Ulnar Artery: The ulnar artery travels next to the ulnar nerve through Guyon’s canal in the wrist. The in vivo isometric point of the lateral ligament of the elbow. This bony prominence located just above the elbow on the inside is where the muscles that bend the fingers and wrist come together in one tendon to attach to the humerus. This is the large muscle on the front of the arm above the elbow that allows elbow supination, rotation of the elbow. The lateral (radial) collateral ligament (LCL/RCL) complex is a major lateral stabilizer of the elbow joint and resists varus stress. The ulnar collateral ligament (UCL, also known as medial collateral ligament) is located on the medial side of the elbow.The UCL complex comprises three ligaments: the anterior oblique, posterior oblique and transverse ligaments. These muscles of the forearm attach to the medial epicondyle enabling flexion of the hand and wrist. Suite 301 Milwaukee, The Humerus (upper arm bone) forms the upper portion of the joint. Three bony structures create multiple articulations within the elbow complex.
