Impingement exostoses of the talus and fibula following an inversion sprain is an uncommon sequela to the initial injury. Although a high frequency of symptomatic tibial and talar impingement exostoses have been reported, changes on the lateral side of the ankle are more subtle with significant roentgenographic findings rarely seen. The authors present a rare case of impingement exostoses involving both the talus and fibula simultaneously. Arthroscopy visualized the tibiotalar and talomalleolar articulations. It revealed opposing exostoses of the talus and fibula, necessitating surgical resection. Arthroscopy is recommended for difficult diagnostic problems of the ankle and an awareness of the condition of post-traumatic impingement exostoses of the talus and fibula.
内翻扭伤后距骨和腓骨的撞击性外生骨疣是初始损伤罕见的后遗症。虽然已有报道称有症状的胫骨和距骨撞击性外生骨疣发生率较高，但踝关节外侧的变化更为细微，很少见到明显的X线表现。作者报告了1例罕见的同时累及距骨和腓骨的撞击性外生骨疣病例。关节镜检查观察了胫距和距踝关节面。发现距骨和腓骨相对处有外生骨疣，需要手术切除。对于踝关节难以诊断的问题，建议采用关节镜检查，并要认识到距骨和腓骨创伤后撞击性外生骨疣的情况。
