The Relationship Between the Ulnar Nerve and the Cubital Tunnel with Elbow Motion Medscape

Description: Neural traction may be an important cause of cubital tunnel syndrome, according to researchers at the Washington University School of Medicine in St. Louis. To study the etiology of cubital tunnel syndrome (compression of the ulnar nerve at the elbow), 23 upper extremity cadaveric specimens were studied using a combination of magnetic resonance imaging (MRI), dynamic three dimensional MRI reconstruction, and intraneural and extraneural pressure measurements in varying degrees of elbow flexion.
