Some of the consequences of neurectomy have been incidentally alluded to: gelatinoid degeneration of tendons, sloughing of the hoof by undiscovered suppuration arising from pricks, wounds, corns, etc. When the operation has been resorted to for navicular trouble, the diseased bone will sometimes fracture or the flexor tendon passing under it becomes excoriated, its fibres soften, and rupture under the weight imposed upon them; the toe turns up, and the hindmost portion of the heel comes to the ground. A swelling now appears round the coronet, a bulging is seen in the hollow of the heel, and ultimately the hoof sloughs away and the end has been reached.
