Quiltor is a somewhat archaic term used to describe the result of an injury to the leg, usually an abscess seen on the coronary band above the hoof of a horse or other equine. It occurs when an injury allows foreign matter to get into the leg and then collect beneath the hoof and an infection sets in. In some cases, to remove this matter, it may be necessary to cut away parts of the hoof. Abscesses may also form inside the hoof capsule itself from improper shoeing and trimming of the hoof, from laminitis, or from injury to the sole of the hoof, but the horse will be significantly lame for a longer period of time if the infection has to migrate up to the coronary band rather than down. Treatment of hoof and coronary band abscesses today usually incorporates use of antibiotics, sometimes combined with poulticing.
The term was common in the 19th century, but is not commonly used today. In the 1890 International Cyclopedia, it was described as "a fistulous wound about the top of a horse's foot, and results from treads, pricks, or neglected corns, which lead to the formation of matter underneath the hoof. Any dead horn, matter, or other cause of irritation must be sought for by cutting away the hoof. A free opening must be provided for the egress of any pent-up matter. Poulticing for a few days is often useful; while healing may afterward be expedited by the injection of any mild astringent lotion."
