Are risks & outcomes worth surgery for ?plri, bone fragment, unknown for clicking 30 times a day post radial head fracture - 8 months ago plus rehab?

Yes: You should have had an MRI by now to look at the details or a ct scan. I think that you need to have it scoped and the ortho surgeon can definitely see what is going on and see what needs to be done next while in the or. A good surgeon will give you a few of the likely possibilities in the office beforehand.

Depend overall healt: It depends on your overall health. It should be a short procedure between 30-45 min and if conservative measures have not helped in over 6 months and it is interfering with quality of life and causing moderate discomfort, it makes sense to proceed with surgery. If you do not have co-morbid issues that can cause problems with surgery (liver issues, poorly controlled htn, diabetes), emphysema ok.
