Prostheses, Joint, Finger/Thumb
Definition : Implantable prostheses designed to replace one of the interphalangeal joints of a finger or thumb. These prostheses typically consist of articulated silicone or, less frequently, ceramic or metal components with a flat end and a stem. The prosthesis has stems at both ends for introduction into the hollow marrow cavity previously made in bones that form the articulation. Prostheses that permit constrained, semiconstrained, or unconstrained hinged movement of the joint are available. Finger/thumb joint prostheses are used in patients who suffer from osteoarthritis or rheumatoid arthritis; the prostheses may also be implanted to prevent dislocation of the finger or thumb joints. Prostheses for finger and thumb articulations are available in a variety of sizes; marble-like spherical prostheses that are intended to fit between notches cut in thumb joint bones are also available.
