ADOLESCENT IDIOPATHIC SCOLIOSIS
These are before and after X-rays and clinical photos of how we can correct scoliosis in three dimensions and how a rib hump can be minimized by this technique.

Spine surgeons have developed different methods and techniques that can now correct the degree of a spine with scoliosis deformity by 50-70%. 3-D scoliosis corrections can even average in corrections by up to 90%.
The technique used to help straighten a spine is by using titanium rods and screws. Depending on the severity of the scoliosis, fifteen to twenty bone screws can be placed in select locations of the vertebrae near the back of the spine. My practice has been able to develop a very safe technique that allows us to place these screws in with very little X-ray exposure, even for adolescent idiopathic scoliosis. Once the screws are inserted, the rods are then attached to the screws to allow for the spinal deformity correction.
Scoliosis is typically considered a 2 dimensional deformity. The best example would be such as an S shaped curve. Spinal deformity treatments are thus often 2 rods attached to hooks to straighten out the S-curve by stretching it out.
3-dimensional scoliosis correction now takes into play the rotation or twisting over the vertebrae. The easiest way to do this is through pedicle screws. When you can leverage screw sideways, one can now rotate the vertebrae into a better alignment and correcting the spinal deformity to nearly 90%.
By distributing these pedicle screws through multiple levers, a spinal deformity surgeon can perform spinal correction all at once and still maintain a high level of safety and ability to straighten the back. This also decreases the amount of surgical procedures from 3 down to 1.
