What is a basisesamoid nerve block for horses?
Most clinicians proceed to a basisesamoid nerve block if the horse’s lameness is not reduced with a PDN block. With this regional nerve block, the palmar nerves are anesthetized at the level of the base of the proximal sesamoid bones, before the nerve branches into the dorsal and palmar digital nerves.
How does a nerve block work on a horse?
Diagnosing Equine Lameness – Nerve Block Basics. Nerve blocks work by effectively interrupting the transmission of the pain signal from the affected area to the brain. When the painful area is below the region that is anesthetized, the horse no longer perceives the pain, and its gait will temporarily improve.
