Document Summary

Complex hinge-pivot joint created by the articulations of the humerus, radius and ulna. All 3 articulations communicate within a single joint capsule: radioulnar joint. Radial notch of ulnar and radial head. Radius crosses over ulna in pronation and back in supination. Radius rotates on its long axis to provide pronation/supination: radiohumeral joint. Head of radius + capitulum of the humerus: humero-ulnar joint. Trochlear of humerus + trochlear notch of ulna. Allows for pronation and supination of the elbow. 2 distinct prominences of the distal humerus and they provide attachment sites for. Lateral (capitulum) condyle tendons and ligaments with associated epicondyles. Coronoid fossa anterior (for the coronoid process of ulna) Olecranon fossa posterior (for the olecranon process of the ulna) Coronoid process located on the anterior portion of the distal end of the trochlear notch. Trochlea is more medial and has an hourglass shape is viewed in the horizontal plane.
