Abstract
Background: Homodigital adipofascial flap is a well‐established method for treating a distal fingertip defect; nonetheless, its use has some limitations. Reconstruction of fingertip injuries, with radial or ulnar tissue loss, may lead to some difficulties in providing an adequate bone coverage. The standard bipedicled technique did not allow the flap to cover the bone exposure without excessive tension. In our series, the reverse adipofascial flap had a single pedicle. The modified technique, because of its improved degree of rotation, granted the flap to reach either radial or ulnar tissue losses.Patients and Methods: We treated 15 fingertip amputations distal to the lunula (9 Allen's type II and 6 type III), the mean size of defects was 2.7 cm2 (range, 1.8–3.2 cm2), the mean age of patients was 44 years (range, 22–63 years). Quick Disabilities of the Arm, Shoulder, and Hand score and Visual Analogue Scale were evaluated along with a 2‐point discrimination test; the aesthetic satisfaction of the patients was estimated subjectively using a 5‐point Likert scale.Results: Mean flap size was 3.6 cm2 (range, 2.5–4.2 cm2), primary flap survival was observed in 14 out of 15 cases, partial flap necrosis was observed in 1 case, the nail grew in all fingers in about 6 months. Mean proximal and distal interphalangeal joint motion was 89° (range, 80°–100°) and 71° (range, 65°–80°), respectively. No complications were observed at the donor site. The median static 2‐point discrimination was 4.5 mm (range, 3–8 mm), the mean quick DASH score was 2.6 (range, 0–9.1). All patients returned to work within a mean of 4.4 weeks (range, 4–5 weeks). The follow‐up was 12 months.Conclusions: Single pedicle reverse adipofascial flap is an effective technique. This modified procedure allows a wider degree of flap rotation; it represents the ultimate arrow in our bow to address some particular defect geometry.
