Subtalar dislocation is the simultaneous dislocation of the distal articulations of the talus at both the talocalcaneal and talonavicular joints. It can occur in any direction and can always produce significant deformity. The medial dislocation is most common. Less common presentations are lateral, anterior, and posterior dislocations. These dislocations are associated with osteochondral fractures. Closed reduction and immobilization remain the mainstays of treatment. Proper radiographs and computed tomography scan confirm the postreduction alignment stability of subtalar joints and intraarticular fracture fragments. We report a case of anteromedial subtalar dislocation with no osteochondral fracture fragments in a 25-year-old man.
距下关节脱位是距骨远端关节在距跟关节和距舟关节同时发生的脱位。它可向任何方向发生,且总会导致明显畸形。内侧脱位最为常见。外侧、前侧和后侧脱位则较少见。这些脱位常伴有骨软骨骨折。闭合复位和固定仍是主要的治疗方法。合适的X线片和计算机断层扫描可确认距下关节复位后的对线稳定性及关节内骨折碎片情况。我们报告一例25岁男性前内侧距下关节脱位且无骨软骨骨折碎片的病例。
