Three-dimensional finite element analysis computer model of skin incision: application of sutures and −80 mm Hg NPWT. (a) Incision model from Figure 1 with sutures applied. Pattern of forces around skin incision in millimeters of tissue deformation from its starting position due to the inherent lateral tensions in the tissue when the incision is made (blue is small; red is larger). The plane of the section is across the incision. (b) Close-up from (a). (c) Incision with NPWT dressing applied (−80 mm Hg). (d) Close-up from (c). NPWT indicates negative pressure wound therapy.
