This paper describes the biomechanics of the articulations of the elbow joint that is relevant to therapists who design rehabilitation programs for patients following injuries or surgeries to the elbow. It was noted that greater posterior and varus forces of the elbow are encountered with internal rotation of the hand position and, consequently, full forearm pronation. For the distal radioulnar joint, the center of rotation remained relatively fixed about the center of the curvature of the articular surface of the ulna. The ulnar collateral ligament of the human elbow joint. Course Materials About | BIOMECHANICS OF ELBOW JOINT PRESENTED BY:PRATIBHA MOHANTY MPO 1ST YEAR NIOH,KOLKATA 2. Due to this infrequency, many will therapists simply refer out to specialists when these patients present. 2 Motions available at the elbow are flexion and extension, which occur in a plane oriented slightly oblique to the sagittal plane, owing to the angulation of the trochlea of the humerus. Learn faster with spaced repetition. This happens because our bone surfaces articulate at the joint. The idea that the morphology of articular surfaces is strongly related to kinematics can be traced back to the works of MacConaill, 7, 8 Maitland, 10 MacConaill and Basmajian, 9 and Steindler. This course covers the anatomy and arthrokinematics of the elbow, including the humeroulnar joint (HUJ), humeroradial joint (HRJ), and proximal radioulnar joint (PRUJ), which provides a foundation for joint mobilization.
