I had to have four cervical vertibrae fused and the first Surgeon I saw was a worthless Woman (she was -no- Lady !) who clearly didn't want to do the job and
LIED TO ME in the first pre op meeting so I called membership services and complained, I got very lucky as they gave me their top cervical Neurosurgeon who fixed me up very well indeed, I have a long metal plate and 8 screws in my neck now yet have manageable pain levels and can even now turn my head enough to safely look before lane changes etc.....
He told me after the operation that he'd spent decades in the ER and had never seen an ambulatory patient with this much damage .
He spent several hours in there, went in through the front because he told me in advance it's easier to do a better job from the front, I told him do that as it's not a fashion show, it's my life to live .
The scar is bad I guess, I still cut it shaving occasionally but then I'm not handsome so what do I care next to good mobility ?

You're right that too many Doctors have God complexes and never admit they don't know or made a mistake .
