This is a case report of a 52-year-old woman who sustained a medial subtalar dislocation with fracture of the posterior process of the talus in a traffic accident. After closed reduction of the subtalar dislocation, tomography demonstrated that the talus fracture involved the entire posterior process and the posterior portion of the talar body. The fracture of the talus was treated with an open reduction and miniscrew fixation. At follow-up examination 32 months later, the functional and radiographic results were graded as good. The proposed mechanism of this case was a forced plantarflexion and inversion acting simultaneously on the subtalar joint. This was different from an isolated medial subtalar dislocation, which was caused by an inversion.
这是一例52岁女性的病例报告，该患者在交通事故中发生距下关节内侧脱位并伴有距骨后突骨折。距下关节脱位闭合复位后，断层扫描显示距骨骨折累及整个后突及距骨体后部。距骨骨折采用切开复位和微型螺钉固定治疗。32个月后的随访检查显示，功能和影像学结果评定为良好。该病例推测的机制是同时作用于距下关节的强迫跖屈和内翻。这与单纯由内翻引起的距下关节内侧脱位不同。
