A spinal curvature correction device has a flexible tube having one or multiple lumens extending longitudinally through substantially the entire length of the flexible member. The lumens are a plurality of channels formed to receive multiple longitudinal members, or rods. Each rod is shaped to a desired curvature of a healthy spine or a curvature that will affect a correction of a diseased spine. The hollow, flexible tube is surgically placed along the axis of the spine and fixed. After fixation to the spinal elements is structurally stable, a plurality of curved semi-rigid rods is placed within the channels of the flexible tube. As additional rods are placed within the hollow flexible member, increased force is applied to the spine by the device, thereby moving the spine towards the desired curvature. |
