Ulnar nerve compression at Guyon's canal by an anomalous abductor digiti minimi muscle: the role of ultrasound in clinical diagnosis.
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.
