Abstract / Summary
Reconstructing fingertip injuries with bone exposure requires restoring sensation, function, and contour. This study evaluated a single-stage technique combining artificial dermis with a local volar fascial flap for Allen type II–III defects. We retrospectively reviewed 35 patients (45 fingers) treated between May 2024 and May 2025. All underwent meticulous debridement, elevation of a volar fascial flap for bone coverage, and application of Lando® artificial dermis. Primary outcomes were healing time, 3-month Vancouver Scar Scale (VSS) score, and Fingertip Injury Outcome Score (FIOS). Subgroup analyses were performed using Mann–Whitney U tests with False Discovery Rate correction. All wounds healed completely within a mean of 31.60 ± 4.07 days. Scar quality was favorable with a mean 3-month VSS of 2.02 ± 0.78. According to FIOS, 91.1% of fingers attained good or excellent early functional outcomes at 3‑months follow-up. Complications included one wound infection and two hook nail deformities. Subgroup analyses revealed no statistically significant differences in outcomes across Allen type, age, defect size, or injury mechanism subgroups after correction. The single-stage integration of artificial dermis and a volar fascial flap provides satisfactory therapeutic outcomes for fingertip defects with bone exposure. This technique features technical simplicity, good early functional and aesthetic restoration, and minimal complications. It achieves complete wound coverage in a single procedure, representing an ideal approach for emergency management of fingertip injuries. Level 4, according to the Oxford 2011 Levels of Evidence.
