Background and objective.

Scar contractures in the hand are a sequela of burns that can lead to functional impairment. The perforator flap from the digital artery, taken from the lateral aspect of the fingers, represents an excellent therapeutic option for managing these injuries. We present our experience with this surgical technique and our morphological and functional results.

Methods.

We present our experience with 14 flaps in 7 patients affected by web contractures in the hand. These flaps, based on perforators from the digital artery, use the adjacent lateral aspect of the proximal phalanx as the donor site. The donor area was covered with full-thickness skin grafts. Patients underwent early rehabilitation, pressure therapy, and nighttime splinting.

Results.

The survival of the flaps was successful in all 14 cases. One case experienced graft necrosis in the donor site of the flap, which resolved with conservative treatment. Commissural contractures were resolved in 85.7% of the cases (13 out of 14 cases). The mean follow-up period was 27.3 months (range 12-45 months). In 1 case, partial recurrence occurred at 10 months and it was successfully managed with Z-plasty. Patients reported subjective improvement in hand functionality and aesthetics. The interdigital space angle, measured in degrees, improved from a mean of 22.5 degrees preoperatively (range 15°-35°) to a mean of 36.8 degrees postoperatively (range 25°-45°).

Conclusions.

In our experience, the perforator flap from the digital artery represents a rapid, straightforward, and effective therapeutic option for treating contractures after burns in the second to fourth interdigital spaces. Adequate postoperative care, rehabilitation, pressure therapy and splinting are essential for optimal outcomes
