| Abstract text: | In order to understand the biomechanics of the elbow it is important to understand its anatomy. The elbow joint is actually three separate joints; the ulnohumeral joint, the radiohumeral joint and the superior radioulnar joint. All three joints are enclosed by a single joint capsule. The elbow-joint is a ginglymus or hinge-joint. The trochlea of the humerus is received into the semilunar notch of the ulna, and the capitulum of the humerus articulates with the fovea on the head of the radius. The articular surfaces are connected together by a capsule, which is thickened medially and laterally, and, to a less extent, in front and behind. These thickened portions are usually described as distinct ligaments under the following names:The Anterior Ligament,The Posterior Ligament, The Ulnar Collateral Ligament, The Radial Collateral Ligament.Movement between the ulna and the humerus occurs at the ulnohumeral joint. Movement between the radius and the humerus occurs at the radiohumeral joint and movement between the radius and the ulna occurs at the superior radioulnar joint. Injury can lead to abnormal biomechanics of the elbow that can result in abnormal forces in the elbow. Over time these abnormal forces can cause the articular cartilage of the elbow to wear out prematurely. |
