Aberrant Abductor Digiti Minimi Muscle Found during Open Surgical Decompression of the Carpal Tunnel: Case Report
نویسندگان
چکیده
Herein, we present an interesting case of an aberrant hypothenar muscle found during carpal tunnel decompression. The variant muscle arised from the voloradial antebrachial fascia and coursed over the ulnar artery and nerve in the Guyon canal, and inserted into the ulnar aspect of the hypothenar. Tension on the muscle belly provided slight abduction of the fifth metacarpophalangeal joint, which confirmed it to be an aberrant abductor digiti minimi muscle. We also discuss different variations of this muscle and emphasize its potential clinical implications.
