Name That Nerve
A decreased patellar reflex indicates a deficit in this nerve.
What is the femoral nerve?
A cow with shoulder and elbow drop who can’t extend the leg likely injured this nerve proximally.
What is the proximal radial nerve?
A cow can stand and walk once lifted. This is Grade 1 of what?
What is a femoral nerve deficit?
An increased patellar reflex points to a deficit in this large hindlimb nerve.
What is the sciatic nerve?
This nerve deficit causes dropped hock and partial fetlock flexion.
What is the tibial nerve?
A cow with a flexed forelimb digit who can’t extend it likely has this type of radial nerve injury.
What is a distal radial nerve deficit?
A cow that can stand but not walk after being lifted has this grade of femoral nerve injury.
What is Grade 2 femoral nerve deficit?
A hock that bends too far forward postpartum likely means this.
What is gastrocnemius rupture?
A cow can't adduct her hind limbs due to paralysis of this nerve.
What is the obturator nerve?
A cow in lateral recumbency who can’t go sternal likely has this severe lesion.
What is a brachial plexus deficit?
A cow’s legs are in normal position when sitting, but she can’t stand or walk when lifted.
What is Grade 3 femoral nerve deficit?
Splayed legs + iliac bones protruding = likely this pelvic condition.
What is coxofemoral or sacroiliac joint luxation?
This nerve causes knuckling at the fetlock and a “sassy hoof.”
What is the distal sciatic nerve?
You see cranio-medial deviation of the limb and frog-leg posture bilaterally. Localize the lesion.
What is a proximal sciatic deficit?
The cow is in constant frog-leg position. Prognosis?
What is Grade 4 femoral nerve deficit, euthanasia recommended?
A dropped hock with a sassy hoof but preserved proximal limb strength = this lesion.
What is a tibial nerve deficit?
In calving paralysis, this large hindlimb nerve is usually affected.
What is the sciatic nerve?
If a down cow is crawling forward but can’t extend her stifle, it’s likely this specific deficit.
What is a femoral nerve deficit?
A recumbent cow with elevated CK and several days down has this likely outcome.
What is guarded (compartment syndrome)?
In grading non-proximal sciatic deficits, this grade includes loss of skin sensation both dorsally and plantarly.
What is Grade 3 (peroneal and tibial nerve involvement)?
