Nerve Blocks

Question 1

Where would you target the common peroneal/fibular nerve in the horse?
What innervation will a horse lose if this nerve is targeted
What will happen functionally?

Answer 1

Targeted as it passes superficially across the lateral aspect of the stifle

Loss of motor to the muscles of the craniolateral crus and loss of sensory information from the dorsal hoof

Will cause a horse to knuckle at the fetlock joint and drag the hoof

Question 2

Where can the tibial and deep and superficial peroneal/ fibular nerves be targeted? What will happen?

Answer 2

just proximal to the tarsus

desensitize the entire distal pelvic limb

Question 3

Which nerves are targeted with a high plantar nerve block (high six point block)? This will provide complete analgesia to what?

Answer 3

targets the medial and lateral plantar nerves
medial and lateral plantar metatarsal nerves
medial and lateral dorsal metatarsal nerves

complete analgesia to the
structures in the metatarsal region and distally

Question 4

Blocking the deep branch of the lateral plantar nerve as it branches just distal to the tarsometatarsal joint is helpful in what?

Answer 4

Diagnosing proximal suspensory desmitis

Question 5

What do the medial and lateral dorsal metatarsal nerves supply?

Answer 5

Most of the fetlock joint capsule

Question 6

The\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ nerves (from the \_\_\_\_\_\_\_\_\_ nerve) supply only a limited area on the plantar
aspect of the fetlock, including the plantar pouch of this joint.

Answer 6

plantar metatarsal nerves

tibial nerve

Question 7

What structures do the dorsal digital nerves supply?

Answer 7

dorsal aspect of the digit and hoof including the:

dorsal pouches of the pastern and coffin joints
dorsal pastern and fetlock joints
dorsal part of the coronary and laminar corium

Question 8

What supplies the plantar aspect of the digit and the hoof?

Answer 8

plantar digital nerves
