Elbow Joint Dysfunction
The elbow joint is composed of three bones - the humerus, radius and ulnar – and three joints.
● Radioulnar Joint: the radioulnar joint is one of two articulations between the radius and the ulnar bones of the forearm. As the two bones run parallel they join both at the elbow and at the wrist. Dysfunction of either of the two joints causes elbow joint dysfunction.
● Humeroulnar Joint: the humeroulnar joint is the joint between the humerus (arm bone) and the ulnar (forearm bone on the little finger side of the arm).
● Radiohumeral Joint: the humeroradial joint is the joint between the humerus (arm bone) and the radius (forearm bone on the thumb side of the arm).
Elbow Joint Dysfunction is the term used to describe a number of elbow joint injuries that affect the function of the elbow. These include traumatic, biomechanical, hormonal, inflammatory or degenerative changes. These injuries may cause hypomobility (less movement) or hypermobility (more movement). This altered function can cause further problems with the surrounding muscles and ligaments resulting in elbow, shoulder, wrist and hand pain.
