Hi.. Considering your age and condition( scoliosis) i would suggest you not to try any surgical interventions now. reasons being 1) if your lung functions are normal then spine correction is only for cosmetic purpose. 2) spine correction can compromise on lung expansion and can lead to pulmonary congestion. 3) post operative lung infection, pneumonia are high chances. 4) post multiple surgeries the anatomy of that region will be fibrotic and distorted and re exploring/ exposure becomes very difficult. 5) post operative neurological defects can occur. 6)Age relate anesthetic complication can occur. 7) post operative infection/ implant failure. most of these complications are doubled in older age group. If u have normal lung functions and a normal living i would suggest u to leav it alone. Thank you.
