This study describes five bilateral anatomical variations in the feet of a 97-year-old male cadaver. Following routine dissection, all variants were measured and documented. Three accessory tendons and two accessory ossicles were identified. Bilateral accessory tendons were present from the tibialis anterior (type II), peroneus tertius (type III), and peroneus brevis muscles. Accessory tendon length was 36-104 mm and width was 1-3 mm each inserting more distally then the main tendon. Accessory ossicles were identified as an accessory navicular and os peroneum, respectively. Individually, each variation has varying prevalence rates in the literature, but to date, no known studies have been published describing the combined presence of all five bilateral variations. The acknowledgement of multi-variant cases such as this one may be helpful in the clinical setting, particularly for patients with pathology or for those undergoing foot and ankle surgery.
本研究描述了一名97岁男性尸体足部的五种双侧解剖变异情况。经过常规解剖后，对所有变异进行了测量和记录。共识别出三条副肌腱和两块副骨。双侧副肌腱分别来自胫骨前肌（II型）、第三腓骨肌（III型）和腓骨短肌。副肌腱长度为36 - 104毫米，宽度为1 - 3毫米，各自插入位置比主肌腱更靠远端。副骨分别被识别为副舟骨和腓籽骨。就个体而言，每种变异在文献中的发生率各不相同，但迄今为止，尚无已知研究发表描述这五种双侧变异同时存在的情况。认识到这样的多变异病例在临床环境中可能会有所帮助，特别是对于有病理情况的患者或接受足踝手术的患者。
