Abstract
The elbow can be simplified to a joint between the distal humerus and proximal ulna and radius. The articular surfaces of the humerus are formed of two components: the trochlea and the capitellum, which articulate with the ulna and radius, respectively. The trochlea articulates with the ulna and is covered by articular cartilage over an arc of 300°. The radial head articulates with both the radial notch of the ulna and the capitulum of the humerus. Articular cartilage covers the concave surface of the radial head and an arc of 280° of the rim. The proximal ulna consists of the olecranon and the anterior surface of the ulnar notch. The notch is covered by articular cartilage, except for the mid portion, which is usually covered by fatty tissue. The distal end of the ulnar notch is the coronoid process.
