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.

Abductor Digiti Minimi Muscle

This paper describes four cases of ulnar tunnel compression syndrome caused by the accessory abductor digiti minimi muscle and stresses on the observation that wrist trauma could be an important precipitating factor. Possible pathophysiological explanations of this phenomenon are offered and the anatomy of the accessory abductor digiti minimi muscle is reviewed.

Simple Decompression

The role of in situ decompression in patients with severe ulnar nerve compression is still controversial. Thirty patients with severe ulnar nerve compression confirmed clinically and electrophysiologically underwent simple decompression. The mean age of the patients was 58 (range 26–87) years. Through incisions ≤4 cm the nerves were fully visualized and decompressed. Outcome was measured prospectively using Modified Bishop’s score (BS), grip and pinch strengths and two-point discrimination (2PD). Significant improvement in power (p = 0.01) and pinch grip (p = 0.001) was noted at 1 year. The grip strength continued to improve up to 1 year. According to the BS, 24 patients (80%) had good to excellent results at 1 year. Minimally invasive in situ decompression is technically simple, safe and gives good results in patients with severe nerve compression. The BS and 2PD were more reliable than grip strength in assessing these patients at follow-up.

Ulnar Nerve Compression

Ulnar nerve compression causing clinical symptoms is a common occurrence. There are numerous conditions that can cause compression. Recently two very interesting and unusual etiologies were seen at the Plastic Surgery service. Leprosy causing ulnar nerve compression is a rare occurrence in a Canadian hospital, and so is a case of palmar mycotic aneurysm in the postantibiotic era.
