Hi doc., what should i do to cure dextroscoliosis thoracic spine?

Nothing: At 22, you should be skeletally mature. Bracing will not change the curve. At this point you need monitoring. If your curve is less than 40 degrees, it is less likely to progress. But, if it is more, you probably still need intermittent followup. If you start accelerating your curve, cardiac and pulmonay issues, get evaluated for possible surgical management.

Only if scoliosis is: Flexible & due to another reason that is forcing the spine to bend, ie spasm being generated by another issue like a kidney stone. If it is a type of scoliosis known as congenital or idiopathic, the answer is surgery if indicated but curve may not be fully corrected. Bracing for idiopathic scoliosis during growth may control curve progression and if curve over 50 degrees in adult then surgery.
