Wrist

The wrist is a multidirectional hinge joint located between the forearm and the hand. Ten bones form the complex wrist joint and include: the ulna styloid which is the bottom portion of the ulna, one of two bones of the forearm; the distal radius which is the bottom portion of the radius, the other bone of the forearm; and the eight carpal bones that are arranged in two parallel rows. Because of this architecture, the wrist is an extremely flexible joint and allows for a wide range of motion in multiple directions.

Many wrist injuries can be managed non-operatively but severe fractures and dislocations often require surgery.
