Anomalous abductor digiti minimi in Guyon canal: A cadaver study.
A routine cadaver dissection revealed a noteworthy anomalous muscle in the distal anterior forearm. Clinicians should be aware of this finding and consider it as a differential diagnosis in patients with wrist disorders such as ulnar tunnel syndrome from occlusion of the ulnar canal. A space-occupying lesion, such as the anomalous muscle found in this dissection, is an important potential source of ulnar canal obstruction.
