Abstract
|
|
|
|
Guyon’s canal syndrome is a compression neuropathy of the ulnar nerve that occurs at the wrist. Compression can be caused by many conditions, such as benign tumors, repeated occupational trauma, vascular lesions, fractures of the carpal bones, rheumatoid arthritis and anomalous hypothenar muscle at Guyon's canal. Here, the authors report a case of compression neuropathy of the ulnar nerve by the accessory abductor digiti minimi muscle (AADM), one of the anomalous hypothenar muscles, at Guyon's canal. The case report is accompanied by a literature review.
