The elbow joint consists of three bones: humerus, ulna, and radius. The main joint is a hinge joint which allows the elbow to straighten and bend. There are also other joints that work to pronate and supinate the hand and allows the elbow bones to slide as bending occurs.

A ligament is a soft tissue that connects a bone to another bone. The ulnar collateral ligament (UCL) connects the ulna to the humerus. It is located on the medial side of the elbow. The UCL acts as the main source of stability for the elbow[1].
