在对一具成人身体进行常规解剖时，在左侧幻觉区发现了一组腱异常。拇长伸肌主肌腱植入正常，副肌腱位于主腱内侧和外侧。最外侧肌腱起源于多余的肌腹，与拇短伸肌腱汇合形成复合腱。最内侧肌腱穿过跖趾关节，将复合肌腱深接至拇长伸肌腱。一种末端肌腱，由这三个部分组成，插入到近侧拇指指骨上。这种变异可能是由于发育过程中共同伸肌质量的非典型分化引起的，对临床医生进行关节镜检查、肌腱转移和其他外科手术具有特别重要的意义。
During routine dissection of an adult human cadaver, a suite of tendinous anomalies was discovered in the left hallucal region. Whereas the main tendon of the extensor hallucis longus muscle inserted normally, two accessory tendons were found coursing medial and lateral to the main tendon. The most lateral tendon originated from a supernumerary muscle belly and merged with the tendon of extensor hallucis brevis to form a composite tendon. The most medial tendon crossed the metatarsophalangeal joint and joined the composite tendon deep to the tendon of extensor hallucis longus. A terminal tendon, consisting of these three contributions, inserted upon the proximal hallucal phalanx. This variant likely arose due to atypical differentiation of the common extensor muscle mass during development, and is of particular significance to clinicians performing arthroscopy, tendon transfers, and other surgical procedures.
