The anatomy of the hand is efficiently organized to carry out a variety of complex tasks. These tasks require a combination of intricate movements and finely controlled force production.

The shape of the bony anatomy in conjunction with the arrangement of soft tissues contributes to the complex kinesiology of the hand Injury to any of these structures can alter the overall function of the hand and therefore complicate the therapeutic management.

The anatomy of the volar aspect of the fingers includes the flexor digitorum superficialis and profundus tendons. Each flexor superficialis tendon splits at the proximal interphalangeal joint, with each limb coursing to each side of the flexor digitorum profundus tendon to insert on the middle phalanx.

At the dorsal aspect of each finger, the extensor digitorum tendon attaches to the middle phalanx as a central band, while slips of the extensor tendon that contribute to the lateral bands attached to the distal phalanx.
