Your vet may diagnose

Quittor, Infected Collateral Cartilage

Synonyms: Coronary Sinus

Summary

Collateral cartilages are flexible sheets of cartilage that protrude off the back of the wings of the coffin bones within the heel of the foot. In normal horses, these cartilages are paired, firm, rubbery-feeling, flexible ridge visible and palpable in the heel.

Quittor is a condition in which a collateral cartilage (usually in a front hoof) becomes chronically infected. This usually happens secondary to another hoof infection or a wound that involves the cartilage.

Signs are lameness, swelling of the bulbs of heel and coronet, and drainage.

Treatment is often surgical removal of the affected cartilage.
