Abstract: | The aim of this paper has been to check the diagnostic ability of Scanning Electron Microscopy (S.E.M.) to determine wound direction. We have studied incised wound margins caused by steel blades in human skin samples from cadavers by S.E.M. It was found that a lateral accessory tail existed in 65% of the entrance edges. This finding was recorded in all the cases when wound direction was perpendicular to Lancer's lines of the skin area in which the wound was located. No similar finding in the exit tails was noticed. The depth and length of the wound margins was less accurate an index of the wound direction than a lateral accessory tail. We think that this finding could be useful in determining the entrance margin in incised wounds. |
