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.

摘要翻译： 椎间盘置换假体由圆柱形笼和两个固定螺距叉组成，可以将脊椎间隙放置在所需的高度，无论是在前方进入人脊椎后方，还可以在腰椎后方进一步放置，以增加 假体的总接触面。 只需要两个仪器进行植入和最短时间，由于操作场地的渗血少，并且由于没有使用庞大的仪器，导轨等，所以允许对整个程序进行简单和持续的光学检查，以及 它结合了两种类型的笼子，圆柱形和扁平形的特点，同时消除了每种类型的缺点，从而迫使外科医生同时使用椎弓根螺钉定位后固定以获得更多的安全性。

摘要： Prosthesis for the arthrodesis of a human spine's segment of anterior and posterior (PLIF-ALIF) approach, consisting of two parts that are assembled during their implantation to the patient, interbody space after disc removal. For the anterior approach a conical threaded cage and conical forked cage, for the posterior appraoch a cylindrical threaded cage and two simple rectangular cages are used. Our prosthesis achieves the desired outcome when we tie two vertebrae, (arthrodesis), by distracting the space efficiently and stabilizing it with the screwing treaded cage, then enlarging the prosthesis surface by assembling the rectangular one. No need for further support with pedicle screws, as the previous techniques. Our prosthesis which combines both types has the characteristic that nullifies the disadvatages that existed on each type separately, that is migration, subsidence and abolishes the need for use of other support systems. Speed is also gained through simple positioning, avoiding errors and the dangers much than the previous techniques, while we expect a perfect outcome.
