Snapping Triceps Syndrome
Snapping and pain at the medial elbow can be caused by a snapping of the triceps tendon and muscle belly. It can be accompanied by a shooting pain in the distribution of the ulnar nerve. Eccentric loading of the triceps tendon is the most specific test to confirm a snapping triceps syndrome. Two snaps may be experienced during clinical exam. A first snap occurs at around 90°. This is the ulnar nerve subluxating out of its groove. A second snap usually occurs at around 115° when the triceps dislocates over the medial epicondyle. Surgical treatment consists of an anterior transposition of the ulnar nerve and removal of the medial part of the triceps.
