A prospective study of ultrasound of the ulnar nerve across the elbow in compression neuropathies

Purpose: To clarify how reliable the ultrasound of the ulnar nerve at the elbow is in order to diagnose compression neuropathies, to elucidate some of the underlying mechanisms by investigating the ultrasound properties of the ulnar nerve in patients and their correlation with the electrophysiological findings and to establish the normative data for ultrasound measurements of the ulnar nerve. Material and methods: The ulnar nerve was ultrasound examined with the patient in the supine position with the elbow flexed. We used a linear array transducer, 6/18 MHz and a small pressure to avoid deformation of the nerve…
