Pinch Grafting: Tiny Skin, Big Impact on Diabetic Foot Wounds

In this episode Dr. G explains pinch grafting — a simple autologous technique that places tiny pieces of a patient’s own skin onto a prepared wound bed to create epithelial “islands” that promote closure. She covers the history of the Reverden graft, the biology of graft take (plasmatic imbibition, inosculation and neovascularization), and how epidermal islands accelerate re-epithelialization.

The episode emphasizes the critical need for wound-bed preparation, adequate perfusion, infection control, offloading, and systemic optimization in diabetic foot care, compares pinch grafts to split-thickness grafts, and outlines indications, common causes of failure, and the role of grafting in limb salvage.
