution. The purpose of this study was to determine plantar pressure distribution in a selected group of patients with unilateral arthrodesis of the ankle joint. METHODS 20 patients with an average age of 60 years who underwent isolated unilateral ankle arthrodesis using a 3-crossed screw technique by a single surgeon were included. After a mean of 25 months (range 12-75 months) post surgery plantar pressure distribution was determined in five regions of the foot. The outcome was evaluated clinically, using the American Orthopaedic Foot and Ankle Society hindfoot score, as well as radiographically. The contralateral normal foot was used as a control. FINDINGS Comparing the foot that underwent tibiotalar arthrodesis to the contralateral normal foot, differences were found in the peak pressure and maximum force in the toe region and the lateral midfoot region. In addition, a decrease in the contact time in the forefoot region and a decrease of the contact area in the toe region of the operated foot were identified. The other regions did not show a significant difference. The mean American Orthopaedic Foot and Ankle Society score of the operated leg was 79 (range 46-92) at the last follow up, and the mean fixation angle of the arthrodesis on lateral weight bearing radiographs was 90° (range 86°-100°). INTERPRETATION Our results indicate that arthrodesis of the ankle joint can provide high levels of function with minimal changes in the plantar pressure distribution.

Abstract
The anatomic compression arthrodesis technique with anterior plate augmentation is an effective technique that results in a high union rate, improved functional outcome, and an acceptable complication rate. This technique can be used for both primary ankle arthrodesis and salvage cases with significant bone loss. The authors believe the anterior plate is a useful complement to standard multiplanar screw fixation, and the increased rigidity provided by the anterior plate effectively counters forces, particularly in the sagittal plane, that may otherwise lead to failure of multiplanar screw constructs.

Abstract
BACKGROUND Despite the appearance of new-generation, mobile-bearing, cementless prostheses, total ankle arthroplasty remains controversial. Among the criteria guiding the choice between arthrodesis and arthroplasty, the long-term survival and postoperative function are of critical importance. The mobile-bearing Salto prosthesis has been used in Europe since 1997, but only 2 to 5 years of followup data have been reported. QUESTIONS/PURPOSES We analyzed the longer-term survivorship and causes of failures of the Salto prosthesis in a cohort of previously studied patients. We asked whether this prosthesis provided a functional ankle (AOFAS score) and durable radiographic fixation. PATIENTS AND METHODS We retrospectively reviewed 96 prospectively followed patients with 98 prostheses implanted between 1997 and 2000. Of those, 85 patients (87 prostheses) had a minimum followup of 6.8 years (mean, 8.9 years; range, 6.8-11.1 years). RESULTS The survival rate was 65% (95% CI, 50-80) with any reoperation of the ankle and 85% (95% CI, 75-95) with revision of a component as the end points. Six prostheses were removed for arthrodesis, and 18 ankles underwent reoperation without arthrodesis. We observed three main causes of reoperations: bone cysts (11 patients), fracture of the polyethylene (five patients), and unexplained pain (three patients). The mean AOFAS score was 79 ± 12 points. Radiographic subsidence was observed in three patients and bone cysts in eight patients. CONCLUSIONS Our data suggest a high rate of reoperations but only six revisions with arthrodesis with mid-term followup. We observed few patients with loosening and/or subsidence.

Abstract
BACKGROUND AND PURPOSE Arthrodesis after failed total ankle replacement is complicated and delayed union, nonunion, and shortening of the leg often occur-especially with large bone defects. We investigated the use of a trabecular metal implant and a retrograde intramedullary nail to obtain fusion. PATIENTS AND METHODS 13 patients with a migrated or loose total ankle implant underwent arthrodesis with the use of a retrograde intramedullary nail through a trabecular metal Tibial Cone. The mean follow-up time was 1.4 (0.6-3.4) years. RESULTS At the last examination, 7 patients were pain-free, while 5 had some residual pain but were satisfied with the procedure. 1 patient was dissatisfied and experienced pain and swelling when walking. The implant-bone interfaces showed no radiographic zones or gaps in any patient, indicating union. INTERPRETATION The method is a new way of simplifying and overcoming some of the problems of performing arthrodesis after failed total ankle replacement.

Abstract
While ankle arthrodesis has remained the gold standard treatment for symptomatic primary, secondary, and posttraumatic ankle arthritis, more recently, total ankle replacement (TAR) has seen considerable improvement in terms of biomechanics, function, and complication rates. However, while in the long-term degeneration of the adjacent joints is almost always found on radiographs after ankle arthrodesis, the longevity of TAR is still insufficient and does not match that of total knee and hip joints. The current review article focuses on the treatment of ankle arthritis by means of arthrodesis and TAR.

Abstract
Critical-sized defects in bone, whether induced by primary tumor resection, trauma, or selective surgery have in many cases presented insurmountable challenges to the current gold standard treatment for bone repair. The primary purpose of a tissue-engineered scaffold is to use engineering principles to incite and promote the natural healing process of bone which does not occur in critical-sized defects. A synthetic bone scaffold must be biocompatible, biodegradable to allow native tissue integration, and mimic the multidimensional hierarchical structure of native bone. In addition to being physically and chemically biomimetic, an ideal scaffold is capable of eluting bioactive molecules (e.g., BMPs, TGF-betas, etc., to accelerate extracellular matrix production and tissue integration) or drugs (e.g., antibiotics, cisplatin, etc., to prevent undesired biological response such as sepsis or cancer recurrence) in a temporally and spatially controlled manner. Various biomaterials including ceramics, metals, polymers, and composites have been investigated for their potential as bone scaffold materials. However, due to their tunable physiochemical properties, biocompatibility, and controllable biodegradability, polymers have emerged as the principal material in bone tissue engineering. This article briefly reviews the physiological and anatomical characteristics of native bone, describes key technologies in mimicking the physical and chemical environment of bone using synthetic materials, and provides an overview of local drug delivery as it pertains to bone tissue engineering is included.

Abstract
UNLABELLED Ankle arthroplasty is increasingly used to treat advanced ankle arthritis. Earlier prostheses have given way to second-generation implants, on which we are accumulating medium-term data. The Scandinavian Total Ankle Replacement (STAR) is a three-component uncemented implant in wide use in Europe and the only mobile-bearing prosthesis with conditional approval in the United States. We retrospectively reviewed 45 patients (52 ankles) who had primary total ankle replacements using STAR prostheses, in order to assess survivorship and add to the pool of clinical data provided by independent practitioners required to establish this treatment as a viable alternative to arthrodesis. The minimum followup was 60 months (range, 60-110 months). Clinical outcome was determined using the AOFAS score. We determined the rate of radiographic loosening and recorded complications and the need for further surgery. Survival was 90% (95% CI 76.8 to 95.5) at 5 years and 84% (95% CI 68.9 to 92.2) at 8 years. Six of 52 ankles (11%) had component revision and two were converted to fusion. The mean postoperative AOFAS score was 78. The complication rate was 21%. Subsequent surgery, excluding component revision, was performed in nine of 52 (17%) ankles.

Abstract
BACKGROUND Ankle arthrodesis and replacement are two common surgical treatment options for end-stage ankle osteoarthritis. However, the relative value of these alternative procedures is not well defined. This study compared the clinical and radiographic outcomes as well as the early perioperative complications of the two procedures. METHODS Between January 2, 1998 and May 31, 2002, 138 patients were treated with ankle fusion or replacements. Seventy one patients had isolated posttraumatic or primary ankle arthritis. However, patients with inflammatory arthritis, neuropathic arthritis, concomitant hind foot fusion, revision procedures and two component system ankle replacement were excluded. Among them, one group of 42 patients had a total ankle replacement (TAR), whereas the other group of 29 patients underwent ankle fusion. A complete follow-up could be performed on 89% (37/42) and 73% (23/29) of the TAR and ankle fusion group, respectively. The mean follow-up period was 4.2 years (range, 2.2 to 5.9 years). RESULTS The outcomes of both groups were compared using a student's t-test. Only the short form heath survery mental component summary score and Ankle Osteoarthritis Scale pain scale showed significantly better outcomes in the TAR group (p < 0.05). In the radiographic evaluation, there was no significant difference in preoperative and postoperative osteoarthritis between the TAR and fusion groups. CONCLUSIONS The clinical results of TAR are similar to those of fusion at an average follow-up of 4 years. However, the arthroplasty group showed better pain relief and more postoperative complications that required surgery.

Abstract
BACKGROUND AND PURPOSE Total ankle arthroplasty (TAA) has gained popularity in recent years. If it fails, however, salvage arthrodesis must be reliable as a rescue procedure. We therefore investigated the clinical, radiographic, and subjective outcome after salvage arthrodesis in a consecutive group of patients, and concentrated on the influence of the method of fixation on union rate and on salvage in inflammatory joint disease. PATIENTS AND METHODS Between 1994 and 2005, salvage arthrodesis was performed on 18 ankles (18 patients). Diagnosis was inflammatory joint disease (IJD) in 15 cases and osteoarthritis (OA) in 3. Tibio-talar fusion was performed in 7 ankles, and tibio-talocalcaneal fusion in 11. Serial radiographs were studied for time to union. Clinical outcome at latest follow-up was measured by the AOFAS score, the foot function index (FFI) and by VAS scores for pain, function, and satisfaction. RESULTS Blade plates were used in 7 ankles (4 IJD, 3 OA); all united. Nonunion developed in 7 of the 11 rheumatic ankles stabilized by other methods. 11 patients (8 fused ankles, 3 nonunions) were available for clinical evaluation. Their mean AOFAS score was 62 and mean overall FFI was 70. VAS score for pain was 20, for function 64, and for satisfaction 74. The scores were similar in united and non-united ankles. INTERPRETATION Blade plate fixation is successful in salvage arthrodesis for failed TAA. A high nonunion rate was found after salvage ankle arthrodesis in IJD with other methods of fixation. Clinical results were fair to good.

Abstract
UNLABELLED A structural graft often is needed to fill gaps during reconstructive procedures of the ankle and hindfoot. Autograft, the current gold standard, is limited in availability and configuration and is associated with donor-site morbidity in as much as 48%, whereas the alternative allograft carries risks of disease transmission and collapse. Trabecular metal (tantalum), with a healing rate similar to that of autograft, high stability, and no donor-site morbidity, has been used in surgery of the hip, knee, and spine. However, its use has not been documented in foot and ankle surgery. We retrospectively reviewed nine patients with complex foot and ankle arthrodeses using a tantalum spacer. Minimum followup was 1.9 years (average, 2 years; range, 1.9-2.4 years). Bone ingrowth into the tantalum was analyzed with micro-CT in three of the nine patients. All arthrodeses were fused clinically and radiographically at the 1- and 2 year followups and no complications occurred. The American Orthopaedic Foot and Ankle Society score increased from 32 to 74. The micro-CT showed bony trabeculae growing onto the tantalum. Our data suggest tantalum may be used as a structural graft option for ankle and subtalar arthrodesis. All nine of our patients achieved fusion and had no complications. Using tantalum obviated the need for harvesting of the iliac spine. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
BACKGROUND The return to sporting activities after ankle arthroplasty has rarely been evaluated. The purpose of the present study was to evaluate function and return to sports after total ankle arthroplasty. MATERIALS AND METHODS One hundred seventy-nine Salto Total Ankle Arthroplasties (TAA) were implanted between 1997 and 2005. A self-administered questionnaire including the Foot Function Index (FFI) and Foot and Ankle Ability Measurement (FAAM) was sent to all patients. At last followup, six were deceased, 22 were not available for evaluation, and six questionnaires were incomplete. One hundred forty-five questionnaires were available. The mean age was 60.9 years and the mean followup was 53.8 months. The main indications for TAA were osteoarthritis (OA) in 100 cases and Rheumatoid arthritis (RA) in 40 cases. RESULTS 15.2% of the patients said that their operated ankle was "normal'' 60.7%" nearly normal''; 20% "abnormal'' and 4.1% "highly abnormal.'' The FFI scores were 13.7 +/- 17 for "activity limitations'', 31.7 +/- 23 for "disability'' and 16.9 +/- 19 for "pain''. The FAAM scores were 74.9 +/- 18 for activities of daily living and 48.9 +/- 28 for sports activities. On a Visual Analog Scales (0 to 100 were 100 is the "pre-pathology level'') the mean rating was 70.2 +/- 19.6 for Activities of Daily Living and 53.7 +/- 28 for sport activities. In the OA patients, 38 regularly road bicycle, 21 perform recreational gymnastics, 58 swimming, 50 home gardening, 27 dancing, and 43 hiking. Seven patients regularly practice tennis, nine cross-country skiing, 17 downhill skiing, and six regularly run more than 500 m. CONCLUSION This study showed that TAA improved the quality of life and that return to recreational activities was generally possible but the return to impact sport was rarely possible.

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.

Abstract
BACKGROUND The purpose of this study was to investigate the clinical and radiological results of calcaneal osteotomy, joint debridement and ligament reconstruction for the treatment of early to moderate stage osteoarthritis of the ankle. MATERIALS AND METHODS Eleven cases with osteoarthritis of the ankle, four with stage 2 and seven with stage 3, underwent joint debridement, cheilectomy, calcaneal osteotomy, deltoid ligament release, and lateral ligament reconstruction. The mean followup was 22.3 (range, 15 to 42) months. The American Orthopaedic Foot and Ankle Society(AOFAS) clinical ankle-hindfoot scale was used to evaluate clinical function of the ankle. Weightbearing anteroposterior and hindfoot alignment radiographs were evaluated for measuring of tibiotalar tilt angles, clear space ratio, heel alignment ratio preoperatively and at the last followup. RESULTS The mean AOFAS score improved from 42.8 points before surgery to 82.7 points at the last followup. The mean talar tilt angles improved from 7.4 degrees to 5.9 degrees. The mean medial clear space widened from 0.4 mm to 2.7 mm. The lateral clear space was narrowed from 6.8 mm to 4.8 mm. The medial to lateral clear space ratio of ankle was improved from 0.06 to 0.62. Heel alignment ratio was improved from 0.59 to 0.36. CONCLUSION Calcaneal osteotomy with ligament reconstruction can be considered for treatment of the early stages of osteoarthritis of the ankle.

Abstract
BACKGROUND Total ankle arthroplasty (TAA) is being carried out with increasing frequency and manufacturers are releasing new implant designs each year. METHODS We comment on the various designs and the outcome of the procedure as reported in the literature. No results have so far been published on the majority of the more recent designs and where outcome data are available, the follow up period is very short. RESULTS For those designs where 5 or 10 year follow-up studies have been performed, the survivorship at 5 years is over 90% in most instances and of the order of 80% at 10 years. The failure rate is lower in ankles that are well aligned at presentation than it is for those with more than 15 degrees varus or valgus deformity pre-operatively. CONCLUSIONS TAA has definite advantages over fusion for some patients and if selection criteria are adhered to, a long-lasting satisfactory outcome can be achieved.

Abstract
We carried out 123 consecutive total ankle replacements in 111 patients with a mean follow-up of four years (2 to 8). Patients with a hindfoot deformity of up to 10° (group A, 91 ankles) were compared with those with a deformity of 11° to 30° (group B, 32 ankles). There were 18 failures (14.6%), with no significant difference in survival between groups A and B. The clinical outcome as measured by the post-operative American Orthopaedic Foot and Ankle Surgeons score was significantly better in group B (p = 0.036). There was no difference between the groups regarding the post-operative range of movement and complications. Correction of the hindfoot deformity was achieved to within 5° of neutral in 27 ankles (84%) of group B patients. However, gross instability was the most common mode of failure in group B. This was not adequately corrected by reconstruction of the lateral ligament. Total ankle replacement can safely be performed in patients with a hindfoot deformity of up to 30°. The importance of adequate correction of alignment and instability is highlighted.

Abstract
The third annual Extremity War Injuries Symposium was held in January 2008 to review challenges related to definitive management of severe injuries sustained primarily as a result of blast injuries associated with military operations in the Global War on Terror. Specifically, the symposium focused on the management of soft-tissue defects, segmental bone defects, open tibial shaft fractures, and challenges associated with massive periarticular reconstructions. Advances in several components of soft-tissue injury management, such as improvement in the use of free-tissue transfer and enhanced approaches to tissue-engineering, may improve overall care for extremity injuries. Use of distraction osteogenesis for treatment of large bone defects has been simplified by the development of computer-aided distraction protocols. For closed tibial fractures, evidence and consensus support initial splinting for transport and aeromedical evacuation, followed by elective reamed, locked intramedullary nail fixation. Management of open tibial shaft fractures sustained as a result of high-energy combat injuries should include serial débridements every 48 hours until definitive wound closure and stabilization are recommended. A low threshold is recommended for early utilization of fasciotomies in the overall treatment of tibial shaft fractures associated with war injuries. For management of open tibial fractures secondary to blast or high-velocity gunshot injuries, good experiences have been reported with the use of ring fixation for definitive treatment. Treatment options in any given case of massive periarticular defects must consider the specific anatomic and physiologic challenges presented as well as the capabilities of the treating surgeon.

Abstract
Ankle arthrodesis is by no means a simple surgery. It requires preoperative planning, meticulous preparation of bony surfaces, cognizance of ankle positioning, and rigidity of fixation. The procedure also requires enough experience on the part of the operating surgeon to recognize important patient factors and to determine which type of ankle arthrodesis is most appropriate for that specific patient.

Abstract
INTRODUCTION Fragility fractures of the ankle are difficult to treat by conventional fixation due to poor bone quality, compromised soft tissues, and inherent instability. Conservative management of these patients also has its problems. MATERIALS AND METHODS We retrospectively reviewed 13 patients who underwent intramedullary nailing through the tibiotalocalcaneal joints in an attempt to achieve the dual aims of fracture control and early mobilisation. The Olerud and Molander scale was used as outcome measures. RESULTS There were 12 females and 1 male with a mean age of 78.9 (range 64-93). Half of the patients were discharged from hospital within the first 2 weeks after the operation. All achieved a comparable function to their pre-operative state. The mean follow-up period was 11 months (range of 2-62 months). Six are now deceased from unrelated causes. The mean Olerud and Molander score was 50 (range 30-65). All the radiographs showed evidence of fracture union with no changes in the overall alignment of the joint. CONCLUSION Given the low survivorship of this frail group of patients the main objectives are achieving early mobilisation whilst maintaining good fracture position. In our experience, tibiotalocalcaneal nailing is a very useful and successful way of treating fragility fractures of the ankle because it has a low risk of complications and restores function with impressive patient satisfaction. The potential benefits of this technique, we believe, outweigh the disability ensued from subtalar joint fusion.
