Abstract
BACKGROUND Posttraumatic osteonecrosis (ON) of the lateral distal tibia is a rare but severe complication of malleolar fractures. Treatment options include ankle fusion, arthroplasty, osteotomy, and drilling but clinical data on outcomes are limited to single case reports. The aim of this study was to prospectively evaluate the outcome following joint-preserving reconstruction. METHODS Over a 10-year period, 10 patients (8 females and 2 males, average age 36 years; range, 27-68 years) with posttraumatic ON were treated with intra-articular osteotomy of the distal tibia and bone grafting. All patients initially sustained a closed pronation injury, 7 with initial tibiotalar subluxation. Chronic syndesmotic instability following initial treatment was present in 4 patients and 5 were smokers. All patients were followed for a median of 68 (range, 12-103) months, 7 returned in person for clinical and radiographic follow-up. RESULTS No immediate postoperative complications were seen. Secondary ankle fusion was necessary in 1 case (10%) because of progressive osteoarthritis. At the time of follow-up, anterior ankle arthritis leading to impingement and requiring cheilectomy was noted in 4 cases, partial graft necrosis, and secondary syndesmotic instability requiring revision surgery was seen in 1 case each. Compared with the preoperative values, significant improvement in the Olerud-Molander Ankle Score (P = .012), EuroQuol-5 Score (P = .008), and Foot Function Index (FFI-D pain, P = .028; FFI-D restriction, P = .038) was seen. Average range of motion at the ankle was 45 degrees. CONCLUSION In our limited series of patients with posttraumatic ON of the lateral distal tibia, we found that joint-preserving reconstruction using an intra-articular distal tibial osteotomy with autologous bone grafting usually provided significant functional improvement and pain relief. In our cohort secondary fusions by a median 5.5-year follow-up were rare, but secondary, joint-sparing surgeries were common. LEVEL OF EVIDENCE Level III, prospective study.

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
Abstract
Background Navicular nonunion and talar avascular necrosis may result from limited blood supply predisposing to injury and impaired healing. Vascularized pedicled bone grafting is a promising adjunct to treat these challenging conditions, offering the susceptible diseased site structural and vascular support. We report the early radiographic and clinical outcomes of vascularized pedicled bone grafting in patients with navicular nonunion, talonavicular fusion nonunion, and talar avascular necrosis.
Methods Patients with navicular nonunion, talonavicular fusion nonunion, or talar avascular necrosis who underwent vascularized pedicled bone grafting at our institution from January 2014 to February 2019 were retrospectively identified. Radiographic evidence of healing was monitored postoperatively as defined by: progression toward union on CT for nonunion and absence of disease progression on MRI or CT for avascular necrosis. Surgical complications and need for additional surgeries were documented.
Results Eight patients were included who underwent vascularized pedicled bone grafting for navicular nonunion (N = 5), talonavicular fusion nonunion (N = 1), and talar avascular necrosis (N = 2). Average clinical follow-up was 10.8 months (range 4–37). All patients had 4 or more months postoperative radiographic follow-up with MRI or CT. Seven of eight patients demonstrated evidence of radiographic healing. One patient required additional surgery due to external fixator pin site infection. No other complications were reported.
Conclusion Our results corroborate prior case series suggesting vascularized pedicled bone grafting is a safe and reliable procedure for treating navicular nonunion, talonavicular fusion nonunion, or talar avascular necrosis with potential to spare or delay need for salvage procedures in the younger patient population.

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
PURPOSE Vascularized pedicled bone-grafting from the cuboid to the talus provides low donor site morbidity and satisfactory outcomes in patients with early-stage talar avascular necrosis. We investigated the anatomy of the rotational vascularized pedicled bone graft from the cuboid. METHODS 15 embalmed cadaver specimens were perfused with red latex via the popliteal artery. The lateral malleolus was dissected. The course of the lateral tarsal artery and the vascular territory in the cuboid supplied by the lateral tarsal artery were observed. Vessel diameters were measured. RESULTS The course of the lateral tarsal artery to the cuboid was consistent, and a vascularized pedicle of the lateral tarsal artery was present in all specimens. Mean diameter of the lateral tarsal artery was 1.40 ± 0.12 mm (range 1.67-1.25). Mean length of the vascularized pedicle was 67.15 ± 3.18 mm (range 62.43-74.36). The pedicle bone graft was long enough to reach the bony border of both the lateral and medial malleolus. CONCLUSION A vascularized pedicled cuboid bone graft based on the lateral tarsal artery has clinical utility for early-stage talar avascular necrosis.

Abstract
The 3D custom total talus replacement is a novel treatment for avascular necrosis of the talus. However, patients who require a total talus replacement often have concomitant degenerative changes to the tibiotalar, subtalar, or talonavicular joints. The combined 3D custom total ankle-total talus replacement (TATTR) is used for patients with an unreconstructable talus and adjacent tibial plafond involvement. The goal of performing a TATTR is to provide pain relief, retain motion at the tibiotalar joint, maintain or improve the patient's functional status, and minimize limb shortening. TATTR is made possible by 3D printing. The advent of 3D printing has allowed for the accurate recreation of the native talar anatomy with a talar dome that can be matched to a total ankle replacement polyethylene bearing. In this article, we will discuss a case of talar avascular necrosis treated with a combined TATTR and review the current literature for TATTR.

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
Talar osteochondral lesions (OCLs) lead to progressive stages of talar destruction. Core decompression with cancellous bone grafting (CBG) is a common treatment for Berndt and Harty stages II and III. However, in a subset of patients, talar revascularization may fail. Surgical angiogenesis using vascularized medial femoral condyle (MFC) autografts may improve on these outcomes. These 2 treatment strategies were directly compared via a prospective preliminary randomized trial including 20 participants with talar core decompression followed by either cancellous (CBG group, n = 10) or vascularized MFC (MFC group, n = 10) bone grafting. Outcome analysis was performed with visual analog scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, Lower Extremity Functional Scale (LEFS), and contrast-enhanced magnetic resonance imaging (MRI) scans. At 12 months of follow-up, the mean VAS score was reduced from 6.6 ± 2.5 preoperatively to 4 ± 1.9 in the CBG group and from 5.2 ± 2.9 preoperatively to 1 ± 1.1 in the MFC group (p < .001). The LEFS improved from 53.4 ± 13.1 to 62.6 ± 16.2 CBG and from 53 ± 9.3 to 72.4 ± 7.4 MFC (p = .114). AOFAS improved from 71 ± 12.1 to 84.1 ± 12.5 in CBG and from 70.5 ± 7.4 to 95.1 ± 4.8 in MFC (p = .019). The MRI scans in the CBG group demonstrated 9 partial malperfusions and 1 hypervascularized bone graft, whereas the MFC group had 8 well-vascularized grafts incorporated into the talus and 1 partial malperfusion. Vascularized MFC autografts provide superior pain relief along with improvement of physical function in patients with talar OCL stage II and III compared with CBG. To confirm these promising results, further multicenter randomized controlled trials are required.

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
The talus is unique in having a tenuous vascular supply and 57% of its surface covered by articular cartilage. Fractures of the head, neck, or body regions have the potential to compromise nearby joints and impair vascular inflow, necessitating surgical treatment with stable internal fixation in many cases. The widely preferred approach for many talar neck and body fractures is a dual anterior incision technique to achieve an anatomic reduction, with the addition of a medial malleolar osteotomy as needed to visualize the posterior talar body. Percutaneous screw fixation has also demonstrated success in certain patterns. Despite this modern technique, osteonecrosis and osteoarthritis remain common complications. A variety of new treatments for these complications have been proposed, including vascularized autograft, talar replacement, total ankle arthroplasty, and improved salvage techniques, permitting some patients to return to a higher level of function than was previously possible. Despite these advances, functional outcomes remain poor in a subset of severely injured patients, making further research imperative.

Abstract
BACKGROUND Patients with talar avascular necrosis (AVN) have limited treatment options to manage their symptoms. Historically, surgical options have been limited and can leave patients with little ankle motion and have high failure rates. The use of custom 3D printed total talar replacements (TTRs) has arisen as a treatment option for these patients, possibly allowing better preservation of hindfoot motion. We hypothesized that patients undergoing TTR will demonstrate a statistically significant improvement in Foot and Ankle Outcome Score (FAOS) at 1 year after surgery. METHODS We retrospectively reviewed 15 patients who underwent a TTR over a 2-year period. Patient outcomes were reviewed, including age, sex, comorbidities, etiology of talar pathology, number and type of prior surgeries, radiographic alignment, FAOS and Visual Analog Scale (VAS) score, and range of motion. Data analysis was performed with Student t-tests and multivariate regression. RESULTS FAOSs and VAS scores showed statistically significant improvements postoperatively as compared with preoperative scores. There was a statistically significant decrease in VAS pain scores from 7.0 preoperatively to 3.6 (P < .001). Average follow-up was 12.8 months. With the number of patients available, there was no statistically significant change in radiographic alignment parameters postoperatively as compared with preoperatively (P values ranged from .225 to .617). CONCLUSION Our hypothesis that these patients show statistically significant improvements in FAOSs at 1 year was confirmed. TTR represents an exciting treatment option for patients with talar AVN, though longer-term follow-up is needed.Level of Evidence: Level IV: Case series.

Abstract
We present the case of a 43-year-old boy who presented with progressive pain as a result of history of lateral avascular necrosis of the talus secondary to traumatic open ankle luxation 20 years ago. Conservative treatment (12-month period) prior to surgery failed. It consisted of physiokinetic treatment, insoles and analgesic medication. A diagnostic injection was used in the ankle (positive) and subtalar joint (negative) in order to recognize origin of pain. Hemilateral avascular necrosis of the talus is rare. There are no prior reported cases of the use of hemi-implants. This case highlights the potential use of a patient-specific three-dimensional printed Ti6Al4V prosthesis presented in a complex scenario.

Abstract
BACKGROUND In patients with avascular necrosis (AVN) of the talus in the precollapse stage unresponsive to conservative measures, joint preservation should be considered. Good results have previously been reported for vascularized bone grafting. The medial femoral condyle (MFC) free flap has recently been introduced, which consists of corticoperiosteal bone. We present a novel surgical technique using a periosteal-only MFC (pMFC) free flap in the treatment of talus AVN. METHODS We retrospectively reviewed all pMFC free flaps performed from 2016 to 2018 in the precollapse stage of talus AVN. Surgical management included an ankle arthroscopy, talus core decompression, and ipsilateral pMFC free flap to the talus. Foot and Ankle Ability Measure (FAAM)-Activities of Daily Living (ADL) and visual analog scale (VAS) pain scores were evaluated, and pre- and postoperative imaging studies were assessed by a musculoskeletal-trained radiologist for all patients. Six pMFC free flaps in 5 patients were included in this case series. AVN etiology included idiopathic, posttraumatic, and sepsis-related treatment. All patients were female with an average age of 44.2 (range, 37-67) years. Average postoperative follow-up was 16.9 (range, 6-28) months. RESULTS Pre- to postoperative FAAM-ADL, ADL single assessment numeric evaluation, and VAS scores showed statistically significant improvement (P < .039). No reoperations or flap complications were observed. There was 1 minor complication, which included postoperative paresthesias at the pMFC harvest site. Postoperative x-rays showed no subsequent collapse, and magnetic resonance imaging (MRI) illustrated progressive improvement of bone marrow edema, decreased surrounding areas of AVN, and decreased joint effusion when compared to preoperative MRI. CONCLUSION The pMFC free flap is a novel modification of a previously described technique, which appears to have similar results compared to the traditional MFC free flap. It was safe and effective in the short term with excellent clinical and radiographic outcomes. LEVEL OF EVIDENCE Level IV, case series.

Objective To investigate three-planar radiographic results and patient-reported outcomes (PROs) after correcting chronic atlantoaxial instability (AAI) by translaminar screw (TLS) and pedicle screw (PS) fixation, and to explore the potential association of atlantoaxial realignment with PRO improvements.
Methods Twenty-three patients who underwent C1 lateral mass screw (LMS)-C2 TLS and 29 who underwent C1 LMS-C2 PS with ≥ 2 years of follow-up were retrospectively analyzed. Three-planar (sagittal, coronal, and axial) radiographic parameters were measured. PROs including the Neck Disability Index (NDI), Japanese Orthopaedic Association (JOA) score and the Short Form 36 Physical Component Summary (SF-36 PCS) were documented. Factors potentially associated with PROs were identified.
Results The radiographic parameters significantly changed postoperatively except the C1–2 midlines’ intersection angle in the TLS group (p = 0.073) and posterior atlanto-dens interval in both groups (p = 0.283, p = 0.271, respectively). The difference in bilateral odontoid lateral mass interspaces at last follow-up was better corrected in the TLS group than in the PS group (p = 0.010). Postoperative PROs had significantly improved in both groups (all p < 0.05). Thereinto, NDI at last follow-up was significantly lower in the TLS group compared with PS group (p = 0.013). In addition, blood loss and operative time were obviously lesser in TLS group compared with PS group (p = 0.010, p = 0.004, respectively). Multivariable regression analysis revealed that a change in C1–2 Cobb angle was independently correlated to PROs improvement (NDI: β = -0.435, p = 0.003; JOA score: β = 0.111, p = 0.033; SF-36 PCS: β = 1.013, p = 0.024, respectively), also age ≤ 40 years was independently associated with NDI (β = 5.40, p = 0.002).
Conclusion Three-planar AAI should be reconstructed by C1 LMS-C2 PS fixation, while sagittal or coronal AAI could be corrected by C1 LMS-C2 TLS fixation. PROs may improve after atlantoaxial reconstruction in patients with chronic AAI. The C1–2 Cobb angle is an independent predictor of PROs after correcting chronic AAI, as is age ≤ 40 years for postoperative NDI.

Abstract
Several operative treatments have been explored to treat patients with progressive or symptomatic osteonecrosis of the talus, aiming to alleviate pain and restore mobility. Because most affected patients are typically younger and more active individuals, joint preservation techniques have received increasing attention. Core decompression, either through an open or percutaneous drilling approach has been used. Similarly, nonvascularized and vascularized bone grafts have been used in clinical practice with varying results. Owing to the relative paucity of studies, in this review we aimed to investigate the use of (1) core decompression and (2) bone grafting for treating osteonecrosis of the talus.

Abstract
Vascularized bone grafting for talar avascular osteonecrosis is indicated for patients with modified Ficat and Arlet stage I to III disease with minimal subchondral collapse. Outcomes may be more durable than core decompression alone, especially in patients with more advanced disease. Our preferred method, described in this article, involves core decompression followed by use of a vascularized cuboid pedicle graft placed in the defect. Outcomes reported in a small case series have been encouraging, with more than 80% of patients requiring no further surgery.

Abstract
BACKGROUND: Third generation total talar prostheses (TTPs) are viable options for talar avascular necrosis (AVN) in the absence of neighboring joint pathology. The use of modern three-dimensional (3D) printing allows the production of custom implants that exactly mimic the patient's anatomy. The aim of this study is to determine the accuracy of 3D printing in reproducing a synthetic talus and, in doing so, restoring more normal anatomical relationships. We hypothesize that this mode of replication will restore and maintain normal radiographic alignment of the ankle, subtalar, and forefoot joints in the setting of talar AVN. METHODS: A retrospective analysis was performed on all patients undergoing TTP implantation for the treatment of talar AVN between 2016 and 2017. Radiographic measurements were taken preoperatively and postoperatively to determine native talar dimensions, TTP implant dimensions, and the corresponding radiographic alignment about the forefoot, hindfoot, and ankle. RESULTS: A total of 14 patients were identified in our cohort. Talar arc length and width were not found to be significantly changed; however, talar height was significantly increased with use of TTP. Five alignment dimensions were measured, of which, only talar tilt angle was significantly changed. Instances of Meary's angle correction were observed in cavus and planus foot deformity. CONCLUSION: As a proof of concept, 3D-printed TTP was successful in restoring talar height and talar tilt in the setting of AVN. Additionally, the procedure maintained normal alignment in nonpathological joints. TTPs, based on our cohort, are a viable option to restore more normal anatomical alignment. LEVELS OF EVIDENCE: Level IV: Case series.

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
Avascular necrosis (AVN) of the talus can be a cause of significant disability and is a difficult problem to treat. The most common cause is a fracture of the talus. We have done a systematic review of the literature with the following aims: (1) identify and summarize the available evidence in literature for the treatment of talar AVN, (2) define the usefulness of radiological Hawkins sign and magnetic resonance imaging in early diagnosis, and (3) provide patient management guidelines. We searched MEDLINE and PUBMED using keywords and MESH terminology. The articles' abstracts were read by two of the authors. Forty-one studies met the inclusion criteria of the 335 abstracts screened. The interventions of interest included hindfoot fusion, conservative measures, bone grafting, vascularized bone graft, core decompression, and talar replacement. All studies were of Level IV evidence. We looked to identify the study quality, imprecise and sparse data, reporting bias, and the quality of evidence. Based on the analysis of available literature, we make certain recommendations for managing patients of AVN talus depending on identified disease factors such as early or late presentation, extent of bone involvement, bone collapse, and presence or absence of arthritis. Early talar AVN seems best treated with protected weight bearing and possibly in combination with extracorporeal shock wave therapy. If that fails, core decompression can be considered. Arthrodesis should be saved as a salvage procedure in late cases with arthritis and collapse, and a tibiotalocalcaneal fusion with bone grafting may be needed in cases of significant bone loss. Role of vascularized bone grafting is still not defined clearly and needs further investigation. Future prospective, randomized studies are necessary to guide the conservative and surgical management of talar AVN.
