In this episode of The Hoofcare Companion, host Marc Jerram explores one of the most valuable tools in equine veterinary diagnostics: nerve blocks. From the basics of how they work to their role in pinpointing the source of lameness, this episode takes you step by step through the science, techniques, and practical applications of perineural anaesthesia.
We discuss the different types of nerve blocks from palmar digital to high four-point and highlight how they guide accurate diagnosis, reduce unnecessary imaging, and improve treatment outcomes. Alongside technique and pharmacology, we cover recent innovations, case studies, and even ethical and regulatory considerations in equine sports medicine.
Whether you’re a farrier, veterinarian, or horse owner looking to deepen your understanding of lameness evaluation, this episode provides a clear, practical look at how nerve blocks support better decisions in hoofcare and overall equine health.
