Sand Cracks in Horses

Sand cracks are vertical cracks that develop in a horse’s hoof. The begin in the wall of the hoof, starting at either the ground level and extending upwards or at the coronary band and grow downwards towards the bearing surface of the hoof wall. A crack that grows downwards is a very serious ailment and can lead to lameness in the horse.

Causes of Sand Cracks

Damage to the top of the hoof, where the horn has been produced, is a common cause of sand cracks. Other causes include incorrect trimming of the feet as well as poor conformation from birth. An unbalanced or overgrown foot can cause a crack that extends from the ground surface upwards.

How They Form

Fissures, set on by a defect in the coronary band, develop into a wound at that point. The quality of the hoof at this site is very poor. When a fissure grows down the hoof a vertical crack is formed. A damaged coronary band results in a permanent sand crack. Horn cells that produce more horn fail to do so to cover up the crack if they are also damaged.

Treatment

Infected cracks must be trimmed out and all evidence of the infection removed. Both local and systemic antibiotic treatment along with a daily dressing will be necessary. A synthetic resin can be used to fill in the trimmed-out crack using staples or wire lacing.
