The vertically based deep fascia turnover flap of the leg: anatomic studies and clinical applications.
Although fasciocutaneous turnover flaps are a simple and fast method for covering soft-tissue defects of the lower leg, many reconstructive surgeons have their doubts about them. They revolve around the lack of criteria for safely designing these random-pattern flaps and around the risk of donor site problems. A vertically based deep fascia turnover flap with a paratibial or parafibular pedicle is presented. Anatomic studies of 36 injected lower limbs showed the deep fascia to be supplied by a mean of 61 vessels. As musculofascial, septofascial, and periosteofascial branches, these contribute to a richly anastomosing vascular network within the deep fascia. Along the deep transverse septum at the medial tibial border, the anterior and posterior peroneal septa, and between the anterior tibial and extensor muscles, the fascia is supplied by segmental vessels in a clearly defined arrangement. Pedicled on these vessels, the deep fascia is a useful candidate tissue for transversely oriented turnover flaps. These are particularly well suited for covering pretibial or prefibular soft-tissue defects. Unlike adipofascial turnover flaps, the transversely oriented deep fascia turnover flap keeps its subcutaneous layer with its intact vascular plexus so that the overlying skin is adequately perfused even in patients with sizable flaps or an extremely thin skin. Clinical experience with the vertically based paratibial or parafibular deep fascia turnover flap in six patients confirmed its usefulness for covering small to medium-sized soft tissue defects of the lower leg.
