Abstract
Abstract The present invention is a device for the straightening, fixing, compressing, and elongating of cervical vertebrae. The present invention includes a pair of rods extending to occipital plates. The occipital plates conform to the shape and inclination of the occiput. A connecting plate is attached to the ends of the occipital plates. A pedicular clamp having hooks is attached on one of the rods. A hook is connected to another of the rods. Screws are provided so as to secure the occipital plates and the connecting plate to the occiput and the connecting plate to ends of the occipital plates.
