Equine Ailments - A to Z
Pedal Ostitis - An aseptic inflammatory reaction in the os pedis i.e. bruising. It is one of the most common causes of lameness. The inflammatory reaction may extend to the soft tissue covering the os padis. Normally caused through trauma and concussion it often involves the laminae and the sensitive sole. It is more common in the front feet and there may be a mild degree of laminitis present. The vascular system is involved and there is a degree of congestion, which prolongs the course of the disease and may be responsible for the condition becoming chronic. The inflammatory reaction in the os pedis leads to a general roughening of the pedal bone, the lower border of the bone erodes, loosing its sharp and even appearance. In other areas production of an excess of new bone appear particularly on the sole and under the wings.
Symptoms - the horse will be tender on his feet, over rough ground or gravel he may go very lame. There will be a little heat in the foot and if the sole is tapped lightly flinching will occur. Sometimes there will be evidence of bruising of the sole.
Treatment - The vet will X-ray to confirm the diagnosis. Anti-inflammatory drugs and remedial shoeing can ease the symptoms. Simplest is to turn the horse out on soft land for 6 months to a year with frequent inspections and attention to the feet. Wide webbed protective shoes should be fitted, to relieve pressure on the sole. The farrier may advise that the horse’s heels should be deepened a little and the toe slightly dumped. |
