Although it took nearly 6 months to obtain complete flexion of the middle finger, powerful extension of the IP joint was obtained rather quickly in two cases. Surgery is performed through 4 primary incisions: a volar oblique incision in the distal palmar crease at the base of the long and ring fingers, a volar transverse incision at the mid-forearm, a dorsal transverse incision over the midshaft of the third metacarpal, a dorsal forearm transverse incision opposite to the volar forearm incision to shuttle the FDS tendon.The FDS donor tendons to the long and ring fingers are isolated first.Any adhesions between the FDS and flexor digitorum profundus are divided.The FDS tendons are left in the wounds until later to prevent desiccation.On occasion, the FDS tendons can become caught in the carpal canal during harvesting and will need to be pulled back into the distal palmar incision for further lysis of connections between the FDS and flexor digitorum profundus tendons.A wide window, not a slit, is cut in the interosseous membrane to pass 1 of the FDS tendons.A counter incision in the dorsal forearm is made with use of a long, curved clamp through the interosseous membrane. The action of the EDS is to extend the fingers.
