Snapping triceps syndrome

Discussion:

Adult male presented with medial elbow trauma with pain. Ultrasound shows ulnar nerve anterior to the medial epicondyle of the humerus with elbow extension meaning dislocated ulnar nerve. With elbow flexion, there is triceps dislocation anterior to the medial epicondyle of the humerus. Only one 'snap' could be felt that was due to triceps dislocation. Patient's symptoms were not related to snapping of triceps. Rest of the elbow ultrasound examination was normal.

The case is an asymptomatic/unrecognized snapping triceps syndrome.
