Fingertip amputations treated with occlusive dressings

Abstract

The aim of this study was to analyze a series of patients who suffered a distal finger amputation and who were treated with occlusive dressings. A retrospective study was done of 19 patients from a single hospital. At the review, an independent examiner evaluated the time required for wound healing, the number of occlusive dressings used, fingertip trophic skin changes, epicritic sensitivity using the Weber two-point discrimination (2PD) test, sensitivity based on the monofilament test, complications, the presence of dysesthesia or cold intolerance, and the QuickDASH score. The mean follow-up was 12.6 months (6-25). A mean of 3.2 occlusive dressings (3-5) were used per patient, and the mean healing time was 4.3 weeks (4-5). The skin texture, fingertips and nail bed were good or excellent in 18 cases. The 2PD test was good or normal in 16 cases. Eighteen patients were satisfied or very satisfied with the outcome. The mean QuickDASH score was 5.53 (0-20.45). In the literature, the recovery of tactile sensation is good after use of occlusive dressings (2PD of 2.5 to 4.0mm). The mean sensitivity reported in various studies is better than that observed after use of a skin flap. While the sample size in our study was small, the functional outcome and appearance were good. Thus we prefer using occlusive dressings in Zone 1 and 2 fingertip amputations, and flaps in zones 3 and 4 to ensure better fingertip viability and sensation.
