Ligament Collateral Radial

The radial collateral ligament is an anatomical structure that connects the radius to the skeleton of the ulna.

This ligament plays an important role in maintaining the stability and strength of the shoulder, forearm and hand. It also helps keep your hand in the right place when moving.

The collateral bone ligament is a dense tissue formed by fibrous fibers and capsules. This ligament consists of four parts: posterior, lateral, external and internal.

The posterior ligament is located near the inner edge of the elbow joint. The primary function of the posterior ligament is to maintain stability at the ulnar junction and protect the medial epicondyle of the radius. The posterior ligament is also involved in flexion and extension of the forearm.

The collateral ligament, the second largest ligament of the elbow joint apparatus, is located closer to the inside of the elbow joint. The lateral ligament prevents the radius from moving backward relative to the ulna, and therefore prevents the middle third of the forearm from moving laterally. It also increases medial rotation of the forearm during elbow flexion, promotes active flexion of the forearm in the frontal plane, and is more actively involved in extension of all three movements of the forearm at the elbow joint.

The external and internal ligament are located at the angles formed by its inner edge, the olecranon process and the lateral periosteal eminence of the radius in front, and the posterior interosseous ligament on the posterior edge.

The collateral ligaments provide additional stability to the shoulder, preventing it from shifting during lateral movements of the shoulder joint. Normally, at the top of the joint is the acromion, which is attached to the collarbone and scapula. When the shoulder joint moves, the acromion slides along the coracoid process of the scapula, thereby
