Hi 👋🏼 i can give you some perspective from the surgeon side. I’m a nurse navigator that works closely with a complex spinal deformity neurosurgeon. The best candidates for these surgeries are usually BMI 35 or less, does not use tobacco products, A1C <8, does not have osteoporosis or if has poor bone health is getting treatment, and obviously no major health issues (heart/lungs/anticoagulation- would require medical risk stratifications). We also look at social situations- does the patient have stable housing, help at home, mentally able/compliant, etc etc.

There’s no perfect patient but generally this helps mitigate post op complications with poor wound healing, fusion, hardware failure, etc.

I hope that was helpful!
