A study relating wound tension to scar morphology in the pre-sternal scar using Langers technique

Using the techniques of Karl Langer (1861) a cadaver study has been performed to relate the pattern of skin tension to scar morphology found in the pre-sternal scar. It is demonstrated that hypertrophic scarring occurs in areas of high tension with "pull" in many directions, but that a stretched scar results from increased tension in one axis only.
