Artificial replacement for human finger‐joints, including the thumb.
A surgical procedure to remove diseased parts of the finger joint, usually the knuckle, and replace it with a prosthesis. The purpose of the procedure is to replace a finger joint that has been removed due to severe pain, deformity, and loss of function, generally as a result of arthritis. Polymer finger joint replacements offer relief from pain and an improved range of motion for most people, as well as improved appearance in the finger.
