The surgery involves removing both the lateral and medial palmar digital nerves on the back of the pastern.
What are the risks of nerving a horse?
Complications of this kind of neurectomy can include formation of a painful neuroma, or ball of nerves, at the surgery site, sloughing of the foot, luxation of the coffin joint and rupture of the deep digital flexor tendon.

Navicular syndrome is a chronic degenerative condition that can cause lameness in the front legs. It is most commonly seen in competition horses and quarter horses. It may be caused by repetitive mechanical stress on the navicular bone, resulting in degeneration of tissues and ligaments in the heel.
In many cases therapeutic shoeing may help those horses diagnosed with navicular syndrome. The egg-bar shoe has long since been the choice of many veterinarians to apply in cases of palmar heel pain. Unfortunately, one shoeing application does not work for all navicular syndrome cases.
How much does a horse nerve block cost?
So the cost depends on the location of the problem, but the nerve blocks per leg can vary from $75 per block which can go up to $500 per limb.
