Abstract

An accessory palmaris muscle that arose from the base of the fifth metacarpal passed proximally and inserted into the palmaris longus tendon. In its course it compressed the ulnar nerve and vessels. It was detached proximally and folded on itself to provide hypothenar bulk. The entrapment symptoms were relieved.

摘要

一条起自第五掌骨基部的副掌肌向近端走行，止于掌长肌腱。在其走行过程中，它压迫尺神经和血管。在近端将其分离并自身折叠，以增加小鱼际的体积。卡压症状得以缓解。
