The lateral epicondyle is which option?

• A. Lateral epicondyle
• B. Olecranon
• C. Radial head
• D. Medial epicondyle

Answer: (A)

The lateral epicondyle is a bony prominence on the outer (lateral) side of the distal humerus at the elbow. It marks the lateral aspect of the elbow and serves as the attachment for the common extensor muscles. The olecranon is the posterior projection of the ulna, the radial head is the proximal end of the radius that articulates with the capitulum, and the medial epicondyle is on the inner side of the distal humerus. So the lateral epicondyle is specifically the lateral bump on the distal humerus.
