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.
