The wrist joint surfaces are formed by the radius, ulna, and carpal bones. The surfaces are covered by cartilage. Certain conditions may indicate the need for a replacement for the wrist joint such as: osteoarthritis (shown), persistent pain, severe loss of wrist function, and certain types of fractures. A replacement joint can help alleviate pain and improve function. The replacement joint usually has two parts that replace the joint surfaces and is made of a combination of metal and plastic.
