Ulnar Collateral Ligament of Elbow

The ulnar collateral ligament of the elbow, which is made up of a thick band of fibrous connective tissue, is located in the medial wall of the elbow capsule. The front of the ligament connects the medial epicondyle of the humerus (upper arm bone) to the medial margin of the coronoid process of the ulna. Its back portion is attached to the medial epicondyle of the humerus and to the olecranon process of the ulna.
