They provide mobility for the hand in space by shortening and lengthening the upper extremity. Elbow Joint Synovial joint Junction between the arm and forearm Posterior view 6. 3. Anatomy and biomechanics of the elbow joint. The biomechanics of the elbow joint can be divided into kinematics, stabilizing structures in elbow stability, and force transmission through the elbow joint.

These are due, in large part, to the fact that the elbow is a complex trochoginglymoid joint closely surrounded by important neurovascular structures including the medial, ulnar, and radial nerves as well as the brachial artery. Together with a network of capsuloligamentous structures, elbow flexion and forearm rotation are permitted. or the forearm.

Loss of elbow function can severely affect activities of daily living. The elbow joint is a synovial joint found in the upper limb between the arm and the forearm.It is the point of articulation of three bones: the humerus of the arm and the radius and the ulna of the forearm.. • The proximal radioulnar joint consitutes the forearm which when working in conjunction with the elbow joint premits approx 90 degree of pronation and 80 degree of supination. The elbow, a synovial hinge joint, is a common site of disease. Major Lines in X ray joint.
Ultrason ography (US) has become an important imaging modality for evaluating pathologic conditions of the elbow. Fornalski S(1), Gupta R, Lee TQ. X ray Projections. Conclusion. ELBOW JOINT Type - Synovial / Hinge and - compound as it has two articulations i)humero – ulnar & ii)humero – radial Articular surfaces 1. Elbow Joint Three articulations 1.Humerus and Ulna 7.
