Question about angular limb deformity and UAP (ununited anconeal process)

Ok so my wife and I recently adopted a Basset/ poodle mix named moose. I posted a picture of him yesterday. We got him at 4 months and is now 8 months old. About a month ago he started limping on one of his front legs. We had X-rays done and they diagnosed him with both of these conditions. Basically part of his elbow didn’t fuse correctly when he was growing so now he has a piece of the joint that is not connected and the same leg also bows outward. We brought him to an orthopedic surgeon this past Monday. They want to do a surgery to fix both conditions as one affects the other. They want to do the osteotomy to help correct the bow and take pressure off elbow joint and put a screw in the piece that didn’t fuse correctly while he is still young in hopes to have it fuse. We are most likely going to have the surgery done bc we want what’s best for our little Moose and don’t want him to be in pain.

Has anyone with a Basset had any of these issues before, has anyone had any such surgeries and if so what was the outcome and how has it been since?

Thank you for taking the time to read this as it’s quite long lol.
