It is an inside joint replacement. As soon as I get the proper lighting, I will be digitizing the after x-rays. Basically for the Ulnar component it is a bar that is shoved into the existing bone, with the HUmeral component being the same except that is it larger, and has an extra flange that they graft bone to to keep it from freely rotating inside the bone. The two pieces connect together with a Pin and a Poly-Ethylene bushing (the elbow). I have an extra heavy duty pin, bushing, and flange (custom built for me) with two bone graft "Struts" for added stability on the Humeral end piece.
The part that I broke was the stem of the humeral component approx 4 inches up inside the bone.
It's all good. I just have to retire from racing my 4-wheeler and my dirt bike.
