Input on odontoid type-2 fracture

[edge10]

I would like get  some input on methods for selecting a surgeon for the examination/consultation for a c2 odontoid type-2 fracture for my 89 y.o. mother.   In my search am finding relatively few surgeons or hospitals that list this type of fracture. A more general term cervical fracture or "broken neck" is sometimes listed.

My mother got the fracture in a fall and there was a CT and an MRI done at the time.  The fracture was stable, she had no symptoms, and full strength in all of her limbs.  We decided on conservative non-surgical treatment and instead have her wear a cervical collar for 12 weeks. The 12 weeks has passed she is recovering well.  I would appreciate any guidance or input on the method for a surgeon selection and/or treatment for the ontondoid type 2 fracture.
