In serving as a conduit to help you locate safer, non-invasive and cheaper solutions to tough health problems, I'd like to point you toward the Clear Institute Web site run by Dennis Woggan, D.C., that provides a great deal of information about gentler treatments for scoliosis.
Dr. Woggan argues that without correction of the cervical and lumbar lordosis, correction of scoliosis is not possible, which is why the conventional medical solutions such as bracing and surgery fail, as they do not address the cause of the problem.
But Dr. Woggan also argues that spinal manipulation therapy and chiropractic adjustments may also have a detrimental effect on scoliosis, because they attempt to mobilize compensated, fixed stabilizing spinal units. Instead, he recommends a gentler technique called Whole Body Vibration Therapy.
If you suffer from scoliosis, before you consent to any surgery, I urge you to carefully review the articles section of the Clear Institute site that provides not only PDF articles that quickly explain the process, but a free 177-page book and a detailed 200-page slide show, and then consult a trusted health professional.
I'm optimistic this far gentler approach to treating scoliosis is a step in the right direction. I am a strong believer in original chiropractic philosophy that places a strong emphasis on the body's intrinsic (innate) healing wisdom and far less reliance on band-aids like drugs and surgery.
Your body has a natural healing ability, and this healing ability can be compromised if there is nerve impingement obstructing the flow of nerve impulses.
Clearing away the problems that prevent your body from healing itself is almost always both safer and more powerful than the so-called "heroic interventions" that Western medicine is based on -- drugs and surgery that treat the symptoms, without ever addressing the problems that caused the symptoms in the first place.
