Its tendons insert on the base of the distal phalanx. Within the hand, the tendons fan out and enter their respective fibrous flexor sheaths. Flexor tendon injuries are some of the more common injuries, but yet complex injuries managed by hand surgeons. It is in the anterior compartment of the forearm.it is sometimes considered to be the deepest part of the superficial layer of this compartment, and sometimes considered to be a distinct, intermediate layer of this compartment.
Zone is unique in that fdp and fds in same tendon sheath (both can be injured within the flexor retinaculum). Therefore, profundus's tendons go through the tendons of superficialis, and end up attaching to the distal phalanx. A good understanding of the treatment procedures, healing. On the volar aspect of the wrist, the carpal bones form a deep excavation over which the flexor retinaculum arches, creating the carpal tunnel. The vascular anatomy of the flexor digitorum profundus (fdp) tendon insertion is described by using a vascular injection and modified spalteholtz tissue clearing protocol in 36 human cadaver digits.
