An anomalous muscle is uncommonly associated with ulnar nerve compression at the wrist. Anomalies of the palmaris longus, abductor digiti minimi, flexor digiti minimi, and flexor carpi ulnaris have been described. Another case is presented in which the anomalous muscle would appear to be a duplication of the palmaris brevis. This muscle has been named the "palmaris brevis profundus."
异常肌肉与腕部尺神经受压的关联并不常见。已描述过掌长肌、小指展肌、小指屈肌和尺侧腕屈肌的异常情况。本文报告另一例病例，其中异常肌肉似乎是掌短肌的重复。这块肌肉被命名为“掌短深肌”。
