Which description matches excessive pronation and supination activities of the forearm leading to elbow pain?

• A. Tennis Elbow
• B. Carpal Tunnel Syndrome
• C. Dupuytren's Contracture
• D. Ganglion

Answer: (A)

Excessive forearm rotation with the elbow in use stresses the tendons that attach at the outer (lateral) elbow. Repetitive pronation and supination, especially with wrist extension or gripping, can cause microtrauma to the extensor muscle origin at the lateral epicondyle. That pattern leads to pain on the outside of the elbow and is classic for tennis elbow, medically known as lateral epicondylitis. The other conditions don’t describe this elbow-focused overuse pattern: carpal tunnel syndrome involves median nerve compression at the wrist with hand numbness or tingling; Dupuytren's contracture is thickening of the palmar fascia leading to finger flexion contractures; a ganglion is a cyst arising from a joint or tendon sheath, usually near the wrist.
