This paper describes a new technique in the repair of the hand defect with digital extensor tendon injury.The anterolateral thigh flap with the thick femoral fascia has been used in the reconstruction of the composite defect of the dorsal hand,especially the defect of tendon.This technique requires short period of treatment and hence causes less damage to the donor site but shows a better recovery of the hand function.A favorable curative effect has been obtained in this patient.
