ObjectivesTo evaluate the fingertip reconstruction with occlusive dressing and explore the mechanisms and the mediators of this "fingertip regeneration".Patient And MethodsNineteen patients who sustained a fingertip injury were treated with occlusive dressing. Two prospective studies: a clinical analysis of the aesthetics and the functional results, a biologic analysis of the dressings in order to search microorganisms, cytokines, and growth factors.ResultsAmong 15 patients reviewed, the healing was acquired in 2.7 weeks (2.5). The thickness of the fingertip was excellent in 30% and good in 70%. The Weber test was 3.8mm for the fingertip reconstruction against 3mm for the opposite side. The analysis of the dressing exudates brings to light a pullulement of saprophyte bacterium of the skin but also pathologic species, and presence of angiogenic factors (PDGF, VEGF, EGF).ConclusionsThe occlusive dressings remain a reliable and reproducible alternative for treatment of fingertip injuries in zone 1 and 2. This reconstruction seems to depend on bacterium pullulement and cellular growth factors liberation.Copyright © 2010. Published by Elsevier SAS.
