The medial epicondyle is displaced with a sliver adjacent bone, representing an avulsion fracture. Marked adjacent soft tissue swelling and joint effusion. Alignment is otherwise within normal limits.

Case Discussion

Medial humeral epicondyle fractures are common, second only to supracondylar fractures in terms of frequency. These tend to occur from vaglus or extension loading, with medial collateral ligaments and/or common flexor origin tendons avulsing the medial humeral epicondyle.
