Toe Extension

1. A heart bar shoe with a toe extension has been applied to this front foot due to a tendon contraction resulting in excess heel growth and a rotation of the pedal bone.

3.This picture shows the right fore, which did not need an extension but was shod with a heart bar shoe to support the hoof capsule after the dorsal (front) wall had been reduced and the hoof trimmed to the correct hoof pastern axis.
Note the half moon shape at the bottom of the wall. This is where the lamininal wall has stretched and separated. This is due to a mechanical laminitis, the horse was not equally weight bearing on both feet, it favoured its left fore so the right fore was under incresed load even standing still.

Foal toe extension

Here is a foal extension using a steel shoe glued to the hoof using resin. This foal had to have surgery to cut its check ligament and a substantial extension was fitted due to the fact the horse had not been reffered early enough.
Under more normal circumstances the foal would have been treated soon after birth if this was a congenital problem or at only a few weeks old if it had acquired the upright hoof due the the dorsal wall cracking off or maybe due to ground conditions.
In these cases a hard resin would be applied to the dorsal (front) wall which would be then assesed after 7-14 days and the extension would be then maybe re-applied, reduced or taken off.

I have just done an interesting "rescue-job" on the leg of a weanling colt sent up from a colleague in Cornwall. Whether or not a direct trauma had also been involved, the foal essentially suffered from a developmental problem which had resulted in the cartilage in one hock joint becoming detached and the joint, therefore, severely distended and resulting in a lame foal. To worsen matters, the growth plate immediately above the hock had also run into problems and produced more bone on the inside of the limb, so the foal had a 19 degree angle of its lower limb.

Two surgical procedures were required, firstly removal of an approximately 2x4 cm semi-detached cartilage-flap from the joint, secondly a procedure on the slow growing side of the growth plate to encourage it to catch up. Finally, my trusted farrier, Robin Compton applied an acrylic hoof extension to the inside of the limb to correct the loading of the leg. The foal has now been discharged for emergency weaning (not a day too early) in order that he can get removed from the 24/7 milkbar he has been frequenting and get onto a diet we can have some say in. He will be box rested with walking only for 2-3 months before we see how successful we have been in straightening the leg. The long term prognosis remains reasonably encouraging only because of his young age
