Absolutely!!! Fusing is old style - if the joint hurts, take it out or fuse it, and it stops hurting. Don't bother with the fact that you can't use it any more. I have had 3 local surgeons advise fusing my big toe due to arthritis, bone spurs, etc in that joint. I was already struggling with a joint that didn't bend right and hurt every time I walked.
I found a better sureon "Hell no we don't fuse joints!" She cleaned it out, repaired what she could, and put it back together. That was 4 years ago. I am still walking straight and pain free, and doing the difficult mountain hikes!
Get as many opinions as you need until you find the surgeon that really understands your issue.
