The common flexor tendon attaches to what bony landmark?

• A. Medial epicondyle
• B. Lateral epicondyle
• C. Olecranon
• D. Coronoid process of ulna

Answer: (A)

The key idea is the shared origin of the forearm flexors. The common flexor tendon anchors to the medial epicondyle of the humerus, a prominent bump on the inner elbow. From this tendon arise several superficial flexor muscles, including the pronator teres, flexor carpi radialis, palmaris longus, and flexor digitorum superficialis. Because of this shared origin, problems at this site are often labeled as medial epicondylitis, highlighting the attachment point. The lateral epicondyle, in contrast, is where the common extensor tendon attaches, powering the extensors. The olecranon and coronoid process are parts of the ulna involved with other attachments and joints, not the common flexor tendon. So the medial epicondyle is the correct landmark.
