Volume 93, Issue 7 - Sonographic detection of ulnar nerve compression during elbow extension - Video 1 - Ulnar nerve flattening during extension
Ulnar nerve compression commonly occurs during elbow flexion due to its location in the aponeurotic arch of the flexor carpi ulnaris muscle, also referred to as the humeroulnar arcade. Ultrasonography is an easily accessible tool for dynamic examination of the ulnar nerve in different elbow positions. This video gallery presents a rare case of ulnar nerve compression during elbow extension revealed in dynamic ultrasonography.
