During an investigation performed on cadaver forearms in the anatomy department, an unusual insertion of the abductor pollicis longus (APL) muscle together with the extensor pollicis brevis (EPB) muscle was encountered unilaterally in a 40-year-old male cadaver forearm. APL originated from the posterior ulnar surface distal to the anconeus, the adjoining interosseous membrane and middle third of the posterior radial surface. It lay distal to the supinator muscle and close to the EPB, while the EPB arose from the posterior radial surface and from the adjacent interosseous membrane. These muscles were inserted to the palmar side of the base of the first metacarpal bone together. To our knowledge, this variation has not been cited in recent medical literature.
在解剖学系对尸体前臂进行的一项研究中，在一名40岁男性尸体的前臂中单侧发现了拇长展肌（APL）和拇短伸肌（EPB）的异常附着情况。APL起自尺骨后表面远侧的肘肌、相邻的骨间膜以及桡骨后表面中1/3处。它位于旋后肌的远侧且靠近EPB，而EPB起自桡骨后表面和相邻的骨间膜。这些肌肉共同附着于第一掌骨基部的掌侧。据我们所知，这种变异在最近的医学文献中尚未被提及。
