Do not pull the nail out unless you think further trauma will be caused by leaving it in prior to receiving veterinary attention. It is helpful to leave the object in place so that the direction and depth of penetration can be determined.
There are a number of structures within the foot that can be affected by a nail puncture. The caudal half of the foot has some of the most vulnerable structures, such as the navicular bursa, which can become severely infected if they are injured by a foreign body.
A puncture is evaluated radiographically and onCE the severity of the lesion can be fully assessed , a treatment plan can begin. Some horses may only require antibiotics while others may require surgical intervention. Depending on the nature of the injury the horse may require a special shoe.
