What is it about?

Edge Trenching is a wound remodeling technique allowing to merge vertical wound edges with the tissue in the wound base. It is often used when the wound edges are vertical, and it is not possible or desirable to debride them at 45 degrees.

Why is it important?

Vertical wound edges are not conducive to wound healing and often cause wounds to stall. When tissue in the wound base does not merge with the wound walls, this wound remodeling technique can help merge similar tissues.


This technique is akin to fruit tree grafting when cutting a tree stem, and a branch allows them to grow together. The Edge Trenching technique is one of two techniques used to manage unfavorable wound edges. Our Soap Scrap technique can be used to manage wounds with undermined edges and pockets.
