SpineJack® offers surgeons a controlled and minimally invasive solution to treat vertebral compression fractures. It allows a safe anatomical restoration and following stabilization of the vertebra.

SpineJack® gibt es in drei Grössen zur bestmöglichen dreidimensionalen Anpassung an die Anatomie der Wirbelkörper.

 

As for any other weight-bearing joint, spine fractures deserve to be treated by a stable anatomical reduction and a stabilization. These both steps combined allow for a biomechanical restoration due to an early mobilization and weight bearing. Anatomical reduction means restoration of the geometry of the whole vertebra, that is cortical ring AND endplates.

• Cortical ring reduction consists of vertebral angle restoration which is the key for kyphosis management and consecutive adjacent fracture avoidance

• Vertebral endplate restoration has been described as having a positive influence on disc creeping, disc degeneration, compensatory curvatures or facet joint arthritis.

Several clinical and epidemiological studies have shown a correlation in between vertebra deformation and clinical problems such as post-traumatic kyphosis, which has been depicted as one of the most potentially serious post-traumatic deformities. A SpineJack® treatment can relieve patients mostly from this pain.

Within this context, VEXIM® has designed the SpineJack® implant to provide clinicians with a fully controlled solution for VCF treatment enabling first an anatomical reduction and second a safe stabilization.

SpineJack® is available in three sizes for the best three-dimensional adaption to the vertebral anatomy.

 

How does SpineJack® work?

  • „The titanium-alloy implant is introduced transpedicularly. The following cranio-caudal expansion of SpineJack® achieves the controlled restoration of the sagittal angle and the endplates without anteopulsion or retropulsion of the fragments.
  • „This restoration of the vertebral height and the endplates is maintained until the vertebra is stabilized by highly viscours bone cement.
  • „The resoration of the vertebra can be precisely measured b 3D-reconstruction as well as pre- and post-operative CT scans. The level of restoration is visualized by a color code.

Ideal indications and benefits

  • SpineJack® can be used in the treatment of vertebral compression fractures from type A1.1 to A3.1 (according to Magerl classification). An application for type A3.2 and A3.3 is not planned so far.
  • Cranio-caudal anatomical restoration of the cortical ring and the endplates
  • Maintaining the restoration
  • Preserving the trabecular bone structure

Promising longterm results

First clinical Studies indicate a lower rate of adjacent fractures, compared to traditional methods.
