Three Dimensional Scoliosis Correction

With evolving technique and technology, spine surgeons have developed ways to correct the degree of scoliosis deformity by 50-70%. My technique of 3-dimensional scoliosis correction has resulted in an average deformity correction in excess of 90%. I have developed several related surgical techniques to do this as safely as possible.

The spine is straightened using strong titanium rods and screws. Two 7-11 inch titanium rods are used. Fifteen to twenty bone screws measuring 1-2 inches in length are strategically placed in select vertebrae from the back of the spine. I have developed a safe technique to place these pedicle screws using minimal exposure x-ray visualization. The rods are then placed and attached to the screws with a tightening plug, followed by deformity correction.

Traditionally, scoliosis has been regarded as a 2-dimensional deformity, eg: an S-shaped curve. Classic treatment has been partial straightening of the S-curve with 2 rods and multiple attached bone hooks. The S-curve is "stretched out" along the rods, and anchored using the hooks.

The previously uncorrected "third dimension" of scoliosis deformity involves outward rotation or twisting of the vertebral bodies. Pedicle screws can be used to correct this. Sideways leverage on multiple pedicle screw heads will rotate the deviated vertebral bodies into straight alignment in the midline, achieving near-complete scoliosis correction.

My technique is unique in the fact that I can do the correction all at once with multiple specially designed linked levers (see picture). Distributing the corrective forces through multiple levers maximizes safety and curve straightening ability.

Added benefits of this technique are the need for one, instead of up to four surgical procedures. In larger curves, other surgeons may add disc removal and rib cutting surgery.

Scoliosis surgery straightens and fuses the most curved segments of the spine. The length of this stiff, fused segment is minimized by the 3-dimensional correction technique. Most spinal motion in the trunk comes from the low back. Fusing as high in the spine as possible saves more mobile discs in the low back. The three dimensional correction technique may lead to a future of less low back pain for patients, and less chance of future painful spinal degenerative arthritis.
