SUMMARY: Nerve compression by anomalous muscles located at the wrist and distal forearm is an infrequent condition. Accessory muscles may compress underlying structures in the Carpal Tunnel region or ulnar canal , producing pain and paresthesia. Two cases of ulnar and median nerve compression, caused by prominent accessory muscles at the distal forearm, are described. Literature review is presented.

KEY WORDS: Muscles; Nerve Compression Syndromes; Anatomic Variation.
