Pedal Bone Fracture (PIII fracture)
Pedal Bone fracture (PIII fracture)
A 17 yo Gelding became abruptly lame while trotting on a rocky terrain. He is Bright alert and responsive. Lameness 5\5. Responsive to hoof tester, on the solar surface, especially on the medial side and the toe area. After a mild trim job, in hope of finding an abscess some hemorrhage and bruising was found on the medial side and the toe area of the sole.
We grade lameness from 1-5/5. 1/5 would be a very mild lameness, very hard to recognize. 5/5 is a horse that in not bearing any weight on the leg.
We apply hoof testers on the foot to get an inflicted painful response. A horse that is doing well will not respond at all to the hoof testers if used correctly. when there is a response, we know where to look.
On the x rays a fracture was noted on the medial side going toward the toe area. It is a oblique fracture that does not involve the Coffin joint.
In these fractures we are worried about the involvement of the joint and the age of the horse. There was no involvement of the joint so the chances of recovery are good although the horse is 17-yo and this means that the bones heal slower and weaker than a younger horse.
A bar shoe was placed on the hoof and a cast was applied. Usually ether would do but I thought that the bar shoe was not sufficient, that the clips on the side did not hold the hoof tight enough. The idea is to make sure that there is a minimal amount of movement inside the hoof capsula.
After a two weeks the horse did not show a lot of improvement. After a month the horse improved dramatically and today he is turned out after only two and a half months from the injury.
