I did have osteoporosis but now osteopenia. This is not the cause of my scoliosis; mine started at age 11. I am 83 and had an old corrective surgery in 1956 and a revision with hardware in 2002. I got my best help from National Scoliosis Foundation website. Schroth will help reduce pain and strengthen your back but not sure it’s safe with osteoporosis.
What country are you in?
