Abstract
PURPOSE: This study aimed to compare and analyze the outcomes of finger reconstruction using free distal ulnar artery perforator (FDUAP) and reverse dorsal homodigital island (RDHI) flaps. METHODS: The study included 27 patients with finger pulp defects that were reconstructed using FDUAP or RDHI flaps. Standardized assessment of outcomes included objective sensory recovery, duration of operation, range of motion in the repaired fingers, pain at the reconstructed finger pulps and donor sites, and recovery time before returning to work. Subjective assessment of outcomes included the cold intolerance, aesthetic appearance, and functional recovery. RESULTS: All flaps in the series showed complete survival. The average surgical time for the RDHI flaps was significantly smaller than that for the FDUAP flaps. Sensory recovery was significantly better with FDUAP flaps than with RAHI flaps. No significant differences were detected between the 2 procedures regarding range of motion, cold intolerance, or pain of the injured finger pulps and donor sites. The outcomes of aesthetic result and functional recovery satisfied all patients. Optimal cosmetic satisfaction was obtained in the FDUAP flap group. CONCLUSIONS: Although both types of flaps offer a satisfactory approach for finger reconstruction with small-to-medium defects, FDUAP flaps are more suitable for such operations because of the better sensory reconstruction and aesthetic results.
