摘要:
A system provides for lateral translational corrective force(s) and/or derotational corrective force(s) on a spinal column and includes highly adaptive hardware for connecting the system to the spinal column, where the hardware facilitates a more natural range of motion within pre-selected limits and application of such lateral translational and/or derotational corrective force(s). The upper and lower vertebral segments retain freedom of movement while an apical or restricted segment is restricted from relative vertebral movement. A central segment controls primary rod roll while the rod is free to change in pitch, yaw and roll at the upper (superior) and lower (inferior) segments.
