Abstract

The elbow joint is the articulation of the humerus with the radius and the ulna; since it permits only flexion and extension, it belongs to the hinge or ginglymus variety. The trochlea and the capitellum of the humerus articulate respectively with the trochlear notch of the ulna and the head of the radius. The trochlea of the humerus is grasped by the trochlear (semilunar) notch of the ulna, and the capitellum of the humerus rests on the upper surface of the head of the radius. Some anatomists prefer to consider the elbow joint as the result of 3 separate joints having one synovial cavity: namely, the humeroulnar, the humeroradial and the superior radioulnar joints. Here the elbow joint will be considered as having humeroulnar and humeroradial parts, and the superior radioulnar joint will be discussed as a separate joint communicating with the other two.
