BackgroundThe medial sural perforator island flap may be suitable for the reconstruction of postburn knee flexion contractures. However, postburn knee flexion contractures are usually associated with burns of the calf, which is the donor site of the medial sural perforator flap. Thus, there are concerns regarding the safety of raising medial sural perforator flaps from burned calves.MethodsBetween 2005 and 2010, 12 patients (11 males and 1 female) with postburn knee flexion contractures associated with second-degree burns of the calf (that healed by secondary intention) underwent reconstruction using a medial sural perforator island flap (based on the medial sural perforator) or medial sural perforator plus island flap (based on the medial sural perforator and other vessels that are pedicles of the sural flaps).ResultsAll 12 flaps, which ranged in size from 7 to 15 cm in width and from 9 to 23 cm in length, survived completely. Of the 12 flaps, three were medial sural perforator island flaps and nine were medial sural perforator plus island flaps. Of the nine medial sural perforator plus island flaps, two included the lesser saphenous vein, five included the lesser saphenous vein and its accompanying artery, and two included the lesser saphenous vein, the distal sural nerve and their accompanying arteries. Healing of all donor sites was uncomplicated. All patients were completely satisfied with their results.ConclusionsAlthough this series is not large, the authors are convinced that some reliable medial sural perforators are usually present under second-degree burned calf skin that healed by secondary intention, and that the medial sural perforator island flap or the medial sural perforator plus island flap can be safely used even though the skin may not be as pliable as normal skin.Copyright © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.
