Last month I did a quick little tutorial on how to do a basic fix on a broken leg using wire. This month I find myself fixing another leg, this time more complicated because it’s broken right below a joint.
This fix uses a similar technique, but with a bit of a tweak to make it more stable.

The sad (and blurry, sorry) victim:
This break was half on purpose and half not- I was intentionally repositioning the leg, but failed to heat it enough before bending and it snapped. Oops.
Because the break is right below the bent hock, I need to use a wire join that is also bent to follow the shape of the leg so that it actually stabilizes the break.
The first step in the fix is simply to embed a piece of wire into the straighter side of the break, in this case the cannon bone (just like in steps 1-2 of the first tutorial). Once the wire is fully fixed in that side and the glue is dry, gently bend the wire to match the shape of the full leg (see below).
Since my wire joiner has a bend, the hole its going to fit into, in the upper part of the break, needs to match that bent shape. I used my carbide scraper to dig out a trench in the front of the bent hock. You could certainly use a dremel, but it’s not necessary.
Here I’ve dug my trench into the hock and fixed the wire, now bent, into the model’s cannon bone.
I keep scraping until the wire nestles fully into the trench and the leg lines up properly.
The wire nestled in its new home
Here I’ve got the leg just about where I want it.
As you can see above, I’ll need to do some resculpting (including removal) on that hock joint to make it anatomically correct. The important thing here is to get the bottom part of the leg securely where I want it to be on the finished custom, and then I can worry about the details.
Once the wire sits fully in the trench and you have the leg positioned how you want it, just fix the wire into the trench using superglue and baking soda. It sometimes helps at this stage to have an extra hand, or rest your horse upside down in a cup so you can hold the leg in place while still applying glue.
Once the glue is dry, make the fix even more secure by filling in the surrounding area with your epoxy of choice.
