Active range of motion outcomes after reconstruction of burned wrist and hand deformities.

This works aim is to evaluate the efficacy of skin grafts and flaps in reconstruction of post-burn hand and wrist deformities. A prospective study of 57 burn contractures of the wrist and dorsum of the hand was performed. Flaps were used only if there was a non-vascularized structure after contracture release, otherwise a skin graft was used. Active range of motion (ROM) was used to assess hand function. The extension deformity cohort uniformly underwent skin graft following contracture release with a mean improvement of 71 degrees (p<0.0001). The flexion deformity cohort was treated with either skin grafts (8 patients) or flaps (9 patients) with a mean improvement of 44 degrees (p<0.0001). Skin grafts suffice for dorsal hand contractures to restore functional wrist ROM. For flexion contractures, flaps were more likely for contractures >6 months. Early release of burn contracture is advisable to avoid deep structure contracture.

The reverse sural flap: modifications to improve efficacy in foot and ankle reconstruction.

The aim of this work is to evaluate the efficacy of the reverse sural flap in covering defects in the foot and ankle region when certain technical modifications are employed. We provide a retrospective review of 32 consecutive reverse sural flaps for foot and ankle defects, and compare the technique and results with other reports. There were 23 fasciocutaneous flaps, 7 fascial flaps, and 2 tissue-expanded flaps. Four flaps (12.5%) suffered significant flap loss, and 4 patients had delayed healing.Several modifications are suggested to increase the versatility of the sural flap in covering foot and ankle defects, including preserving the mesentery connecting the sural nerve to the deep fascia, inclusion of skin of the upper third of the leg, limiting pedicle width to 2 cm with preservation of a tongue-like skin process all along its length, and generous release of the fascia over the peroneal compartment. In addition, we describe the use of tissue expanded sural flaps.

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.

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.
