The increased knowledge of the cutaneous circulation of the body and refinements in surgical technique have provided the basis for the successful microvascular transfer of various muscle, skin and myocutaneous free flap. We have found the tensor fascia lata(TFL) inyocutaneous flap to be reliable one and its transfer as a free flap. The TFL myocutaneous free flap was first introduced by Hill et al in 1978 and our two cases report were first introduced in Korea. Two cases of microvascular TFL myocutaneous free flap transfer were performed at the department of Orthopaedic Surgery of Hanyang University Hospital and satisfactory result was obtained from the one of those.
