title: Use of an adipofascial flap based on the proximal perforators of the ulnar artery to correct contracture of elbow burn scars: an anatomic and clinical approach.
abstract: Different techniques can be used to repair contracture of burn scars on the elbow, including local or distant pedicle flaps, muscle or myocutaneous flaps, free flaps, and tissue expanders. Among these, a pedicled adipofascial flap based on the most proximal two to four perforators of the ulnar artery (located 1 to 5 cm from the origin of the artery) can be anastomosed to form a sort of axially patterned blood supply within the fascia and subcutaneous fat. Therefore, no major vessel in the forearm need ever be severed. In addition, use of this type of flap preserves muscle function. The pedicled adipofascial flap described in this article allows for early rehabilitation because the flap is thin and pliable. Additional advantages are the easy and quick dissection and completion of the procedure in one stage. A detailed anatomic dissection of the flap was performed on 16 upper extremities from fresh cadavers; an injection study was also performed to determine the location and dimensions of the pedicle flap and its area of reach around the elbow. In the past 3 years, 14 flaps were used in 13 patients to repair elbow defects after release of burn scar contractures. Flap dimensions ranged from 4 x 7 cm to 6 x 14 cm (mean flap size, 74 cm). The results were very satisfactory.
