Abductor Digiti Minimi Muscle

AbstractAnomalous hypothenar muscles in the wrist are relatively common with 47% prevalence, and their possible consequences associated with Guyon's canal are well known. The accessory of the abductor digiti minimi muscle (ADM) is known to be one of the causes of ulnar tunnel syndrome or ulnar artery thrombosis. A unique ADM was found in the volar wrist region of an 87-year-old male cadaver passing through Guyon's canal.

Anomalous Branch

We present a case of isolated Abductor Digiti Minimi (ADM) palsy caused by an anomalous branch from the ulnar artery. Electrophysiology suggested selective involvement of the motor branch to the ADM in the Guyon's canal. Surgical exploration revealed an anomalous branch of the ulnar artery causing a pincer effect on the nerve to the ADM. Division and ligation of this branch effectively decompressed the nerve and the patient recovered satisfactorily. This report highlights the need to consider vascular aberrations as a differential diagnosis for ulnar neuropathy in Guyon's canal.

Anomalous variations of abductor digiti minimi are commonly found at Guyon's canal but rarely cause ulnar nerve compression. We report such a case with particular emphasis on the effectiveness of ultrasound to detect and delineate anatomical structures in this region.
