This is a review of what kind of wounds occur in the horse, what needs to be done about them and how to make them heal with the best possible outcomes. In a nutshell, there are partial skin thickness wounds and full thickness wounds. Partial skin thickness wounds can be bloody and will heal without much attention needed for their good outcomes.
Full thickness wounds can be divided into fresh and chronic. All can be declared infected with possibly the surgical incision made in a controlled environment. How they heal can be divided into primary intention (suturing) and secondary intention (not sutured). The key to success is to first eliminate infections.
I discuss all these factors based on attending the virtual AAEP meeting of 2021 where there was a multi-part series of presentations that discuss biofilms, debridement and grafting. All of this needs to be understood by the horse owner as quick action in fresh wounds or appropriate action in wounds discovered a day or more later will determine how successful the outcome will be.
