The Elbow



Figures 4.1 and 4.2 illustrates the surface anatomy of the elbow. The elbow functions as a hinge joint that allows the transfer of kinetic energy from the body to the upper extremity. The joint is composed of three articulations: the trochlea of the humerus articulates with the ulnar notch, the capitellum of the humerus articulates with the radial head, and the radius articulates with the stationary ulna (see Fig. 4.3). The elbow joint is held together by a capsule of connective tissue, which is thickened medially and laterally, where it is called the ulnar and radial ligaments, respectively.
