Transtibial amputation for sciatic nerve loss. Saphenous sensate residual limb

After permanent loss of the sciatic nerve, most patients eventually have problems with the insensate skin and need transitibial amputation. The authors have designed a long medial sensate myocutaneous flap down to the foot based on the saphenous branch of the femoral nerve that resulted in good sensation over the entire transtibial residual limb.
