Review of skin grafting in equine wounds: indications and techniques.

Skin grafting is a simple technique that can be performed by equine practitioners to improve cosmetic outcomes in wounds with large skin defects that would not heal functionally or cosmetically with standard wound therapy interventions. Successful skin grafting is not difficult but relies upon appropriate preparation of the wound bed and effective immobilisation of the grafted area after skin graft placement. Prior to grafting, the wound bed should be treated with a moist wound healing dressing to prepare the granulation tissue bed to receive the graft. For best results, skin grafts should be placed in wounds free of infection with healthy granulation tissue, and motion should be reduced in the graft region in the early postoperative period. When successful, skin grafts cover granulation tissue and encourage wound contraction and epithelialisation while decreasing exuberant granulation tissue resulting in a more cosmetic result. This review will advance practitioners' understanding of skin grafting in horses, including graft classification and techniques, donor site selection, recipient site preparation, postoperative management strategies to optimise graft retention and ongoing research in this field.
