I knew I wanted a neurosurgeon so I didn't look at/for any ortho. The PM doc that did my ESI's recommended neurosurgeons over ortho. He said he ususally doesn't stereotype, but feels ortho usually have better bedside manner than the neurosurgeons - but it's what happens in the O.R. that matters. Since you already have an ortho you like, it will probably be a tougher decision for you.
I think any major surgery deserves a second opinion, and many insurances will pay for multiple opinions. Since you are still in the deciding stage, I would get multiple opinions and see who you feel most comfortable with.
I have also asked any nurses or docs who they themeselves would go to. I've even made phone calls to the hospitals or surgery depts. etc. that would go something like "I assume you are not allowed to give referrals or recommendations, but I am new in town and do not want to be "flying blind" so, I would just like to ask who does the most (ie cervical fusion) cases, or ask who most nurses /docs go to." - I expected to have some that wouldn't give me info, but I if you are careful with your wording (like who does the most of these) so not to put them on the spot, sometimes you can get good info.
I also got the opinion of my GYN, the Pediatrician etc. Left message with nurse like "I know it's not Dr. X's dept, but value his/her opinion so would like to know who s/he recommend for such & such."
- - If you see the same name start popping up among all these then that's a very good sign.
Good luck with choosing the right healthcare provider and path to better health.
