    摘要： Posterior fusion system, screw-rod-connector, whose screw the body that is screwed in the bones is characterized by clockwise threads, helical attached to an anti-clockwise rotating central spring consisting of a core and anti-clockwise wings. The screw functions as an implant, since it is incorporated in the surrounding spongiosa bone completely, with the two rotated at 180 degrees helical compartments that allow communication and contact in a 360 degrees direction. Its front section is hollow and slightly pointed. Its connection is accomplished with a joint and divisible rod with free movement before the nut's final tightening, separately for each vertebra, thanks to two receptions of the joint and the rod's spherical heads. This eases the placement and also the rod's application without any tension and after tightening the nut it immobilizes it in any position and allows all reduction handling, before the final tightening. The whole system assembled in this way and with a flexible screw, which withstands more fatigue than the solid one, is incorporated much faster because the screw acts as an implant and thus withstands more fatigue. Finally, it increases the construction's longevity, reducing loosening danger from the implantation site.

    摘要： Prosthesis for the replacement of a complete vertebral unit, whose assembly allows total removal and replacement of all the vertebral body's elements that are the pedicles with the joint facets and the lamina and has interconnection capability to a posterior fusion system which carries special screws 31 which has the capability of connection to a posterior fusion system, consists of the front part, which is of octagonal shape as in fig. 1 and special designed screws 31 that can connect it to the posterior fixation pedicle screw system and thus create a complete construction which aims at solving the problem of migration in cases of replacement of a complete vertebral unit.
    Hence, we avoid the danger of two independent fusions, which are currently used and are not stable enough when for some reason, usually tumor of the H.S., the laminas, the joints, and the pedicles have been destroyed besides the body. In this case, instability is great and demands minimization of migration's danger. The connection of the posterior pedicle fusion to the prosthesis at the front, and the new way of expanding its length with a toothed mechanism on the two ends where they touch the final plates, ensures quick insertion, and great stability which is necessary in operations of this type.

    摘要翻译： 完整的脊椎单元的替代假体，其装配允许完全移除和替换具有关节面和椎板的椎弓根的所有椎体的元件，并且具有连接到后部融合系统的互连能力，所述后部融合系统承载具有 连接到后融合系统的能力由前面部分组成，其前部是八边形，如图1所示。 1和特殊设计的螺钉31可以将其连接到后固定椎弓根螺钉系统，从而创建一个完整的结构，其目的是在更换完整椎体单元的情况下解决迁移问题。 因此，由于某种原因，我们避免了两种独立融合的危险，因为某些原因，通常H.S.，椎板，关节和椎弓根的肿瘤除了身体外都被破坏。 在这种情况下，不稳定性很大，要求最小化移民的危险。 后部椎弓根融合与前方假体的连接，以及两端接触终板的齿形机构的长度扩大的新方法，确保快速插入，并且在操作中必需的高度稳定性 这个类型。

    摘要： Intervertebral disc replacement prosthesis consisting of a cylindrical cage and two securing pitch forks that can be placed in the inter-vertebral space to desired heights wherever in the Human Spine with anterior approach and, also on the Lumbar Spine with posterior approach in order to increase the total contact surface of the prosthesis. Only two instruments are demanded for its implantation and minimum time, it allows easy and constant optical checking of the whole procedure, due to less bleeding on the operating field and also due to the fact that no bulky instruments, guides etc. are used, and it finally combines the characteristics of both types of cages, cylindrical and flat ones, while it abolishes the disadvantages that each type has thus forcing surgeons to resort in positioning posterior fixation with pedicular screws at the same time for more safety.
