Prostheses, Joint, Elbow, Ulnar Component

Definition : Implantable prostheses designed to replace the upper end of the ulna at the articulation point. These prostheses provide a partial substitution of the elbow articulation; they typically consist of a short stem that is anchored in the hollow center of the ulna (i.e., the ulnar component) with a hollow end that fits in the humeral component hinge at the articulation point. Made of metal or a combination of metal and polymeric materials, the prostheses may be intended for implantation with or without bone cement. Ulnar component elbow joint prostheses are used in patients who suffer from osteoarthritis or rheumatoid arthritis, as well as after trauma (e.g., fracture).
