Distribution of radiodense contrast medium after perineural injection of the palmar and palmar metacarpal nerves (low 4‐point nerve block): An in vivo and ex vivo study in horses

Abstract: Proximal diffusion of local anaesthetic solution after a low 4-point nerve block is unlikely to be responsible for decreasing lameness caused by pain in the proximal Mc region. The DFTS may be penetrated inadvertently when performing a low 4-point nerve block.

“…Conversely, proximal diffusion of local anaesthetic solution following ‘low 4‐point’ nerve block is not thought to be responsible for decreasing lameness caused by pain in the proximal metacarpal region (Nagy et al . ). Significant proximal diffusion of local analgesic did occur with time following low 4‐point nerve block in 40 limbs as detected by presence of contrast medium on radiographs, but never progressed proximal to the mid‐metacarpal region (Nagy et al .…”

“…Significant proximal diffusion of local analgesic did occur with time following low 4‐point nerve block in 40 limbs as detected by presence of contrast medium on radiographs, but never progressed proximal to the mid‐metacarpal region (Nagy et al . ). These results suggest that ‘low 4‐point’ or ‘low 6‐point’ nerve block should be performed prior to local analgesia of the proximal metacarpus or metatarsus to improve the specificity of results with diagnostic analgesia (Hinnigan et al .…”

“…Inadvertent administration of local anaesthetic solution into the digital flexor tendon sheath may occur when administering a palmar or plantar nerve block and local anaesthetic solution may be inadvertently deposited in the proximal palmar/plantar pouch of the metacarpo/metatarsophalangeal joint when administering palmar metacarpal/plantar metatarsal nerve blocks (Nagy et al . ; Seabaugh et al . ).…”
