Prostheses, Joint, Wrist, Carpal Trapezium
Definition : Implantable prostheses designed for replacement of the carpal trapezium bone, one of the eight bones of the wrist connecting the bones of the forearm and the bones of the hand at the wrist joint. These devices are typically one-piece prostheses with an intramedullary stem made from polymeric (e.g., silicone elastomer) materials, resembling the shape and characteristics of the natural bone. Carpal trapezium wrist prostheses are mainly used to restore wrist motion and thumb function in patients who suffer from degenerative arthritis or posttraumatic arthritis (e.g., following an old Bennett's fracture).
