What can be done for osteoporosis and thoracolumbar scoliosis?

Prevention: Weight bearing exercise , proper nutrition and limited sun exposure helps to prevent osteoporosis. Even if present already, there are medications to help this condition. Osteopenia is not osteoporosis but a relative low bone mass that makes you a higher risk for osteoporosis. Finally, physical therapy and corrective posture devices will help scoliosis. Surgery is last resort for severe cases.

Treat bone loss 1st: You need to be aggressively treated for the bone loss first as there can be an increased risk of curve progression if this is not addressed. If you need a corrective surgery, there will be less risk of complications related to bone density issues as the curve correction relies on the purchase power of the spinal instrumentation at its attachment points to the spine.
