Medial epicondylopathy affects which anatomical structure?

• A. Flexor-pronator origin at the medial epicondyle.
• B. Extensor carpi radialis longus at the lateral epicondyle.
• C. Supraspinatus tendon.
• D. Patellar tendon.

Answer: (A)

Medial epicondylopathy is a tendinopathy at the origin of the forearm flexor-pronator muscles where they attach to the medial epicondyle of the humerus. Repetitive wrist flexion and forearm pronation overload this common flexor tendon, leading to degeneration and pain at the medial epicondyle. That’s why the affected structure is the flexor-pronator origin at the medial epicondyle. The extensor carpi radialis longus originates at the lateral epicondyle and is associated with tennis elbow, not this condition; the supraspinatus tendon is in the shoulder, and the patellar tendon is in the knee.
