Anatomy of the Hand

The human hand consists of several small bones called phalanges, metacarpals and carpals.  The wrist is where the radius and the ulna (the two bones of the lower arm) meet at the hand. 

An area cartilage between the radius and the ulna separates the radioulnar joint from the rest of the wrist, which is contained within a capsule of cartilage, synovial membrane, and ligaments. Radiocarpal ligaments carry the hand along with the forearm in rotational movements, and intercarpal ligaments strengthen the small wrist bones.

The carpal tunnel is an area where several tendons and nerves pass through the wrist. In carpal tunnel syndrome, a narrowing of this opening compresses the nerves and tendons.

Another common problem is pain at the base of the thumb, usually later in life, from arthritis. This can be treated with splints, injections, and possible reconstructive surgery, if needed.

Other common wrist problems include bone fractures, dislocations of the various component joints, and inflamed tendons and ligaments from overuse.
