Finger joint arthroplasty is a method of replacing defective and diseased delicate finger joints. Multiple new finger joints have been introduced to replace function of the fingers. The ideal joint for replacement arthroplasty should have complete fixation in the long shafts of the bones in the hand and fingers, and a hinge that is durable. The design proposed here will produce these ideal conditions. Polyetherurethane-Terephthalate has those particular characteristics. Long term implantation in man has shown that bones ingrowth is feasible. The experimental work presented, suggest the cloth mesh part can be used for joint replacement as a hinge, because it withstood the mechanical changes. There was no material fracture noted, but the mechanical changes were basically of fraying, crazing, and fragmentation. Over 6 million cycles were used. The results in hand surgery is an integral part of this fast developing field.
