Abstract
An apparatus and method for using a titanium alloy skeletal fixation system. A vertically adjustable spine screw includes an elongated u-shaped yoke on one end, with a machined female slot on each yoke side. The female slots allow ease of gripping the spine screw with a modified forceps like device. Parallel malleable metallic rods are conformed to the spinal region, then connected to the screw using an eyebolt assembly. This eyebolt assembly includes an angular rotation spacer, and a height adjustment spacer with positioning tabs. This assembly slides over each parallel rod with the bolt portion slipping into the spine screw yoke. The yoke meshes with the height adjustment spacer allowing height adjustment. The angular rotation spacer conforms to the rod and the height adjustment spacer. One or more of three different bridge assemblies transversely span the essentially parallel rods allowing lateral and angular adjustment.
