title: Treatment of equine leg wounds using skin grafts: Thirty-five cases, 1975-1988.
abstract: A retrospective study was conducted on 35 equine patients with lower leg wounds that were managed utilizing skin graft procedures. Two pinch graft, five punch graft, seven tunnel graft, eight split-thickness mesh graft and thirteen full-thickness mesh expansion graft procedures were performed in the initial treatment. The average wound size was 188 cm(2). Twentyfour cases had pregrafting complications: 10 wounds developed sequestra; three wounds were grossly contaminated and infected; and 11 cases developed granulation tissue complications prior to grafting. Graft failure following the initial procedure was seen in 12 cases and occurred with all techniques except pinch grafting. Graft failure was often attributable to poor quality of granulation tissue as well as anatomic site, especially the dorsal surface of the tarsus. An average of two additional grafting procedures was required to successfully treat initial failures. Pinch grafts took the longest time to epithelialize (70 days), followed by punch grafts (47 days). Both were similar in terms of being the least durable and least cosmetically acceptable of all techniques used. Split-thickness and full-thickness mesh expansion grafts were technically the most difficult, but showed the most rapid epithelialization (28 days), greatest durability, and the best cosmetic appearance. Tunnel grafts provided a practical technique for grafting cases which were either not suited for, or which had failed with, mesh expansion grafts.
