Yes I have heard of it. As LadyJane said, you do need a second opinion from a board certified osteo surgeon.

Elbow Dysplasia unlike Hip Dysplasia, can be a combination of three things of which un-united anconeal process is one.

Also it csn have two or more conditions present at the same time. Surgery success rates varies.

So get as well as you can a best informed and complete diagnosis, along with success rates et al, and then make your decision

I hope your lad is doing well today.
