Answer

The medial epicondyle is the common origin of the forearm flexor and pronator muscles. The most common site of pathology is the interface between the pronator teres and the flexor carpi radialis origins. [6, 7] The flexor pronator muscle group serves as a secondary stabilizer of the medial elbow, assisting the ulnar collateral ligament (UCL).
