Reconstruction of burn contractures with free anterolateral thigh flap in various anatomic sites.

Abstract

Burn contractures that cause a restriction in extremity movements have to be reconstructed. Free microvascular flaps are generally needed in cases of severe contractures. The ideal free flap for severe contracture defects has to have a large skin island without bulk and a long pedicle for preventing recurrence and tension-free adaptation. Anterolateral thigh flap (ALT flap) that meets these features has widely been used for several indications in reconstructive surgery. Usage of ALT flap in burn contracture was described for burn and axillary contractures in literature. In this study, the usage of free ALT flaps in various anatomic contracture sites was reported. Fifteen free ALT flaps were performed in 14 (12 male, two female) patients with a mean age of 36.6. Burn contracture defects in neck, axilla, popliteal, cubital region, plantar foot and hand were reconstructed with ALT flap. No total flap loss was encountered. Distal flap necrosis was seen in one case. All patients had significant improvement in a range of motions. Recurrence in contracture was seen in one patient with hand flexor contracture due to lack of physical treatment. ALT flap can safely be used in various anatomic contracture sites. Suprafascial elevation of the flap can be preferred for better adaptation in the neck, hand and foot and prevention of bulky appearance.
