Description
Summary:Autologous skin grafts are successfully used to close recalcitrant chronic wounds especially at the lower leg. If wound care is done in a dermato-plastic team approach using the “integrated concept,” difficulties associated with harvesting the skin graft as well as the complexities associated with inducing closure at the donor and the recipient site can be minimized. In the context of wound healing, skin transplantation can be regarded as (1) a supportive procedure for epithelialization of the wound surface and (2) mechanical stability of the wound ground. By placing skin grafts on a surface, central parts are covered much faster with keratinocytes. Skin (wound) closure is the ultimate goal, as wound closure means resistance to infection. Depending on the thickness of the skin graft, different amounts of dermis are transplanted with the overlying keratinocytes. The dermal component determines the mechanical (resistance to pressure and shear forces, graft shrinkage), functional (sensibility), and aesthetic properties of the graft. Generally speaking, the thicker the graft the better the mechanical, functional, and aesthetic properties, however, the worse the neo- and revascularization. Skin grafts do depend entirely on the re- and neovascularization coming from the wound bed. If the wound bed is seen as a recipient site for tissue graft, the classification of Lexer ( Die freien Transplantationen. Stuttgart: Enke; 1924) turned out to be of extreme value. Three grades can be distinguished: “good wound conditions,” “moderate wound conditions,” and “insufficient wound conditions.” Given good wound conditions, skin grafting is feasible. Nevertheless, skin closure alone might not be sufficient to fulfill the criteria of successful defect reconstruction. In case of moderate or insufficient wound conditions, wound bed preparation is necessary. If wound bed preparation is successful and good wound conditions can be achieved, skin grafting is possible. If, however, this attempt is unsuccessful and moderate or “inadequate wound conditions” are persisting, other methods of defect reconstruction such as local flap transfer, distant flap transfer, free (microvascular) flaps, and ultimately amputation must be considered.
