Introduction
The radial collateral ligament of the elbow joint (external lateral ligament) is a short and narrow fibrous band, less distinct than the ulnar collateral.
The radial collateral ligament of the elbow joint is visible near the center.
Attachments
This ligament is attached above to a depression below the lateral epicondyle of the humerus, and below below to the annular ligament (with some of its most posterior fibers passing over that ligament), to be inserted into the lateral margin of the ulna. It is intimately blended with the tendon of origin of the supinator.
