The flexor digitorum profundus (FDP) is a muscle attached to a bone (ulna) in the forearm. The FDP muscle helps to bend the four fingers of the hand. The FDP works together with bands of fibrous tissue (tendons) that attach to the finger joints. The tendons start at the wrist and cross the palm, and then spread out to the fingers.
