Definitions
- H.S. Human Spine (H.S.), implant-pedicle screw, joint, divisible rod, helical spring
- the posterior fusion systems are generally used in the stabilization of the Human Spine, in f actures, degenerative spine diseases, and deformities that cause various functional, neurological problems, etc.
- the materials are screws that pass through the vertebrae's pedicles, two per vertebra and are connected to one another onto a rod with the use of a joint.
- the new technique is based on improvements of the biomechanical behavior of the points that used to be the main cause of total or partial failure of the fusion's materials.
- the screw has been designed so that on the one hand it is not as rigid as in all other systems and on the other hand it functions with implant's characteristics. Hence, it is fully embodied in the bone where it is implanted. Its body's elasticity allows the absorption of the vibration loads that are responsible either for the fatigue and breakage or for the screw's loosening in the implantation site, since micro- movements can smoothen and destroy the walls (threads) of the bone's hole where it is screwed.
- the screw's design with a hollow front section and S shaped helical spring which rotates itself at 180 degrees anti-clock wise, to all its length, pushing in its interior, the pieces of bone that it cuts into when it is being screwed clockwise, fills the internal section of the threads with the same bone where it is being implanted. This significantly reduces the demanded time for osteogenesis and its attachment on its touch points.
- connection of the screw to the rod is performed in whichever position without any tension because the rod is not solid, but divisible, thanks to the joint's mechanism which before tightening the nut allows movement towards all directions.
- we add the demanded rods one after the other, easily by opening the joint which accepts the spherical end of the rod in its two reception points, thus increasing the construction's length while tying the screws without demanding application of force or tension and contrary to the existing technique which in most cases demands the rod's bending so that the joint will be attached to the screw.
- Our system has an advantage after implantation and positioning of the whole construction compared to the existing technique, when after the assembly we perform corrective maneuvers in order to bring the H.S. back to its normal height, correct kyfosis-angle formation, or derotate the scoliosis.
- the divisible rod is a very important advantage especially in cases where we have to tie many vertebrae, making long constructions, since step by step and trough exercise of minimal force we succeed in gradual correction, contrary to the previous technique that is based on the pre-bent rod, which demands great force to be exercised hence causing the screw to be pulled out of position or breaking of the bone (pedicle).
- Fig. 1 shows the screw with the thread of different design.
- Fig. 2 shows the internal helical spring of the screw in a vertical cut, together with part of the thread.
- Fig. 3 shows the lower hollow end of the screw.
- Fig. 4 shows the rod with the two elliptic spheres on its edges.
- Fig. 5 shows the joint open and fig. 6, shows it closed having engulfed the two ball-shaped ends inside the special upper and lower cavities of the rod.
- Fig. 7 shows the screw tied to the rods and the nut secured.
- Fig. 8 shows the whole construction in position.
- Fig. 13 shows the helical internal spring 10 along the screw.
- the screw fig. 1 is hollow on its end while it is of oblique and sharp end fig. 3, so that it cuts easily through the bone. While it is clockwise advanced with the screwdriver, the cut bone is gathered by the anti-clockwise 180 degrees helical spring 10 fig. 2, which starts after point 11, fig.l, continues up to the screw's head 12 fig. 1 and forms its internal structure, which is complemented by the perimetrical threads 13, that create two cavities, rotated around themselves at 180 degrees anti-clock wise, to all the length of the helical spring, 20 and 21 fig. 2.
- the threads 13 fig. 1 lean and are attached on the helical spring.
- the screw's body can be seen on fig.
- Compartments (cavities) 21 and 22 fig. 2 that are created from the 180 degrees rotation of the spring 10, which is also the body of the screw, in the space and from the two tangent threads.
- the screw's body is not solid but helical and with the threads, on its perimeter, creates the two compartments 21 and 22 fig.
- the rod's head 40 On fig. 10 the rod's head 40 can be seen, it is placed on the two ends of the construction on the external side of the reception 17 fig. 5, unless a transverse bridge 44 fig. 11 is needed to be placed for better support and stability in rotational forces.
- the joint's hole 15 fig. 5, is not round but oblong, so that we can tighten the screw on either side, in order to correct if needed and regain the gap's lost height, through increasing or decreasing the distance between the two screws and through the selecting a rod of an appropriate length.
