Definitions

  • the present invention is directed to a device for the treatment of pathology in the spine and is in the field of systems that are used for instrumentation, fixation and prosthesis of the spine.
  • the present invention comprises a set of pieces that allow a posterobilateral percutaneous approach. It is not a system designed to be used through open surgery, although it could also be implanted with open surgery.
  • intervertebral disc prostheses This is the case of Spanish patents with publication number ES2310255T3 and ES2177578T3.
  • the placement in the human body of the devices can be performed by three different surgical techniques: a) Open surgery, which can be by different routes: anterior, anterolateral, posterolateral or posterior. With open surgery, the practical totality of disc prostheses or intersomatic fixators (boxes, screws, plates, bars, etc.) can be placed. To apply this type of surgery, the vertebrae must be exposed on the desired face and the device is placed with visual control.
  • b) Minimally invasive surgery It is an open surgery that uses small, less aggressive incisions and exposures. With this type of surgery, disc prostheses, intersomatic screws and transpedicular posterior fixations are also placed.
  • transpedicular posterior instrumentation systems can be placed with percutaneous surgery, the screws are introduced into the vertebrae through the pedicles posteriorly and then joined with vertical bars.
  • Intervertebral discs can be removed, (percutaneous nucleotomy), or other types of interventions on the disc, (radiofrequency nucleoplasty etc.). Punctures of the vertebrae may also be done to biopsy or cement into the vertebrae (vertebroplasties and kyphoplasty). So far, it is not known that prostheses or intersomatic fixation systems have been placed with percutaneous surgery, posterolaterally.
  • the device of the present invention has been designed to be placed by percutaneous surgery, guided by x-rays, using a new surgical technique, with appropriate instrumentation for placement, and would be included within the vertebral intersomatic fixation systems using a pathway.
  • Percutaneous and posterolateral approach This involves the stabilization of the two vertebrae without having to make a direct exposure of them. At present there is no system with these characteristics, which allows the operation of placing a device that directly stabilizes the bodies of two adjacent vertebrae percutaneously without the need for open surgery.
  • fixation device can be placed by percutaneous approach, only producing small incisions that are usually between 12 and 15 mm in length in the patient's skin.
  • the invention relates to a device for the treatment of pathology in the spine such as instability between two or more vertebrae of the spine or an alteration of the intervertebral disc, these pathologies being congenital, traumatic, degenerative, infectious or tumor origin.
  • the device comprises two rod-shaped elements that are inserted between the two vertebrae to be stabilized and that join together to give rise to a stable fixation between vertebrae.
  • This device unlike the devices of the prior art, allows the insertion piece by piece by percutaneous surgery and subsequently allows it to be mounted inside also with percutaneous surgery, not open, in the intervertebral space. Therefore, the insertion method is carried out with percutaneous, bilateral surgery to access the intervertebral space. That is, by means of surgical instruments, the posterolateral part of the disc or the vertebra is given with an orientation directed towards the center of the disc without the need to use open surgery.
  • the first tool used is a cannulated trocar that allows to reach the center of the disc from both sides.
  • a Kirschner needle is passed through the center of the intervertebral disc.
  • This needle serves as a guide in the following actions and over it they are overlapping (following through its outer part) dilators of progressively larger diameters until a dilator with the appropriate diameter to the implant is placed.
  • the implant will be constituted by the rod-shaped elements that give rise to the device of the invention and which are to be placed between the vertebrae.
  • the disc is first removed by means of known techniques and then the two rod-shaped elements that are to be stabilized are introduced between the two vertebrae that are to be stabilized. It comprises the invention through dilators that now serve as a guide.

Therefore, the internal cavities shown in the elements (1.1, 1.2, 1.3) in the form of a bar are optional and can be filled by the ossification process or by internal screws (2) as shown in Figure 9 that facilitate the connection between elements (1.1, 1.2, 1.3) in the form of a bar.
