From 1987, in 4 cases having muscle damage associated with extensive skin defeet, the repair was carried out by anastomosing the neurovascular pedicle of the free latissimus dorsi myocutaneous graft with the host. The patients were followed up from 6 months to 3 years. The muscle power of the injured part following repair had returned to about 4 degrees, and the external appearance and the function were satisfactory. The advantages and disadvantages of this operation, the preparation of the recipient area and the management of the tendon were discussed.
