The os peroneum is an accessory ossicle within the peroneus longus tendon. Prior reports have discussed fracture of the os peroneum with associated tears of the peroneus longus tendon. When the ossicle fractures, there can be varying degrees of retraction of the tendon, which can be diagnosed by malposition of the ossicle or the ossicle fragments. We report a case of a man with recurrent eversion ankle injuries with progressive retraction of a fractured os peroneum, implying injuries to the superior and inferior peroneal retinacula and the peroneus longus tendon.
腓籽骨是腓骨长肌腱内的一个副骨。先前的报告讨论过腓籽骨骨折合并腓骨长肌腱撕裂的情况。当籽骨骨折时,肌腱会有不同程度的回缩,这可通过籽骨或籽骨碎片的位置异常来诊断。我们报告一例男性病例,该患者反复出现外翻型踝关节损伤,骨折的腓籽骨逐渐回缩,提示腓骨上下支持带及腓骨长肌腱损伤。
