  • Implantable prostheses designed for total replacement of the elbow joint. These prostheses typically consist of a combination of a humeral component (consisting of a long stem that anchors it in the hollow center of the humerus at one end and a hinge with a bearing and pin at the articulation point) and an ulnar component (consisting of a shorter stem that anchors it in the hollow center of the ulna with a hollow end that fits in the humeral component hinge at the articulation point); they may include also a radial head component to prevent instability and decrease stress in the elbow articulation. Total elbow joint prostheses made of metal or a combination of metal and polymeric materials with different shapes and technologies are available; the prostheses may be intended for implantation with or without bone cement. Total elbow joint prostheses are used in patients who suffer from osteoarthritis or rheumatoid arthritis, as well as after trauma (e.g., fracture).
