The wrist joint contains the ends of the radius, ulna and eight carpal bones. This joint was designed to help the hand be capable of moving with a wide range of motion and flexibility. The wrist joint is surrounded by two individual bursa. A bursa is a fluid filled sack that serves to reduce friction in the joint. The two major bursae of the wrist are the radial bursa and the ulnar bursa.
