Surgical Wound Closure Techniques
The healing of cutaneous wounds after surgery is the result of a cascade of complex biochemical events that can be categorized into four overlapping phases: haemostasis, inflammation, proliferation, and remodelling. All these phases of wound healing are influenced by both intrinsic and extrinsic (inside and outside) mechanical forces which effect the tension in the skin. Evidence shows that extracellular matrix remodelling can be upset by these forces. For example, wounds over or near joints may be more likely to develop hypertrophic scars because of joint movements causing repeated tension on the wound, leading to abnormal scarring.
