Fusion of spinal vertebrae requires fixation across the disk. This fixation needs to be rigid to allow the bone to grow across the region being fused. The current approach fixes this section of spine during surgery. The patient is under anesthesia and lying flat as the surgeon sets the lordosis for this region of the spine. If the lordosis is not set right the adjacent vertebrae have to adapt to correct the lordosis. This causes the fused portion of the spine to have incorrect curvature and the adjacent vertebrae to carry higher loads. Correction of this fixated section would require additional surgery. This remote operated adjustable spine device allows the lordosis of the area to be fused to be adjusted after surgery with the patient awake and in a natural standing position. The spine device also incorporates benefits for spinal sclerosis stabilization using a simpler smaller implanted device.
