[Postmortem exsiccation of the fingertips--results of a systematic quantitative and qualitative experimental study].
To date there have been no results published on qualitative and quantitative time-related changes with regard to desiccation of human fingertips post mortem. The fingertips of 52 hands from 36 corpses were qualitatively examined soon after death (2-6 h) to 120 h post mortem. The quantitative investigations were confined to the tips of the middle fingers. The width of three adjoining ridges of the skin was measured in four defined areas of the middle fingertips, and photographs were taken at intervals of 2, 3, 4, 5, 6, 7, 8, 12, 20, 26, 32, 44, 50, 60, 72, 84, 96 and 120 h p.m. Concerning the qualitative test results, four time-related stages were classified macroscopically and by a pocket lens (X25). Desiccation stage IV correlates to the period 72 h after death in bodies found in apartments. Besides the rough, wrinkled, and brown or black surface of the fingertips, microwrinkles of the epidermis occur on the skin ridges, which have so far not been described. The quantitative results did not show any changes in the width of the skin ridges, independent of age, sex, right or left hand.
