[Use of free flaps for covering deep burns in functional sites].

From July 1980 to July 1988, 10 free flaps were used to cover deep burn on wrist, elbow, heel and hand. The wounds can be closed in time and the functions can be rehabilitated early. The results were not satisfied if the traditional methods were used to cover the infected and necrotic muscle, tendon, nerve, blood vessel, bone and joint due to electric, hot compressed or flame burns. The choice of using free flaps should be very careful because the operation time is relatively longer, the procedure is more complex, and the general condition of the patient may be interfered. The more serious results may be got if the free flap does not survive. It is recommended to use antero-lateral femoral free flap, because the sites of blood vessels are constant, the donor area can be hidden from view, the thickness and softness are satisfied.
