Abstract
Osteochondral lesions of the talus are a common sequelae of trauma and are often associated with ankle sprains and ankle fractures. Because the surface of the talus is composed primarily of hyaline cartilage, the regenerative capacity of these injuries is limited. Therefore, several open and arthroscopic techniques have been described to treat osteochondral injuries of the talus and underlying bone marrow lesions. Throughout this review, these treatment options are discussed along with their indications and currently reported outcomes. A commentary on the authors' preferences among these techniques is also provided.

Abstract
BACKGROUND Osteonecrosis is a complication of talar neck fractures associated with chronic pain and poor functional outcomes. The Hawkins sign, the radiographic presence of subchondral lucency seen in the talar dome 6 to 8 weeks after trauma, is a strong predictor of preserved talar vascularity. This study sought to assess the accuracy of the Hawkins sign in a contemporary cohort and assess factors associated with inaccuracy. METHODS A retrospective review of talar neck fractures at a level-I trauma center from 2008 to 2016 was conducted. Both the Hawkins sign and osteonecrosis were evaluated on radiographs. The Hawkins sign was determined on the basis of radiographs taken approximately 6 to 8 weeks after injury, whereas osteonecrosis was determined based on radiographs taken throughout follow-up. The Hawkins sign accuracy was assessed using proportions with 95% confidence intervals (CIs), and associations were examined with Fisher exact testing. RESULTS In total, 105 talar neck fractures were identified. The Hawkins sign was observed in 21 tali, 3 (14% [95% CI, 3% to 36%]) of which later developed osteonecrosis. In the remaining 84 tali without a Hawkins sign, 32 (38% [95% CI, 28% to 49%]) developed osteonecrosis. Of the 3 tali that developed osteonecrosis following observation of the Hawkins sign, all were in patients who smoked. CONCLUSIONS A positive Hawkins sign may not be a reliable predictor of preserved talar vascularity in all patients. We identified 3 patients with a positive Hawkins sign who developed osteonecrosis, all of whom were smokers. Factors impairing the restoration of microvascular blood supply to the talus may lead to osteonecrosis despite the presence of preserved macrovascular blood flow and an observed Hawkins sign. Further research is needed to understand the factors limiting Hawkins sign accuracy. LEVEL OF EVIDENCE Prognostic Level III .

Abstract
The majority of patients with an osteochondral lesion of the talus (OLT) report a history of trauma. Therefore, it is important to assess for concomitant ankle instability when dealing with patients with a symptomatic OLT. The History; Alignment; Ligaments; Others "(HALO)" approach can be a helpful tool in the evaluation of patients with an OLT. If conservative treatment fails, surgery may be indicated. Although there is a lack of comparative studies investigating the effect of stabilization procedures on cartilage repair, we believe that addressing instability is a key factor in improving patient outcome.

Abstract
OBJECTIVES The objective of this work was to develop a model of intra-articular fracture (IAF) in a rabbit and document the speed and severity of degenerative joint changes after fracture fixation. METHODS With Institutional Animal Care & Use Committee approval, impact-induced IAFs were created in the distal tibia of 16 New Zealand White rabbits. Fractures were fixed with a plate and screws. Pain and function were monitored at regular postoperative intervals with limb loading analysis. Twelve or 26 weeks after fracture, animals were euthanized for histological assessment of cartilage degeneration and micro-computed tomography analysis of bone histomorphometry. RESULTS Eleven animals successfully completed the study. Maximum foot force in the fractured limb was 41% ± 21% lower than preoperative values ( P = 0.006) 12 weeks after fracture and remained 25% ± 13% lower ( P = 0.081) after 26 weeks. Cortical bone mineral density in micro-computed tomography images was 34% ± 13% lower 12 weeks after fracture ( P < 0.001) and remained (42% ± 8%) lower 26 weeks after fracture ( P < 0.001). Twelve weeks after fracture, Mankin scores of cartilage degeneration were significantly higher in the medial talus ( P = 0.007), lateral talus ( P < 0.001), medial tibia ( P = 0.017), and lateral tibia ( P = 0.002) of the fractured limb compared with the uninjured contralateral limb. Average Mankin scores in the talus increased from 12 to 26 weeks (5.9 ± 0.9 to 9.4 ± 0.4; P < 0.001 lateral; 5.4 ± 1.8 to 7.8 ± 2.0; P = 0.043 medial), indicating substantial and progressive joint degeneration. CONCLUSIONS The ankle joint of the New Zealand White rabbit provides the smallest available model of impact-induced IAF that can be treated with clinically relevant techniques and replicates key features of healing and degeneration found in human patients.

Abstract
BACKGROUND Prosthetic substitution of the talus presents a significant challenge to the foot and ankle surgeon. The shear and compressive forces on the talus and its tenuous blood supply lead to high rates of avascular necrosis and eventual talar collapse. The purpose of this systematic review is to evaluate whether total ankle total talus replacement (TATTR) leads to improved clinical and radiographic outcomes with appropriate safety metrics in patients with a history of avascular necrosis or significant trauma. METHODS We searched the concepts of talus, prosthesis, and arthroplasty in MEDLINE (PubMed), Embase (Elsevier), CINAHL Complete (EBSCOhost), and Scopus (Elsevier) from the database's inception through March 9, 2023. Inclusion Criteria were 1) previous trauma to the talus, 2) post-traumatic arthritis to the tibiotalar joint, 3) avascular necrosis of talus, 4) multiple failed prior interventions, 5) degenerative osteoarthritis to the tibiotalar joint, and 6) inflammatory arthropathy to tibiotalar joint. Patients less than 18 years of age and manuscripts in non-English languages were excluded. RESULTS Of the 7625 references, 16 studies met the inclusion criteria, yielding data from 136 patients (139 ankles). The studies varied in design, with case reports and retrospective case series being predominant. The overall weighted average modified Coleman Methodology Score (mCMS) was 70.4 out of 100, indicating moderate flaws in study design that may be subject to various forms of bias and possible confounders. Demographics showed a diverse range of etiologies, with alumina ceramic being the primary prosthesis material. Functional scores demonstrated improvements in dorsiflexion and plantarflexion, although patient-reported outcome measures (PROs) were inconsistently reported. Complications included fractures, heterotopic ossification, prolonged wound healing, and infections. Revision details were sparsely reported. CONCLUSION TATTR is a promising treatment modality for improving short-term functional outcomes for patients with avascular necrosis or trauma-related issues. However, this systematic review underscores the need for standardized reporting, longer-term follow-ups, and further research to establish the procedure's efficacy and safety, particularly in comparison to other treatment modalities.

Abstract
Lateral subtalar dislocations are rare and severe injuries caused by high-energy trauma, and they require urgent treatment. We reported two cases of lateral subtalar dislocation, which were treated with different methods. In case of open lateral subtalar dislocation, we used the method of distractional external fixation; the final outcome was good, without avascular necrosis of the talus. The case of closed subtalar dislocation has been treated with open reduction and K-wires fixation. The final outcome was poor, with avascular necrosis of the talus. Our opinion is that ligamentotaxis of the ankle and subtalar joint with unilateral external fixation unloads the talus and reduces the possibility of the development of avascular necrosis of the talus.

Abstract
Total talus arthroplasty (TTA) is a motion sparing procedure which can be utilized in specific and unique cases of talar necrosis and/or collapse. Literature on TTA is limited and predominantly composed of case studies or case reports. The purpose of this publication is to compile a systematic review of functional outcomes and complications associated with TTA. A search of current literature on TTA with >1-year follow-up was performed. Studies that described talar body implants or talonavicular implants were excluded. Twenty articles met inclusion criteria, which represented 161 TTAs. The average follow-up was 37.35 months (9-60 months). The indication for a TTA was predominately avascular necrosis of the talus, comprising 75.78% (122/161) of cases. The overall complication rate was 9.32% (15/161), with wound healing complications (5/161), replacement or implantation of a tibial component (4/161), and medial malleolus fracture (3/161) being the most common. One patient required proximal amputation due to residual pain and deformity. Functionally, American Orthopedic Foot and Ankle Score increased from 27.93 preoperative to 81.99 postoperative and Japanese Society for Surgery of the Foot Score increased from 43.2 preoperative to 89.34 postoperative. Visual analog scale pain score decreased from 6.44 to 2.60. Total ankle range of motion increased from 36.60° to 46.74°. Ankle plantarflexion increased by 3.45° and ankle dorsiflexion increased by 6.69°. Overall, available literature on TTA appears to be in favor of the procedure when indicated.Levels of Evidence: 4.

Abstract
We report a case of open talar fracture-dislocation (Gustilo-Anderson type IIIA) associated with a posterior tibial artery injury. The limb was aligned and splinted in the emergency department. In the operating theater, the posterior tibial artery was ligated, the talar neck fracture was reduced, and it was fixed with two Kirschner wires (K-wires). After K-wire removal, the patient underwent rehabilitation to regain function and resumed activities of daily living (ADL). At nine months of follow-up, the patient has a good ankle range of motion (ROM) and a congruent ankle joint but has developed avascular necrosis (AVN) of the talus. This case report highlights the high risk of talus AVN after open talar fracture dislocation. Preservation of the extruded talus and anatomical reduction can maintain ankle alignment, which is essential for arthrodesis in cases of AVN complications.

Abstract
INTRODUCTION Avascular necrosis (AVN) of the talus is 1 of the most difficult foot and ankle pathologies to diagnose and manage. The purpose of this study was to report on the functional outcomes of 3D-printed total talus replacement (TTR) in 2 patients with talar AVN who both underwent a failed revascularization. METHODS This is a case series of 2 patients with TTR after a failed revascularization and a comparison group of 25 patients with primary TTR. Clinical and functional outcomes are used to compare both groups. RESULTS Patient 1 had a postrevascularization Visual Analogue Scale (VAS) pain score of 9. Imaging showed failure of the medial femoral condyle to incorporate with talar fragmentation. Patient underwent TTR at 5 months postoperatively. At 2 years postoperatively, the patient underwent a cavovarus foot reconstruction; however, patient continued to suffer from ankle pain (VAS 6) and ultimately underwent below knee amputation at 3 years after the TTR. Patient 2 initially underwent a core decompression for a talar bone infarct followed by revascularization procedure at 6 months postoperatively due to persistent pain and bony infarcts. At 18 months postrevascularization, the patient had a VAS pain score of 9 and progression of the AVN. She underwent a TTR. At 1-year follow-up, the VAS pain score was 8. Both patients had an ankle plantarflexion of 30° at their last TTR follow-up. The comparison group consisted of 25 patients who underwent 3D-printed TTR with mean postoperative VAS score and ankle plantarflexion of 3.7° and 41.8°. CONCLUSION Patients 1 and 2 demonstrated reduced plantarflexion and ankle motion after TTR relative to the comparison group which improved in both physical assessments. The first patient needed a below knee amputation for persistent pain. Patient 2 showed less improvement in all the foot and ankle outcome scores as compared with the primary TTR group.

Abstract
BACKGROUND Treatment of bone lesions involved with the articular cartilage at the talus is challenging. We report the management of talus lesions, particularly tumors and avascular necrosis (AVN), at the articular surface through treatment with cement augmentation and autologous bone graft. METHODS Eight benign bone tumors and three cases of AVN were reviewed retrospectively at a mean follow-up of 56 months (range, 12-162). The mean age of all patients was 36.1 years old (range, 15-73) when assessed between February 2005 and November 2021. Curettage of tumorous and necrotic lesions resulted in significant bone defects filled with bone cement augmentation. Cartilage defects of the talar dome were supported with autologous cancellous bone graft. Tolerable weight-bearing ambulation was permitted immediately after surgery. Radiological and functional evaluations were recorded. RESULTS We observed an increase in the average The American Orthopaedic Foot and Ankle Score (AOFAS) (p = .003) and a decrease in the average Visual Analogue Scale pain score (p = .003). There was no statistically significant decrease in ROM before or after surgery (p = .114). Additionally, no talus collapse of the ankle joint occurred. Talar dome status did not aggravate before or after surgery, except for one patient. Despite no radiographic osteoarthritis exacerbation before or after surgery in six patients, five patients had osteoarthritic change. CONCLUSION Cement implantation and autologous bone graft performed simultaneously for benign bone tumors with joint cartilage damage and AVN are technically simple, have good outcomes, and may be a suitable alternative to standard treatments.

Abstract
CASE Avascular necrosis (AVN) of the talus in a 45-year-old female following subchondroplasty with calcium phosphate bone filler for treatment of anterolateral and posteromedial talar dome bone marrow lesions (BMLs). The patient subsequently presented as consultation, 18 months postoperatively, with AVN of the talus. After failing conservative management, the patient underwent a total ankle arthroplasty at 46 months after subchondroplasty with resolution of pain. CONCLUSION There are few studies that have reported on the safety of subchondroplasty of the talus. Given the tenuous blood supply to the talar body and poor patient outcomes associated with AVN, caution should be taken before extrapolating the generally positive results of subchondroplasty in the knee.

Abstract
The hindfoot consists of the talus and calcaneus, spans the tibiotalar to transverse tarsal joints, and is critical for support of body weight and absorption and transfer of physiologic loads during bipedal movements. Hindfoot fractures account for approximately 17% of foot and ankle fractures, with calcaneal fractures being more common than talar fractures. Hindfoot fractures are usually caused by high-impact axial loads such as falls from heights and motor vehicle accidents, and understandably, they are often seen in patients with polytrauma. Long term, these fractures have implications in development of posttraumatic osteoarthrosis with associated pain and stiffness, affecting daily living activities. An overview of the talus and calcaneus is presented, with emphasis on fractures with articular involvement-namely, the tibiotalar and subtalar joints. Articular talar and calcaneal injuries can also alter hindfoot alignment, causing ankle and foot function abnormalities. Optimal treatment-that is, restoration of articular surfaces and hindfoot alignment followed by rigid fixation until fracture union-is dependent on an accurate understanding of the injury that is well depicted with imaging, radiography and CT in particular. The discussion of talar and calcaneal fractures includes a review of the normal anatomy, epidemiologic factors, classification systems, and imaging and pathologic-anatomic features of common injury patterns. This review is intended to aid surgical management and restoration of articular and hindfoot alignment for optimal ankle and foot function, thereby reducing patient morbidity in these often devastating injuries. ©RSNA, 2022.

Abstract
Abstract
Background
Total talar replacement is normally stable and satisfactory. We studied a rational scaffold talus model for each size range created through topology optimization (TO) and comparatively evaluated a topologically optimized scaffold bone talus model using a finite element analysis (FEA). We hypothesized that the rational scaffold would be more effective for application to the actual model than the topologically optimized scaffold.
Methods
Size specification for the rational model was performed via TO and inner scaffold simplification. The load condition for worst-case selection reflected the peak point according to the ground reaction force tendency, and the load directions “plantar 10°” (P10), “dorsi 5°” (D5), and “dorsi 10°” (D10) were applied to select worst-case scenarios among the P10, D5, and D10 positions (total nine ranges) of respective size specifications. FEA was performed on each representative specification-standard model, reflecting a load of 5340 N. Among the small bone models selected as the worst-case, an arbitrary size was selected, and the validity of the standard model was evaluated. The standard model was applied to the rational structure during validity evaluation, and the TO model reflecting the internal structure derived by the TO of the arbitrary model was implemented.
Result
In worst-case selection, the highest peak von Mises stress (PVMS) was calculated from the minimum D5 model (532.11 MPa). Thereafter, FEA revealed peak von Mises stress levels of 218.01 MPa and 565.35 MPa in the rational and topologically optimized models, respectively, confirming that the rational model yielded lower peak von Mises stress. The weight of the minimum model was reduced from 1106 g to 965.4 g after weight reduction through rational scaffold application.
Conclusion
The rational inner-scaffold-design method is safer than topologically optimized scaffold design, and three types of rational scaffold, according to each size range, confirmed that all sizes of the talus within the anatomical dimension could be covered, which was a valid result in the total talar replacement design. Accordingly, we conclude that an implant design meeting the clinical design requirements, including patient customization, weight reduction, and mechanical stability, should be possible by applying a rational inner scaffold without performing TO design. The scaffold model weight was lower than that of the solid model, and the safety was also verified through FEA.

Abstract
An 18-year-old man presented with complaints of pain and swelling around the left ankle region. Local examination revealed diffuse, hard, mildly tender swelling with ill-defined margins over the medial aspect of the left ankle joint just below the medial malleolus. Radiographic and computed tomographic assessment revealed osteolytic lesion with moderately defined margins. Provisional diagnosis of Campanacci grade 2 giant cell tumor was made, which was later confirmed on histopathology. Extended intralesional curettage and reconstruction with polymethylmethacrylate cement was done under spinal anesthesia. Full weight bearing was allowed at 4 weeks when the below knee back slab was removed. Radiographic assessment was done every 3 months during the first year of follow-up and then every 6 months. No evidence of recurrence of tumor, collapse of talus, or avascular necrosis was found during follow-up. Managing such rare form of bone tumors with extended intralesional curettage and bone cement is an appropriate treatment and gives good functional results.Level of Evidence: Level V.

Abstract
Avascular osteonecrosis (AVN) of the talus (AVNT) is a painful and challenging clinical diagnosis. AVNT has multiple known risk factors and etiologies and presents at different stages in severity. Given these unique factors, the optimal treatment solution has yet to be determined. Both joint-preserving and joint-sacrificing procedures are available, including core decompression and arthrodeses. Recently, new salvage and replacement techniques have been described including vascularized pedicle bone grafts and total talus replacement using patient-specific prosthesis; however, evidence remains limited. This review examines the current trends AVNT treatment and the emerging data behind these novel techniques.

Abstract
Bone loss after avascular necrosis of the talus secondary to acute traumatic or chronic pathologies often requires surgical reconstruction. This study reports the early results of a sliding oblique hindfoot osteotomy for salvage procedures combined with tibiotalar arthrodesis to achieve a well-aligned, painless, plantigrade foot. All patients presenting to our institution with severe talus body defects requiring corrective surgery between January 2016 and August 2020 were included. An oblique osteotomy of the diseased talus was performed to correct anterior talus subluxation and prevent excessive loss of height at the tibiotalar apposition and to correct varus-valgus deformity. A retrograde hindfoot nail was used for intramedullary tibiotalocalcaneal arthrodesis. Patients were prospectively followed. Primary outcomes included assessment of mobility and union at 6 months. Secondary outcomes included 30-day postoperative complications, patient satisfaction and change in American Orthopaedic Foot & Ankle Society (AOFAS) score at 1-year postoperation. Nine patients underwent this procedure with a mean follow-up of 18 months (4-36 months). Average age was 66 (58-81) years. Mean body mass index was 33.7 (22-38) kg/m2. All patients went on to fusion and were ambulating at 6 months (n = 8). At 1 year, the mean improvement in AOFAS was 28.9 points (p < .05) (n = 7) and all patients were satisfied with the outcome of their treatment. This technique represents an alternative to conventional hindfoot salvage techniques showing predictable outcomes in complex hindfoot deformity with talar body collapse and anterior subluxation. Further quantitative studies are needed to define if this technique minimizes limb shortening/limb-length discrepancies when compared to traditional horizontal cuts.

Abstract
BACKGROUND Avascular necrosis (AVN) of the talus most commonly occurs secondary to trauma. Significant bone loss and collapse in severe talar AVN remains an operative challenge. Tibiotalocalcaneal arthrodesis (TTC) using femoral head allograft is at risk of collapse and subsidence. The use of a void-filling titanium truss can mitigate against this. This study describes the use of a novel keystone shaped 3D-printed titanium truss for treatment of severe talar AVN. METHODS Three patients with end-stage AVN of the talus were included. Each patient underwent a TTC arthrodesis with a custom-made, 3D-printed, keystone-shaped, truss implant in conjunction with a hindfoot intramedullary nail. Modified patient American Orthopaedic Foot & Ankle Society (AOFAS) scores were recorded at the preoperative, 6-month, 12-month, and annual postoperative timepoints. RESULTS All patients progressed to satisfactory radiological union by one year. Mean follow up time was 32 months (24-48 months). Mean preoperative modified AOFAS score was 5. There was progressive improvement in AOFAS scores from 6 months postoperatively. Mean modified AOFAS score improved from 28 at 6 months to 37 at 2 years postoperatively. CONCLUSION Custom-made 3D-printed titanium trusses provide promising outcomes for treating severe AVN of the talus. The "keystone" design is advantageous as it allows for bone stock preservation and conforms to the shape of the native calcaneum. All patients showed progressive improvements in outcomes at sequential time intervals postoperatively. The implant provides a strong mechanical structure resisting collapse and subsidence during the arthrodesis process. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
A trimalleolar ankle fracture is considered unstable and treatment is generally performed operatively. Computed tomography is important for the operative planning by providing an elaborated view of the posterior malleolus. Trimalleolar ankle fractures have a rising incidence in the last decade with up to 40 per 100,000 people per year. With a growing number of elderly patients, trimalleolar ankle injuries will become more relevant in the form of fragility fractures, posing a particular challenge for trauma surgeons. In patients with osteoporotic trimalleolar ankle fractures and relevant concomitant conditions, further evidence is awaited to specify indications for open reduction and internal fixation or primary transfixation of the ankle joint. In younger, more demanding patients, arthroscopic-assisted surgery might improve the outcome, but future research is required to identify patients who will benefit from assisted surgical care. This review considers current scientific findings regarding all three malleoli to understand the complexity of trimalleolar ankle injuries and provide the reader with an overview of treatment strategies and research, as well as future perspectives.

Abstract
There are few surgical options available to manage complex talar pathology that result in predictably acceptable functional and patient satisfaction scores. Recently, total talar replacement has gained popularity as a viable option. This study presents the clinical outcomes of a case series of total talar replacements in South Africa. A review of data for 8 (N = 8) consecutive patients who underwent total talus replacement between July 2014 and August 2018 was performed. The American Orthopedic Foot and Ankle Society hindfoot score was used to assess clinical function and the Short Form-36 was used to assess patient satisfaction. Patient demographics as well as data on pathology, range of motion, gait analysis, and radiological outcomes were included. The mean age was 46 (range, 23-71) years. Pathologies included trauma, avascular necrosis, and tumors. The mean duration of follow-up was 23 (range, 12-49) months. The mean American Orthopedic Foot and Ankle Society score was 79.25 (range, 69-88) and the mean Short Form-36 satisfaction score was 83.25 (range, 60-93). No revision surgeries have been performed to date. Seven patients demonstrated a mildly abnormal gait and 1 revealed a moderately abnormal gait. The patient with the longest duration of follow-up showed radiological changes of tibial wear, although he remained symptom free. Our experience with the patients described in this report leads us to believe that total talar replacement is a viable surgical option in appropriately selected patients with end-stage talar pathology in the short to medium term, without compromising future salvage options.

Abstract
BACKGROUND Valgus hindfoot is a very common postural deviation, and the associated foot pronation can be a triggering factor for diseases such as tarsal tunnel syndrome. RESEARCH QUESTION This work compares two techniques for hindfoot valgus correction: GPR (Global Postural Reeducation) and PIMT (Postural Integration by Manual Therapy). METHODS Sixty young adult subjects from the Brazilian Army with unilateral hindfoot valgus were selected and divided into two groups of 30 subjects, one treated with GPR and the other treated with PIMT. Differences between normal and valgus hindfeet (plantar surface and body weight load) for each subject were measured and analysed, using a baropodometer with subjects in static standing position for 5s. Measurements were performed before and after each treatment session (4 weeks, once a week), and 4 weeks after the end of treatment. RESULTS Data shows that both treatments were equally effective for improving symmetry in body weight load between feet and plantar surface. After 4 weeks from the end of treatment, both treatments were equally effective for body weight load symmetry, but plantar surface symmetry was better in PIMT treated subjects. SIGNIFICANCE This study shows that PIMT technique can be validated as a physical therapy procedure, at least for valgus hindfoot.

Abstract
Talar osteonecrosis results from trauma to the fragile blood supply to the talus. Many etiologies exist that can cause talar osteonecrosis, with the most common being talar neck fractures. Patients with talar osteonecrosis frequently present with progressive ankle pain and limited range of motion. Treatment strategy depends primarily on the stage of disease. Conservative care in the form of medications and bracing treatment can be beneficial for patients with low functional status and early disease stages. Surgical options also exist for early disease without talar collapse that can potentially preserve the tibiotalar joint. Once talar collapse develops, surgical treatment is move invasive and typically involves an arthrodesis or talus arthroplasty. Although some treatment guidelines exist based on the disease stage, talar osteonecrosis is a complex problem, and treatment strategy should always be determined on a case-by-case basis carefully examining all clinical aspects.

Abstract
BACKGROUND Talus avascular necrosis (AVN) is a challenging entity to treat. Management options depend on disease severity and functional goals. Total talus replacement (TTR) is a treatment option that maintains joint range of motion. The literature on TTR is limited with variability in implant design and material. The purpose of this study was to evaluate outcomes following TTR with a custom 3D printed metal implant. METHODS Patients who underwent TTR were retrospectively reviewed over a 3-year period. Basic demographic data and comorbidities were collected. Medical records were reviewed to obtain postoperative and preoperative visual analog scale (VAS) scores, Foot and Ankle Outcome Scores (FAOSs), ankle range of motion, and postoperative complications. Statistical analysis was conducted to compare clinical and patient-reported outcomes pre- and postoperatively. Twenty-seven patients underwent TTR for talar AVN with a mean follow-up of 22.2 months. RESULTS Ankle range of motion remained unchanged postoperatively. VAS pain scores improved postoperatively from 7.1 to 3.9 (P < .001). FAOSs improved postoperatively with regard to pain (P < .001), symptoms (P = .001), quality of life (P < .001), and activities of daily living (P < .001). There were 3 complications requiring reoperation in this cohort. CONCLUSION 3D printed TTRs represent a unique surgical option for patients with severe talar AVN. Patients in this cohort demonstrated significant improvements in pain scores and patient-reported outcomes. TTR allows for symptomatic improvement with the preservation of motion in individuals with talar collapse and AVN. LEVEL OF EVIDENCE Level IV, retrospective case series.

Abstract
BACKGROUND Fractures of the talus often lead to permanent restrictions of the affected limb. Possible alterations after these fractures in gait have not been evaluated yet. OBJECTIVE To evaluate possible alterations of gait by pedybarography after talar fractures. METHODS We conducted a retrospective single-centre study at a level I trauma center. Twenty patients with operatively treated talar fractures were followed up. Objective and subjective function of the ankle was measured using range of motion, clinical scores and dynamic pedobarography (emed-M; Novel, Germany). RESULTS There were 11 talar neck and 9 talar body fractures. All patients received screw fixation. There was a significant reduction in range of motion. The outcome was moderate to satisfying and the severity of the injury correlated with the clinical outcome and the range of motion. The presence of posttraumatic arthritis and joint incongruity lead to a decreased function of ankle and subtalar joint and resulted in a worse clinical outcome. AVN rate was associated to initial displacement. Dynamic pedobarography showed no significant changes in gait pattern. CONCLUSIONS Fractures of the talus lead to dissatisfaction, pain and malfunction. However, a change in gait pattern could not be proved.

Abstract
PURPOSE Avascular necrosis (AVN) after fractures of the talus is a distinct and challenging clinical entity that is associated with poor outcomes. Although several articles are published on the management of posttraumatic AVN of the talus, very little is known about the management of infected AVN after talus fractures. Therefore, three cases of infected AVN were treated successfully by extensive debridement, external fixation and arthrodesis. METHODS Three cases of infected AVN of the talus were encountered after a mean of 3 months (range 2-6 months) after initial reconstructive surgery. Suspected infection was confirmed by positron emission tomography scan (PET-CT). Management involved extensive debridement, PMMA cement if necessary and final fusion using medial external fixator, accompanied by culture guided antibiotics. Functional outcome was assessed using the Foot Function Index (FFI) and the American Orthopaedic Foot and Ankle Society hindfoot score (AOFAS). Quality of life (QOL) was measured by the EuroQol-5D (EQ-5D). RESULTS After a mean follow up of 24 months (range 13-29), FFI index scores ranged from poor to good (23, 50, 56) with similar AOFAS scores indicating poor to fair functional outcome (38, 41, 71). The EQ-5D score was 0.78. Overall patient satisfaction was high with a mean VAS of 8.3 (range 8-9). CONCLUSION Infected talar AVN is a rare condition associated with severe long-term morbidity in term of joint function. The authors recommend extensive debridement and arthrodesis by means of external fixation, followed by post-operative culture-guided antibiotics for the treatment of infected avascular necrosis of traumatic talar fractures. Shared decision-making and expectation management are of crucial importance and may lead to high patient satisfaction despite low functional outcomes. LEVEL OF EVIDENCE IV, Retrospective case series.

Abstract
BACKGROUND Comminuted talar fractures are rare. Generally, this fracture occurs as a result of high-energy injuries. Therefore, this operation is challenging for the surgeon. We started to replace the whole talus with a total talar prosthesis in cases of aseptic talar necrosis in 2005. Based on these results, replacement with a ceramic artificial talus was performed as the initial treatment for comminuted talar fractures. METHODS From 2009 to 2016, a total of 6 feet of 6 patients with comminuted talar dome fractures or talar body defects were replaced with a ceramic artificial talus. The patients' mean age was 40.3 years (range, 19-59). Postoperative assessments were performed in accordance with the American Orthopaedic Foot & Ankle Society (AOFAS) ankle/hindfoot score system. Postoperative range of motion and sports activities were also evaluated. Follow-up ranged from 12 to 84 (mean, 46.8) months. RESULTS The postoperative AOFAS score was on average 78.8 (64-100). The postoperative range of motion was on average 10 degrees (5-20) for dorsiflexion and 31 degrees (15-50) for plantarflexion. Three patients had returned to sport activities. CONCLUSION Prosthetic total talar replacement was a useful procedure for patients with comminuted talar fractures, which had good congruency of the custom-made implant with the adjacent joints, resulting in stability, and maintained ankle function. Furthermore, this procedure could prevent the complications of long-term external fixation and non-weight-bearing walking seen after open reduction and arthrodesis.

Abstract
Posttraumatic avascular necrosis (AVN) is osteonecrosis from vascular disruption, commonly encountered after fractures of the femoral neck, proximal humerus, talar neck, and scaphoid. These locations have a tenuous vascular supply; the diagnosis, risk factors, natural history, and treatment are reviewed. Fracture nonunion only correlates with AVN in the scaphoid. In the femoral head, the risk is increased for displaced fractures, but the time to surgery and open versus closed treatment do not seem to influence the risk. Patients with collapse are frequently symptomatic, and total hip arthroplasty is the most reliable treatment. In the humeral head, certain fracture patterns correlate with avascularity at the time of injury, but most do not go on to develop AVN due to head revascularization. Additionally, newer surgical approaches and improved construct stability appear to lessen the risk of AVN. The likelihood of AVN of the talar body rises with increased severity of talar injury. The development of AVN corresponds with a worse prognosis and increases the likelihood of secondary procedures. In proximal pole scaphoid fractures, delays in diagnosis and treatment elevate the risk of AVN, which is often seen in cases of nonunion. The need for vascularized versus nonvascularized bone grafting when repairing scaphoid nonunions with AVN remains unclear.

Long-term radiographic and clinical-functional outcomes of isolated, displaced, closed talar neck and body fractures treated by ORIF: the timing of surgical management. BMC Musculoskelet Disord 2019; 20:363. [PMID: 31391024 PMCID: PMC6686493 DOI: 10.1186/s12891-019-2738-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Accepted: 07/24/2019] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND The main purpose of this retrospective case series study was to evaluate long-term radiographic and clinical outcomes of a consecutive series of patients diagnosed with isolated, displaced, closed talar neck or body fractures treated by open reduction and internal fixation (ORIF). Secondly, the aim was to verify the influence of the location of talar fractures on the outcomes, the prognostic value of the Hawkins sign, whether operative delays promote avascular necrosis (AVN) and if the fractures require emergent surgical management. METHODS From January 2007 to December 2012, at our institution, 31 patients underwent ORIF through the use of screws. On the basis of Inokuchi criteria, the injuries were divided between neck and body fractures, which were classified according to Hawkins and Sneppen, respectively. The patients included were divided into two groups in relation to fracture location and complexity. Radiographic assessment focused on reduction quality, bone healing, the Hawkins sign and post-traumatic arthritis (PTA) development. For the clinical evaluation, clinical-functional scores (AOFAS Ankle-Hindfoot Score; MFS; FFI-17; SF-36) and VAS were determined, and statistical analysis was performed. RESULTS 27 patients, 19 males and 8 females, mean age 38.3 years, were included with an average follow-up period of 83.2 months (range 49-119). There were 9 neck and 19 body fractures; their reduction was anatomical or nearly anatomical in 22 cases, and all reached radiographic consolidation after a mean period of 3.4 months (range 1.7-7). The Hawkins sign was observed in 9 cases, in which necrosis did not develop. With a 0-11 day surgical timing interval, more than 60% of the patients obtained good or fair results with different scores, while 18 (66.7%) were completely satisfied (VAS: 9-10). The early complications included malunions (21.4%) and wound problems (25%); the late complications involved AVN (25%) and PTA (78.6%). CONCLUSIONS Despite a high rate of long-term complications, satisfactory clinical results were achieved. Talar fracture location did not influence the outcomes, the Hawkins sign was confirmed as a positive prognostic factor, and operation timing did not influence AVN development. Hence, these injuries do not require emergent surgical management by ORIF.

Abstract
OBJECTIVE Anatomical reduction and fixation of complex talar fractures (Hawkins type III and IV, Marti type III and IV) using a medial approach. INDICATIONS Displaced talar fractures (Hawkins type III and IV, Marti type III and IV) with the need for a medial malleolar osteotomy or the simultaneous treatment of a medial malleolus fracture. CONTRAINDICATIONS High perioperative risk, severe soft tissue injuries in the medial approach area, infected soft tissues. SURGICAL TECHNIQUE Medial arch-shaped approach about 12 cm in length over the medial malleolus using a simultaneous medial malleolus fracture or via an additional medial malleolar osteotomy. Dissection and retraction of the terminal branches of the saphenous vein and the saphenous nerve. Protection of the blood supply in the area of the medial talus and in the sinus tarsi. Reduction of the talar joint surfaces and reconstruction of the anatomical axes according to the preoperative planning by means of native radiological and computed tomographic imaging. Osteosynthesis adapted to the fracture type using Kirschner wires, conventional screws, cannulated screws, double-threaded screws, resorbable pins, magnesium screws, small fragment plates. POSTOPERATIVE MANAGEMENT Lower leg splint or orthesis for 6 weeks, partial weight-bearing with 20 kg for 10-12 weeks. Early range of motion exercise of the ankle, subtalar and mid-tarsal joints. RESULTS In the past 5 years, 11 patients with either Hawkins type III and IV or Marti type III and IV fractures were treated operatively using the arch-shaped approach. No soft tissue problems were seen related to the arch-shaped approach. Of the 7 patients who could be followed up after an average of 2 years, the mean American Orthopedic Foot and Ankle Score was 73. Avascular necrosis occurred in 3 cases (43%). These were partial necroses of less than one third of the talar body with asymptomatic course at the time of examination. In 4 patients (57%) radiographic signs of osteoarthritis occurred within 2 years, whereby in two of those cases (29%) an arthrodesis of the upper ankle was performed.

Abstract
Talar fractures are uncommon lesions (0.1-0.9%) and have a high rate of complications. One of the situations in which a fracture of the talus can occur is in the context of polytrauma which may further compromise the functional prognosis. The aim of this study was to analyze the functional results in patients with talar fractures whether or not they occurred in the context of polytrauma. Observational study on a retrospective cohort of 24 patients operated in our centre (2008-2016). They were grouped according to whether they were polytraumatized (ISS>16) or not (ISS≤16). Review of sociodemographic, radiographic, functional variables (VAS pain scale and FADI -Foot and Ankle Disability Index-) and the onset of complications such as arthrosis, arthrodesis or avascular necrosis. Review of 25 talar fractures in 24 patients with a mean age of 38 years (19-75) and a mean follow-up of 4.2 years (0.5-9). According to the ISS, 44% of patients (11) were polytraumatized and 56% (14) were not. The average score according to the FADI scale was 62 points for the polytraumatized patients and 76.9 for the non-polytraumatized patients. The pain according to the VAS scale was 5.8 points in the group of polytraumatized patients and 4.3 in the non-polytraumatized patient group. Regarding complications, 64% of the polytraumatized patients and 43% of the non-traumatized patients had a complication. 36% of the polytraumatized patients had clinical and radiological signs of subtalar arthrosis compared to 35% of the non-traumatized patients, of whom 27% underwent arthrodesis compared to 28% of the non-traumatized patients. 27% of the polytraumatized patients were diagnosed with avascular necrosis as opposed to 0% of the non-polytraumatized patients.

Abstract
Combined fractures of the talus and adjacent bones are rare. We present a case with a fracture of the talus body concurrently with a tibial shaft fracture. Open reduction and internal fixation were applied in the treatment of talus fracture. The tibial shaft fracture was treated with closed reduction and intramedullary nails. At 1-year follow-up, no complication occurred and the patient returned to work before the injury.

Abstract
Background Avascular necrosis at sites other than femoral head (AVNOFH)/Non-Femoral AVN is a rare entity. No standard of treatment still exists for treating early stages of AVNOFH with most of the cases eventually progressing to a late arthritic stage needing surgical intervention. Bisphosphonates have been shown to prevent disease progression, bone collapse, and the requirement for surgery in avascular necrosis of femoral head. The present study is conducted to evaluate the response of bisphosphonates in the non-surgical management of the early stages of AVNOFH. Materials and methods Prospectively collected data of 20 patients diagnosed with an early stage of AVNOFH and treated with the combination of oral alendronate 70 mg weekly and intravenous zolendronic acid (ZA) for 1 year, between Jan 2009 to Dec 2015, was evaluated retrospectively. Clinical evaluation was done using the visual analogue scale (VAS), mean analgesic requirement, and range of motion. Radiographs and magnetic resonance imaging (MRI) were taken to classify the stage of AVN, monitor radiological collapse, and evaluate radiological progression and bone marrow edema changes. Results In our analysis of 18 patients (2 lost to follow-up), 5 patients had AVN of the humeral head, 4 patients of the talus, 3 of the lunate, and 2 each of the scaphoid, medial tibial plateau, and second metatarsal head. Pain relief with the drop in VAS score was seen at a mean duration of 4.3 weeks (range 3–13 weeks) after the start of therapy. A 50% reduction in mean analgesic requirement was achieved in the first 6 weeks (2-11 weeks). MRI showed complete resolution of BME in 13 patients at 6 months and in 17 patients (94.4%) at 1 year. Radiological collapse was seen in 6 out of 18 patients at a mean follow-up of 35.3 months (range 14–56 months). Only one out of 18 patients enrolled required surgery. Conclusion A combination of oral alendronate and intravenous zolendronic acid provides a pragmatic solution to this rare entity of AVNOFH, where no standard treatment exists.

Abstract
Displaced talar neck fractures no longer constitute a surgical emergency; timing of definitive surgery has no bearing on the risk of osteonecrosis. Amount of initial fracture displacement is best predictor of osteonecrosis. Grossly displaced fractures or fracture-dislocations should be provisionally reduced, with or without temporary external fixation. Periosteal stripping should be limited to only that necessary to obtain anatomic reduction. Dissection within the sinus tarsi or tarsal canal should be avoided. Rigid internal fixation with solid cortical screws countersunk within the talar head and placed below the "equator" of the talar head is imperative for optimum stability.

Abstract
Osteonecrosis arises throughout the foot and ankle in various forms and due to numerous causes, with a thousand US cases per year estimated for the ankle alone. Although research continues to elucidate specific mechanisms at work, the pathophysiology remains poorly understood. Nevertheless, the various osteonecrosis pathways converge on osteocyte death, and bony lesions follow a pattern of progression. Understanding the specific anatomy and biomechanics associated with common forms of foot and ankle osteonecrosis should help guide diagnosis and interventions, particularly at earlier stages of disease where etiology-specific approaches might become optimal.

Abstract
Severe talar avascular necrosis has many etiologies and can cause bone loss/hindfoot deformity. Tibiotalar calcaneal arthrodesis is a salvage procedure after severe talar avascular necrosis. Large bone voids can present significant challenges. Modest successes have been reported with structural block allograft tibiotalocalcaneal arthrodesis using either plate and screws, intramedullary nail fixation, or a combination. The advent of 3-dimensional printed titanium trusses has given surgeons another option for filling voids and providing structural support to prevent collapse. Although these options expand the armamentarium, treating surgeons must adhere to principles of arthrodesis: stable constructs, thorough joint surface preparation, and correction of deformity.

Abstract
Avascular necrosis (AVN) of the talus bone is a progressive and debilitating consequence of trauma or exposure to a variety of risk factors. The Ficat classification describes current understanding of the natural history of AVN, including preclinical, preradiographic, precollapse, postcollapse, and arthritic stages. The size and location of the avascular region likely determines risk of progression; however, symptoms do not correlate with stage. Patients may be minimally symptomatic despite diffuse involvement for long periods. Joint-sparing strategies have shown promise but do not universally prevent progression of the disease. When bone structure fails, joint-sacrificing strategies may be required.

Abstract
Advanced ankle arthritis, avascular osteonecrosis, and osteomyelitis of the ankle remain a surgical challenge in the foot and ankle arena with limited treatment options. Multiple medical comorbidities contribute to total loss of the talus. Collapse of the talar body as a complication of total ankle arthroplasty, talectomy in infection, and septic talus necrosis or severe bone defects caused by tumor resection may result in need for total talar replacement. Ankle arthrodesis and tibiocalcaneal fusion after talectomy can produce severe disability of the ankle and foot. Total ankle replacement is a viable option for treatment of end-stage ankle arthritis in appropriate patient populations.

Abstract
More than 60% of the talar surface area consists of articular cartilage, thereby limiting the possible locations for vascular infiltration and leaving the talus vulnerable to osteonecrosis. Treatment strategies for talar osteonecrosis can be grouped into four categories: nonsurgical, surgical-joint sparing, surgical-salvage, and joint-sacrificing treatments. Nonoperative and joint-sparing treatments include restricted weight-bearing, patellar tendon-bearing braces, bone-grafting, extracorporeal shock wave therapy, internal implantation of a bone stimulator, core decompression, and vascularized or non-vascularized autograft, whereas joint-sacrificing or salvage procedures include talar replacement (partial or total) and arthrodesis. In patients with a Ficat and Arlet grade-I through III osteonecrosis, evidence in favor of a specific treatment is poor, although tibiotalar or tibiotalocalcaneal arthrodesis may represent a suitable salvage operation.

Abstract
Fracture-dislocations of the talus are one of the most complex injuries involving the foot and ankle. These injuries are often accompanied by additional traumatic orthopedic injuries, avascular necrosis, and infection. When approaching limb reconstruction and salvage, the overall prognosis and functionality of the limb are key factors to consider. In the present report, we draw attention to the importance of a multidisciplinary team approach for formulating a treatment plan that incorporates the talar injury and associated injuries or pathologic features. We also reviewed the published data related to avascular necrosis of the talus, open talar fracture management, and treatment outcomes.

Abstract
Introduction: Osteonecrosis of the talus is a fairly rare condition. Many predisposing factors have been identified including previous trauma, use of corticosteroids, alcoholism, and smoking. As a gold standard, magnetic resonance imaging (MRI) is the most sensitive and specific diagnostic examination to detect osteonecrosis. While many treatment options for talar osteonecrosis exist, core decompression is suggested on young patients with good outcome results. More recently, intraosseous stem cell and platelet-rich plasma (PRP) injection has been added to the core decompression procedure. Case Report: We report a successful treatment of early talar osteonecrosis ARCO I (Association Research Circulation Osseous) by core decompression combined with stem cell and PRP injection. On 3-month and 15-month follow-up, MRI showed complete resolution of the osteonecrotic changes together with clinical improvement. Conclusion: This modified technique is a viable treatment option for early talar osteonecrosis. Nevertheless, future prospects should include a study comparing this combined technique with plain core decompression.

Abstract
Fractures of the talus are significant injuries with associated significant complications where the recovery zenith is less frequently good to excellent, and more commonly fair to satisfactory. These outcomes are a consequence of combinations of the inherent intrinsic and surrounding anatomy, technical and logistic difficulties in adequate fracture access, and the high-energy mechanisms typically associated with these injuries that further traumatize the surrounding tissues. This article reviews and provides current management recommendations for these devastating injuries.

Abstract
UNLABELLED Talar body osteonecrosis can be a devastating, painful condition that is difficult to manage surgically when conservative treatments have failed. With early disease, nonoperative treatments can prolong the need for operative correction in the young patient. Later stage disease with extensive involvement may require a tibiotalocalcaneal (TTC) arthrodesis to retain functionality of the limb. This situation frequently requires a structural bone graft. Using the technique described in this article, the void resulting from collapse of the talar body is filled with talar allograft, which offers a more anatomic and structurally rigid construct than previously described methods using an allograft femoral head. We have found this technique to be more resilient and successful than other methods. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
BACKGROUND Fractures of the talus are uncommon injuries that usually involve the talar neck, rather than the talar body. This report is of a rare case of combined left talar neck fracture and adjacent joint dislocation with an ipsilateral bimalleolar ankle fracture. CASE REPORT A 37-year-old man presented with an injury to his left foot following a motor vehicle accident. When he presented to the hospital emergency department, his left foot and ankle were swollen, the overlying skin was intact but badly contused, and there was no neurovascular deficit. Radiographs of the left ankle showed a fracture of the talar neck and bimalleolar fracture. An initial closed reduction under anesthesia failed. Therefore, open reduction and rigid stabilization of all fractures were achieved surgically, followed by the application of an external fixator spanning the ankle and the subtalar joints. The external fixator was removed at six weeks, range of motion (ROM) exercises were commenced, and a non-weight-bearing mobilization protocol was continued for 12 weeks. At four-year follow-up, radiographs confirmed solid union of all fractures, and although avascular necrosis (AVN) of the talus and secondary ankle arthritis developed, the functional outcome was satisfactory. CONCLUSIONS The immediate management of talar neck fracture with dislocation combined with a bimalleolar fracture is important to prevent soft tissue complications and to improve the functional ROM of the ankle. However, AVN and post-traumatic osteoarthritis at both the ankle and the subtalar joints are still common sequelae of talus fracture.

Optimizing Arthroscopy for Osteochondral Lesions of the Talus: The Effect of Ankle Positions and Distraction During Anterior and Posterior Arthroscopy in a Cadaveric Model. Arthroscopy 2017; 33:2238-2245. [PMID: 28807507 DOI: 10.1016/j.arthro.2017.06.027] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2016] [Revised: 05/25/2017] [Accepted: 06/19/2017] [Indexed: 02/02/2023]
Abstract
PURPOSE To quantify arthroscopic accessibility of the talar dome with predefined ankle positions through anterior and posterior approaches. METHODS Fourteen below-knee cadaver specimens underwent preoperative range of motion assessments. A 30° 2.7-mm arthroscopic camera was used to mark accessible areas at varying ankle positions. Accessible regions were quantified using a surface laser scanner and digital 3 × 3 grid. Statistical analyses were performed to detect differences in arthroscopic accessibility between different flexion angles and noninvasive distraction. RESULTS The mean arthroscopic accessibility of the talus was 58.5% and 49.8% for the anterior and posterior approaches, respectively (P < .001). During anterior arthroscopy, accessibility increased with up to 30° of plantarflexion (P < .001). There were no significant differences in accessibility between flexion groups for the posterior approach. There was significantly greater central zone accessibility for anterior arthroscopy (87.7%) when compared with posterior arthroscopy (74.3%; P = .002). Arthroscopic accessibility increased with increasing ankle distraction for both the anterior and posterior approaches (parameter estimates ± standard error): anterior = 6.5% ± 1.3%/mm of distraction, P < .001; and posterior = 7.0% ± 2.8%/mm, P = .026. Frequency analysis showed that the posterior third of the talus was completely inaccessible in 7 out of 14 of ankles during anterior arthroscopy. The anterior third of the talus during posterior arthroscopy was inaccessible in 11 out of 14 ankles during posterior arthroscopy. CONCLUSIONS Ankle plantarflexion up to 30° may be adequate for anterior arthroscopy for osteochondral lesions of the talus (OLTs). Noninvasive distraction also increases accessibility during both anterior and posterior arthroscopy. Anterior arthroscopy should be used for central third OLTs due to greater accessibility. CLINICAL RELEVANCE Ankle positioning is an important consideration for anterior arthroscopy. Surgical approach used should match with the location of the OLTs.

Abstract
BACKGROUND The presence of nonunion of a talar fracture with displacement, together with complete avascular necrosis, is a challenging entity to treat. METHODS Twelve patients, 8 men (66.7%) and 4 women (33.3%), with nonunited talar fractures and extensive avascular necrosis of the talus were included. The average age was 27.7 years (range, 19-38 years). After exclusion of infection, the patients underwent resection of necrotic bone, bulk autograft, and fusion using an intramedullary nail. The posterior approach was used in 11 patients and the anterior approach in 1 patient. The primary outcome was solid osseous union at the ankle and subtalar level and between the talar head anteriorly and the posterior construct, as evidenced by computed tomographic examination. Functional assessment was performed with the American Orthopaedic Foot & Ankle Society score and subjective patient satisfaction Results: After a mean follow-up duration of 23 months (range, 12-60 months), solid osseous union was achieved in 8 patients (66.7%). Stable fibrous union was seen in 1 patient (8.3%). Three patients (25%) required reoperation, and osseous fusion was finally achieved. American Orthopaedic Foot & Ankle Society score improved from a mean of 39.3 (range, 12-56) preoperatively to 76.6 (range, 62-86) at last follow-up. Subjective patient satisfaction was graded good or excellent in all cases. CONCLUSION Resection of necrotic talar body and bulk autograft with tibiotalocalcaneal fusion by an intramedullary nail through a posterior approach was a reasonable option for the management of type IV posttraumatic talar deformity.

Abstract
Background Fractures of the talar neck are relatively uncommon yet current interventions suffer from a high incidence of complications and poor functional outcomes. In the present study, we report a surgical treatment of Hawkins type III talar neck fracture through the approach of medial malleolar osteotomy and mini-plate for fixation and discuss the therapeutic effects after long-term follow-up. Methods From January 2010 to January 2015, 21 patients with 22 fractures were treated using this approach within days of sustaining the injury. Clinical and radiographic data were collected during regular post-operative follow-ups. Health-related quality of life factors were evaluated using visual analogue scale (VAS). Functional outcomes were determined according the Hawkins score and the Ankle-Hind foot Scale of the American Orthopedic Foot and Ankle Society (AOFAS). Present of complications such as arthritis, avascular necrosis (AVN), and malunion were evaluated using radiographs and magnetic resonance imaging (MRI). Anatomical parameters of injured and corresponding uninjured talus were measured and compared using digital three-dimensional (3D) computer model. Results The mean duration of surgery was 65.6 ± 9.7 min. The average blood loss volume of the patients was 29.1 ± 5.7 ml. All the patients except 1 were followed up 18 to 41 months (average 29.6 months). The average VAS score for these patients was 3.2 ± 1.1, and the mean Hawkins score was 11.4 ± 3.4 at the final follow-up visit. The average AOFAS score was 72.8 ± 17.3. Nine patients outcomes were rated as “excellent”, 4 as “good”, 4 as “fair,” and 4 as “poor”. No malunion, screw loosening, plate breakage, or other internal fixation failures were found at final follow-up. Long-term complications included: 1 case of malunion, 5 cases of complete AVN, 8 cases of partial AVN, 13 cases of talocrural arthritis, 14 cases of subtalar arthritis, and 3 cases of talonavicular arthritis. Secondary surgery was performed in 4 cases. The relevant average anatomical data of injured and uninjured talus show no significant difference. Conclusions This surgical treatment we used here resulted in decreased soft tissue trauma, adequate exposure of talar neck, satisfactory performance of daily life activities, and quality of life following surgery and restoration of anatomy of injured talus. However, long-term complications such as arthritis and AVN are still commonly seen.

Abstract
Fractures of the talus are uncommon injuries that can have devastating consequences. The blood supply to the talus is tenuous and injuries are associated with a higher incidence of avascular necrosis and malunion. Talar neck fractures are the most common fractures. This review looks at the different types of fractures of the talus, particularly focusing on talar neck fractures. The diagnosis and management are discussed as well as the complications.

Abstract
Avascular necrosis (AVN) of bone is defined as the cellular death of bone components due to the interruption of the blood supply; the bone structures then collapse, resulting in pain and loss of joint function. Magnetic resonance imaging (MRI) is the gold standard to diagnose AVN. We present an unusual case of AVN of talus in a patient of thalassemia major that was diagnosed on the Tc-99m MDP bone scan with equivocal findings on MRI. Key Message: The diagnosis of AVN is primarily done using radiological investigations. However, the bone scan plays a role in the diagnosis in atypical presentations and should be considered when MRI is equivocal.

Abstract
Levetiracetam is a relatively novel antiepileptic drug used for the treatment of partial and generalized seizures in adult and children. Several animal studies describe a possible drug adverse effect on skeletal growth and metabolism. We present a case report of a 10-year-old female child who underwent a prolonged 7-year treatment with levetiracetam for sporadic secondary convulsions secondary to enterovirus encephalitis at the age of 15 months. This patient developed an osteochondritis dissecans lesion (OCD) of the talar head well treated conservatively. Only a few cases have been described of this rare type of OCD. We hypothesize a possible association between levetiracetam therapy and OCD development, suggesting the importance of long-term control of bone growth in levetiracetam-treated pediatric populations.

Abstract
BACKGROUND Little is known about the rate of, and factors affecting, progression of talar osteonecrosis related to sickle cell disease. Adult patients with sickle cell disease who presented with hip osteonecrosis were evaluated for talar osteonecrosis with radiographs and magnetic resonance imaging (MRI). Forty-five of them (75 tali) were diagnosed with talar osteonecrosis, and this group was evaluated for factors influencing the progression of the disease. METHODS Forty-five patients with sickle cell disease and osteonecrosis of the talus were identified with radiographs and MRI between 1985 and 1995. Seven of these patients were homozygous for hemoglobin S (S/S genotype), 26 had hemoglobin S/hemoglobin C, and 12 had hemoglobin S/beta-thalassemia. The talar osteonecrosis was graded with radiographs and MRI. The patients were followed with clinical examination and radiographs every 6 months until talar collapse and every year after the collapse. RESULTS The osteonecrosis was unilateral in 15 patients and bilateral in 30 at the time of the initial examination. Forty-five ankles were asymptomatic and 30 were symptomatic at the initial evaluation. MRI performed at the time of the most recent follow-up, and compared with MRI performed at diagnosis, did not show partial or total regression of the osteonecrosis in any of the patients, even those with asymptomatic stage-I osteonecrosis. At the time of the most recent follow-up (mean, 20 years; range, 15 to 25 years), pain and collapse had developed in all except 12 ankles. The stage of the osteonecrosis at the initial visit, pain, the genotype of the sickle cell disease, and the extent and location of the lesion in the talus were risk factors for progression of the disease. CONCLUSIONS In the majority of the patients with sickle cell disease, osteonecrosis of the talus should be expected to show relevant clinical and radiographic evidence of progression over a long period.
