Enthusiasm for these treatments should be tempered by the understanding that treatment of the wound's underlying origin is paramount and that cost and cost-effectiveness should be considered closely.

Wound healing includes 3 overlapping phases: inflammation, tissue formation, and tissue remodeling. This involves a complex, dynamic series of events including clotting, inflammation, granulation tissue formation, epithelialization, neovascularization, collagen synthesis, and wound contraction.1 These events overlap in time, and involve a complex array of cytokines secreted by platelets, macrophages, neutrophils, fibroblasts, and epidermal cells.1
