Question of the Day

With peroneal paralysis, see knuckling at the fetlock, with dorsal surface of hind foot scraping on the ground.

Damage to the ischiatic nerve or the obturator nerve is seen most often in post-partum cows (and sometimes horses). It is caused by compression of the obturator nerve against the bony pelvic canal as a calf passes through.

Damage to the saphenous nerve would inhibit sensory perception on the medial hind limb and motor innervation to the sartorius muscle (but probably would not cause knuckling).

Radial nerve paralysis is in the forelimb. High radial paralysis would be non-weight bearing. A low radial paralysis would knuckle.
