Abstract
A rod group includes a plurality of first rods that has an arcuate first curve, the first rods having mutually different lengths; and a plurality of second rods that has an S-shaped second curve, the second rods having mutually different lengths. The first rods and the second rods have shapes for treatment of scoliosis by (i) guiding the postoperative apex of the thoracic kyphosis to be located at the thoracic vertebrae T6 to T8, and (ii) guiding a postoperative apex of the thoracic kyphosis to be located at a position different from a preoperative apex of the thoracic kyphosis and the second rod each have a shape extending along an anatomically normal spinal column arrangement.
