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. By way of the third securing element, the first securing element is prevented from loosening.

Enhanced spine fixation apparatus

An anterior spinal fixation system comprises a pair of equal upper and lower vertebral plate systems and at least two rods arranged in parallel. The upper and lower vertebral plate systems each includes a staple vertebral plate and a universal cover plate which are jointed firmly with each other to retain the ends of the rods. Furthermore, the anterior spinal fixation system of the present invention may also comprise at least one connector plate system retain in the middle of the rods so as to enhance supporting strength and effect of anti-twist.

An intramedullary nail fixation apparatus and its fixation method, the apparatus including a tubular intramedullary nail having a plurality of equiangularly spaced piercing points, and a plurality of flexible screws respectively mounted in the intramedullary nail and forced to fix the intramedullary nail to the marrow cavity of the bone to be fixed, each flexible screw having a rounded stem convenient for rotation, and a self-tapping screw tip at one end of the rounded stem convenient for being forced out of the intramedullary nail through one piercing point and then threaded into the wall of the bone upon rotation of the respective flexible screw. The invention relates also to the method of the fixation of the apparatus.

A load sensor inserted between two bones for sensing a stress exerted on the load sensor includes a body, and a load transducer mounted in the body for transducing a strain thereof resulting from the stress into an electronic signal. Such load sensor can detect a stress exerted on a bone graft bone and/or the interaction of the bone graft and spine implant to improve curative effects and increase the successful rate of a bone graft operation.
