Abstract: A spinal fixation apparatus consists of a connection means, a plurality of implant elements, washers and fastening elements. The implant elements are fastened to chines of the spine, and then the connection means is coupled on the upper side of the implant elements. Then corresponding washers and fastening elements are sequentially assembled. Finally the fastening elements are tightened on the implant elements to fasten the injured or ill-inflicted chines to the splint securely to form an integrated member to achieve a secure anchoring effect.

Abstract: An enhanced spine fixation apparatus for fixing a number of vertebrae of a spine column is disclosed. The spine fixation apparatus comprises a plurality of pedicel screws, a plurality of coupling blocks, a plurality of first securing elements, a plurality of second securing elements, a connecting rod, and a plurality of third securing elements. Each coupling block is secured on a pedicel screw by the first securing element while the connecting rod is secured on the coupling block by the second securing element. Each first securing element is fixed by the third securing element. By virtue of the provisions of a first and a second spherical convex surfaces as well as a first and a second recesses respectively on the surfaces of the pedicel screw and the first securing element as well as the surfaces of the coupling block which are being abutted, an adjustment concerning a vertical tilt angle and a horizontal rotating angle of the coupling block relative to the pedicel screw is available.
