Abstract
For the purpose of facilitating correction of front-to-back and lateral vertebra curvature in scoliosis and the like, vertebra screws are passed through vertebra plates with spikes that dig into the sides of vertebrae and are screwed into each vertebra. The vertebra screws have rod passage holes in their heads, respectively, which holes are partially open on the side. A screw hole is provided at the top surface of each head. Rods are inserted into and passed through all the rod passage holes via the side openings in the heads of all the vertebra screws, the set-screws being each screwed into screw hole formed in the top surface of the head of the vertebra screw for the purpose of fixing the rods to the vertebra screws.
