Skin grafting with the modified Meek technique in the standing horse using full thickness skin: Evaluation of acceptance, wound contraction and wound closure in chronic wounds

Abstract Background The modified Meek technique is not commonly used in equine wound management, despite the consistent reliable and superior results compared with other grafting techniques. Major drawbacks are the need for specialised, expensive equipment and general anaesthesia. Objectives To describe adjustments of the modified Meek technique enabling use in the standing horse without the need for the full equipment. This implied the use of full‐thickness skin grafts manually harvested from the pectoral area and manually cut into micrografts. Graft acceptance; healing progress; and final functional and cosmetic result were outcome parameters. Study design Descriptive case series. Methods Eight horses with traumatic wounds at the dorsal side of the carpus or tarsus, healing by second intention, were treated. Original wound areas and areas of graft acceptance and rejection were determined from post‐processing of digital photographs and percentage acceptance, wound contraction and epithelialisation were calculated. Results The initial mean wound area was 55.4 cm 2 . Graft acceptance was 95.3 ± 2.5%. Wound closure was due to 46.0 ± 25.6% wound contraction and 54.0 ± 25.6% epithelialisation and resulted in 96.8 ± 1.9% reduction of the initial wound area 28.0 ± 8.5 days after grafting. The scar was flat, flexible and functional, usually with thin and regular hair growth. The adapted procedure was fast and efficient, with a learning curve for the increased manual work. Main limitations Small study population. Conclusions This adapted modified Meek technique can successfully be performed in the standing horse and obviates the need for the full expensive equipment and general anaesthesia. The acceptance of the full‐thickness grafts is excellent resulting in fast and satisfactory healing.
