  • Title: Incidence of anatomic variants in Guyon's canal.
    Author: Dodds GA, Hale D, Jackson WT.
    Journal: J Hand Surg Am; 1990 Mar; 15(2):352-5. PubMed ID: 2324469.
    Abstract:
    This study was undertaken to determine the frequency of variations involving the anatomy of Guyon's canal. A series of 58 wrist dissections revealed a 22.4% incidence of anomalous muscles and a 1.7% incidence of anomalous nerve paths. The relationship of the deep branch of the ulnar artery to the superficial and deep branches of the ulnar nerve was found to vary. Accessory muscles passing through Guyon's canal are common, and are often found bilaterally. Aberrant branching of the ulnar nerve in this area is rare.
