Equine wound care update highlights stage-based topical choices: full analysis

VERSION 2 — FULL ANALYSIS

A new VETgirl educational post on topical therapies for wound healing in horses is putting a spotlight back on one of equine practice’s most persistent challenges: choosing the right local treatment for a wound that may look straightforward at the surface, but behave very differently depending on where it sits, how contaminated it is, and what structures lie beneath. The article, featuring Dr. Holly Roessner, reviews topical options for equine wounds and ties them to the normal phases of healing, a framework that remains central to wound decision-making in horses. (vettimes.co.uk)

That focus lands in a clinical area where the basics still matter. Equine wounds are notoriously variable, and the literature and specialist guidance consistently note that distal limb wounds heal more slowly than wounds on the trunk or upper limb. The reasons are familiar to veterinarians: limited soft-tissue coverage, motion over joints, contamination, and a tendency toward exuberant granulation tissue. The American College of Veterinary Surgeons notes that wounds below the carpus or hock, and wounds over joints, are especially prone to proud flesh and prolonged healing. Vet Times similarly frames wound management around careful assessment, staging of healing, and creating an environment that lets the process move forward rather than stall. (acvs.org)

The practical details from equine wound experts support a more tailored, less reflexive use of topicals. Reporting from the 2021 AAEP Convention, EquiManagement summarized Dr. Dean Hendrickson’s discussion of advanced wound dressings, including honey for antibacterial and debriding support, calcium alginate for moderate to heavily exudative wounds, hydrogels for dry wounds or burns, semi-occlusive foam dressings to support epithelialization, and silicone dressings for selected heel bulb injuries and recurrent exuberant granulation tissue. Those recommendations underscore a key point: the “best” topical is often less about brand preference and more about matching the product to the wound bed and phase of repair. (equimanagement.com)

There’s also a cautionary thread running through the expert commentary. In coverage from The Horse, Hendrickson argues that proud flesh is often linked to infection and poor dressing technique, and says inappropriate antiseptic use can be particularly damaging to healing tissue. That’s a useful counterweight to the still-common tendency to reach for harsh topical antiseptics in the field. The broader message from both specialist and continuing-education sources is that moisture balance, atraumatic bandage changes, and control of bioburden matter more than simply applying a stronger product.

The puncture-wound angle adds another layer for practitioners. Educational material tied to AAEP programming identifies Dr. Jaret Pullen as an equine podiatry-focused veterinarian and farrier, and newer reporting from EquiManagement makes the urgency especially clear: solar punctures are among the hoof emergencies that should not “wait until morning.” Pullen’s field advice starts before the veterinarian arrives—owners should be told to leave any foreign object in place and protect the foot temporarily with whatever offloading method is available, such as a hoof boot with a central cutout, a duct-tape roll, foam, or a wooden “donut,” to reduce contamination and pressure on the site.

Once on site, the priority is defining the tract and its relationship to synovial structures, not simply cleaning the surface and applying a topical. Pullen recommends radiographs if the nail or foreign body is still present, and says stallside CT can be especially useful when available because it provides the oblique detail needed to map the injury. If the object has already been removed, the challenge becomes finding a tract that can disappear quickly in the hoof capsule. He advises sharp hoof knives to reopen and identify the path, followed by irrigation with a gavage needle, teat cannula, or catheter. If there is any concern that the tract approaches a synovial structure, he favors dilute 1% povidone-iodine over chlorhexidine because of the latter’s greater tissue risk in that setting. Depending on the anatomy, the next diagnostic step may be a fistulagram, arthrogram, or bursagram; if already entering a synovial structure, he notes that intra-synovial amikacin may be added. A sterile flexible blunt probe and follow-up radiographs can then help define depth and direction. These details sharpen the article’s broader point: in hoof punctures, topical therapy is secondary to anatomy, imaging, and early synovial decision-making. (equimanagement.com)

Pullen’s surgical planning advice also fits the larger wound-management theme of matching treatment to tissue and location. He recommends preparing the foot by trimming, scuffing or rasping the hoof wall to remove the soiled outer layer, and in some cases placing a shoe with impression material before surgery so a hospital plate can be added afterward. He also urges a funnel-shaped surgical approach, widening the distal opening and tapering into the lesion to encourage drainage and access. For clinicians, that is a reminder that successful management of hoof punctures often depends less on what is put on the wound than on whether the tract is adequately identified, opened, imaged, and, when needed, surgically addressed.

Why it matters: For veterinary professionals, this is a reminder that topical therapy in horses sits at the intersection of wound biology, bandaging technique, imaging, and antimicrobial stewardship. Education pieces like VETgirl’s are valuable because they translate a crowded product landscape into a staged, problem-oriented approach. In practice, that means reserving topical antimicrobials for situations where they’re likely to help, avoiding agents that impair viable tissue, and recognizing early when a “routine” wound is actually a referral-level limb, joint, or hoof case. It also means clear communication with pet parents, who may expect a cream or spray to solve the problem when prognosis is really being driven by anatomy, contamination, aftercare, and, in the case of foot punctures, whether synovial sepsis has been ruled out quickly enough.

What to watch: The next step for the field is better comparative evidence. Advanced dressings, biologic materials such as amnion-derived products, and combination antimicrobial dressings are all attracting attention, but clinicians still need stronger head-to-head data on healing time, complication rates, proud flesh prevention, and when local treatment can reduce, rather than add to, systemic antimicrobial use. In parallel, equine practitioners will be watching how protocols for hoof punctures evolve as more referral centers use stallside CT and more continuing education emphasizes early tract preservation, contrast studies, and targeted surgical debridement. Until then, expect equine wound management to remain less about a breakthrough product and more about disciplined case assessment and product selection. (equimanagement.com)
