The radial collateral ligament (RCL) is a strong, short, thin band of tissue that connects from the humerus (upper arm bone) to the radius (one of two forearm bones). The role of the RCL is to provide stability against inner to outer stress on the elbow.
The radial collateral ligament (RCL), lateral collateral ligament (LCL), or external lateral ligament[Explain 1] is a ligament in the elbow on the side of the radius.
The humeroulnar and the humeroradial joints each have a ligament connecting the two bones involved at the articulation: the ulnar collateral and the radial collateral ligaments. The ulnar collateral ligament extends from the medial epicondyle of the humerus to the coronoid process of the ulna.
The radial collateral ligament (RCL) of the elbow is an essential stabilizing structure located on the lateral (outer) side of the elbow. While it may not be as frequently discussed as the ulnar collateral ligament (UCL), it is equally critical for the overall stability and function of the elbow joint.
The radial collateral ligament (RCL), radial collateral ligament proper or lateral collateral ligament of the elbow is a static lateral stabiliser and a part of the lateral collateral ligamentous complex of the elbow.
Clinically Relevant Anatomy. The elbow joint is stabilized primarily by three ligaments: Medial collateral ligament. Lateral collateral ligament. Annular ligament. The medial and lateral collateral ligaments provide valgus and varus stability, and allow for rotation.
The Lateral collateral ligament of the elbow (LCL) is sometimes also called the radial collateral ligament (RCL). This ligament can become sprained or torn as a result of a sports injury. Because the LCL has an important role in supporting the elbow, injury can lead to elbow instability.
The radial collateral ligament is found on the lateral side of the joint, extending from the lateral epicondyle, and blending with the annular ligament of the radius (a ligament from the proximal radioulnar joint).
Discover the anatomy, structure, and function of the radial collateral ligament of the elbow joint.
The humeroradial articulation is stabilized by the radial collateral ligament. It is a ‘Y’ shaped structure that connects to the lateral epicondyle via the long arm of the ‘Y’, and the annular ligament of the radius by the short arms of the ‘Y’.
