Abstract :
Artificial finger joint design has been developed through different stages through the past. PIP (proximal interphalangeal) and MCP(metacarpophalangeal) artificial finger joints have come to replace the amputation and arthrodesis options; although, these artificial joints are still facing challenges related to reactive tissues, reduced range of motion, and flexion and extension deficits. Swansonsilicone artificial finger joints are still common due to the physician’s prefer ability of silicone with the dorsal approach duringoperation. Nevertheless, other artificial finger joints such as the pyrocarbon implant arthroplasty have also drawn the interests of practitioners. Artificialfinger joint has been classified under three major categories which are constrained, unconstrained, and linked design. There are also challenges such as concerns of infections and articular cartilage necrosis associated with attemptedretention of vascularity. In addition, one of the main challenges facing the silicone artificial finger joints is the fracture occurringat the distal stem with the hinge. The aim of this paper is to review the different artificial finger joints in one paper as there are few old review papers about them. Further studies need to be done to develop the design and materials of the pyrocarbon and silicone implants to increase the range of motion associated with them and the fatigue life of the silicone implants.
