Elbow anatomy, biomechanics and clinical examination
5 天之前 · The elbow joint is formed by the distal humerus, proximal radius and ulna, which form part of the static elbow stabilizers. Three separate articulations occur within the elbow: the humero-ulnar, humero-radial, and proximal radio-ulnar joints, which allow for flexion and extension of the elbow, as well as pronation and supination of the forearm.
