The fasciocutaneous flap is very useful in the repair of soft tissue defects on the lower leg. It is easy to design and construct large flaps that are safe because of the good circulation. The operating time is short for an experienced surgeon and no extra equipment is needed. It is perfectly possible to carry out surgery on the underlying bones at the same time. The postoperative treatment is simple for both the patient and the staff. The surgical technique is described and the results of 23 flaps are critically reviewed.
