Abstract
PURPOSE: The homodigital dorsolateral flap (HDF) was described to treat various types of pulp and fingertip defects. The aim of this study was to analyze the intermediate-term function after fingertip reconstruction with HDF and compare these results with the cross-finger flap. METHODS: We analyzed a retrospective cohort of 25 patients. The HDF group consisted of 16 patients (18 fingertip defects) with a mean age of 44 years (range, 16-63 y). The cross-finger flap group consisted of 9 patients (10 fingertip defects) with a mean age of 33 years (range, 16-47 y). The average follow-up time was 12 months (range, 6-36 mo). RESULTS: Patients with homodigital reconstruction demonstrated better sensibility in terms of mean static 2-point discrimination. Two-point discrimination was also better when the flap was advanced compared with when the flap was rotated. Mean distal interphalangeal joint range of motion for the HDF group was significantly better compared with the cross-finger flap group. Proximal interphalangeal joint range of motion was significantly better in the HDF group. CONCLUSIONS: The HDF for reconstruction of pulp defects is a reliable option for 1-stage reconstruction. Related complications are minimal, and the intermediate-term functional results are better compared with cross-finger flaps. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
