What condition refers to pain at the lateral epicondyle exacerbated by wrist extension and repetitive motions?

1. Cubital tunnel syndrome

2. Lateral epicondylitis

3. Carpal tunnel syndrome

4. Radial tunnel syndrome

The correct answer is: Lateral epicondylitis

Lateral epicondylitis, commonly known as tennis elbow, is characterized by pain at the lateral epicondyle of the humerus. This condition typically arises from overuse injuries, particularly those involving repetitive wrist extension and gripping motions, which strain the tendons attached to the lateral epicondyle. In individuals experiencing lateral epicondylitis, the pain often intensifies with activities like lifting or extending the wrist. The primary reason this condition is singled out is due to its specific association with wrist extension and the location of pain at the lateral side of the elbow, making it distinct from the other conditions listed. For instance, cubital tunnel syndrome involves compression of the ulnar nerve at the elbow, leading to different pain patterns and symptoms, primarily along the ulnar aspect of the forearm and hand. Carpal tunnel syndrome is related to compression of the median nerve at the wrist, manifesting symptoms like numbness and tingling in the hand rather than localized elbow pain. Radial tunnel syndrome, while it may involve pain in the lateral aspect of the forearm, generally describes pain due to compression of the radial nerve and does not typically present with the same hallmark symptoms as lateral epicondylitis. Understanding these distinctions helps clarify why lateral
