Which chronic condition causes elbow pain due to excessive forearm motions such as pronation and supination?

• A. Golfer's Elbow
• B. De Quervain's Tenosynovitis
• C. Tennis Elbow
• D. Ganglion Cyst

Answer: (C)

The main idea here is a chronic overuse injury of the elbow from repetitive forearm movements that stress the tendon origins on the outer elbow. In tennis elbow, the forearm extensor muscles, especially those near the lateral epicondyle, are repeatedly activated during actions like wrist extension and forearm rotation (pronation and supination). Over time this causes microtears and degeneration at the tendon origin, leading to pain on the outer (lateral) elbow that can worsen with gripping or lifting. That’s why this condition best fits the description. Other options don’t align with the elbow-area overuse pattern: Golfer’s elbow (medial epicondylitis) involves the inner elbow and flexor-pronator tendons; De Quervain’s tenosynovitis affects the thumb-side tendons at the wrist; a ganglion cyst is a fluid-filled lump that doesn’t specifically originate from repetitive forearm rotation at the elbow.
