Conditions of the Hand and Upper Extremities

The hand and upper extremity is a unique and complex structure. In fact, approximately 25% of the bones in our bodies are found in our hands alone. Small bones called carpals, metacarpals, and phalanges make up wrist, palm, and fingers respectively. The two long bones of the lower arm, called the radius and ulna, meet at the hand to form the wrist joint. There are no muscles in our fingers. Instead, tendons in our fingers are powered by 17 muscles in the palm and 18 muscles in the forearm. A complex bundle of nerves travel down the arm, through the carpal tunnel in the wrist, and into the hand. Each nerve provides sensation for different parts of the hand. Altogether, 27 bones, 123 named ligaments, 29 major joints, and 48 named nerves make up the anatomy of the hand and wrist.
