Summary

Injection of local anaesthetic solution around the palmar nerves at the base of the proximal sesamoid bones is typically considered to desensitise structures distal to this location. There has been recent research investigating the potential for proximal diffusion of local anaesthetic solution resulting in desensitisation of structures other than those intended. This case series describes lame horses that respond to this block but have pathology within the suspensory ligament branches, the distal aspect of the third metacarpal bone and/or the proximal sesamoid bones as seen with high field magnetic resonance imaging.
