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...

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...

Dislocation of the talus is a serious and extremely rare injury, with 86 cases reported in the published data in 20 years. The reference standard for case management involves replacement of the dislocated talus to restore the height and function of the tibiotalar joint. The risk of avascular necrosis remains very high, and the standard treatment in such cases is tibiotalar arthrodesis. We report the case of total dislocation of the talus, which was treated with the insertion of a custom total talar prosthesis affixed directly to the tibial cartilage at 6 months after injury...

BACKGROUND: Total ankle arthroplasty (TAA) is an alternative to arthrodesis, but no randomized trial has examined whether a fixed bearing or mobile bearing implant provides improved gait mechanics. QUESTIONS/PURPOSES: We wished to determine if fixed- or mobile-bearing TAA results in a larger improvement in pain scores and gait mechanics from before surgery to 1 year after surgery, and to quantify differences in outcomes using statistical analysis and report the standardized effect sizes for such comparisons...

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...

BACKGROUND: Trauma to the talus can result in fracture, avascular necrosis and structural collapse. Treatment has been limited to surgical fusion and total ankle arthroplasty. Total ankle arthroplasty may not be an appropriate treatment for avascular necrosis while surgical fusion of the joint limits mobility. Custom-made implants have recently been used to address these limitations but have lengthy delays between injury and surgery and higher associated costs. A generic talar prosthesis available in various sizes may serve as a suitable alternative...

Tibiotalocalcaneal arthrodesis is a safe and viable option to treat patients with arthridities affecting ankle and subtalar joints, neuromuscular disorders, avascular necrosis of the talus, failed ankle arthrodesis, instability, and Charcot neuroarthropathy. Choice of incision and fixation is based on deformity, pathology, prior surgery and hardware, and surgeon comfort and preference. Intramedullary nails offer high primary stability, reduce sustained soft tissue damage, and may allow for earlier return to activities than traditional plate or screw constructs...

Total loss of talus due to trauma or avascular necrosis, for example, still remains to be a major challenge in foot and ankle surgery with severely limited treatment options. Implantation of a custom made total talar prosthesis has shown promising results so far. Most important factors for long time success are degree of congruence of articular surfaces and ligamentous stability of the ankle. Therefore, our aim was to develop an optimized custom made prosthesis for total talus replacement providing a high level of primary stability...

INTRODUCTION: Non-or partial weight bearing is frequently the standard treatment after peri-articular lower extremity fractures. Displaced talar neck fractures are severe injuries compromising vascularity of the corpus and consequently are at risk for non-union and avascular necrosis, the main reason to restrict weight bearing for up to three months according to most literature. CASE PRESENTATION: We report a case of a 31-year old male with a high impact car accident...

In this study, we present the case of a 42-year-old man with a fracture and dislocation of the left talus neck, and a fracture of the right talus neck due to a fall. This kind of fracture can be considered rare, and thus few cases have been reported. Fracture fixation was provided through cannulated screws on either side. Splints were removed after 6 weeks, and passive/active joint movement exercises were started. The patient was able to walk with partial weightbearing at 2 months and with full weightbearing at 3 months...

A case of complicated lateral subtalar dislocation is presented and the literature concerning this injury is reviewed. Subtalar joint dislocations are rare and often the result of a high-energy trauma. Complications include avascular necrosis of the talus, infection, posttraumatic osteoarthritis requiring arthrodesis and chronic subtalar instability. Negative prognostic factors include lateral and complicated dislocations, total talar extrusions, and associated fractures. A literature search was performed to identify studies describing outcome after lateral subtalar joint dislocation...

BACKGROUND: Tibiotalocalcaneal arthrodesis with headless compression screws has not been previously reported. We hypothesized that these screws could be suitable for tibiotalocalcaneal arthrodesis because of their special design. This study aimed to evaluate the clinical outcomes of patients undergoing tibiotalocalcaneal arthrodesis with headless compression screws for the treatment of severe arthropathy of the ankle and subtalar joint. METHODS: From 2010 to 2015, 23 patients with severe ankle and subtalar arthropathy underwent tibiotalocalcaneal arthrodesis...

Total talar dislocations, in which the talus is dislodged from all three of its articulations are rare, comprising only 3.4% of all major talar injuries. The most common complications are osteomyelitis and avascular necrosis. The current literature on total talar dislocations is based on small series and case reports. This literature review outlines the anatomy and blood supply to the talus and discusses the mechanism of injury, presentation, treatment and complications associated with total dislocations of the talus...

Talus fractures often lead to late post-traumatic arthrosis. In such cases, the use of latest generation, cementless prostheses has been hindered by the presence of avascular necrosis. We report the case of a 65-year-old patient who presented four years after a talus neck fracture. He had painful ankle arthrosis (AOFAS ankle-hindfoot score 19) and avascular necrosis, with collapse of the entire talar dome. Given the extent of the necrosis, it was decided to cement the talus prosthetic component. One year after the surgery, the patient shows good clinical and radiological results (AOFAS ankle-hindfoot score 87) and is satisfied with the procedure...

We describe a highly selective incision combined with percutaneous manipulation for reduction and internal fixation of talar neck fractures. We retrospectively investigated the clinical data from 29 cases of talar neck fractures treated from January 2009 to June 2013. Fifteen patients (study group) were treated using a 1- to 2-cm limited incision placed on the anteromedial or anterolateral side of the talus, followed by percutaneous reduction and fixation. Another 14 patients (control group) underwent open reduction and internal fixation through a conventional anteromedial or anterolateral approach...

Isolated acute traumatic subtalar dislocations are quite rare. They correspond to talotarsal dislocation, including the talonavicular and talocalcaneal joints. The purpose of the present study was to evaluate the functional and radiologic outcomes of the treatment of acute traumatic isolated subtalar dislocations. The present retrospective study included 13 patients who had sustained isolated subtalar dislocations during a 10-year period. Of the 13 cases, 10 (76.9%) were medial dislocations and 3 (23.1%) were lateral dislocations...
