Elbow: the trochleogingylomoid joint.
More complex than a hinged joint, the elbow provides flexion-extension as well as pronation-supination. A unique arrangement of joint surfaces, soft tissue restraints, and muscle forces provides the mobility and stability of this joint. Understanding basic elbow biomechanics will assist the musculoskeletal radiologist in evaluations of this joint.
