Abstract
1. A case of compression of the deep palmar branch of the ulnar nerve by an accessory abductor minimi digiti muscle is described. 2. The morphology of abnormal muscles in the hypothenar region is discussed. 3. Five previously reported cases of ulnar nerve compression at the wrist by an anomalous muscle are reviewed. 4. When symptoms are produced by an anomalous hypothenar muscle, they seem to be related to the anatomical site of the muscle and the presence of muscle hypertrophy. Occupational factors may be important in producing this hypertrophy.Keywords
