a Probe position for localisation of the ulnar nerve at the elbow. b The nerve (arrowhead) is localised in its short axis within the cubital tunnel between the medial epicondyle (ME) and olecranon process (olec). c MR image showing the normal ulnar nerve (yellow arrow) in the cubital tunnel: medial epicondyle (M) and olecranon process (O) forming the medial and lateral walls, Osborne’s ligament (red arrow) forming the roof and the floor being formed by the joint capsule of elbow and the medial collateral ligament (red arrowhead)
