Dynamic stabilisation with Cosmic
In cases of advanced disc degeneration with reduced height and a therefore close contact of the facets to each other (in some places piling of the facets), can lead to severe back pain. This can also be accompanied by a narrowing of the spinal canal and an instability syndrome. Often slight deformations of the spine such as rotation or spondylolisthesis, are possible. Depending on the type of the instability syndrome, different maneuvers or postures can cause pain. The most common pain-movement is the bending backward (reclination or extension) or the turning of the torso (rotation). The various causes of the pain also lead to different therapeutic strategies. Should have been determined that the pain has its origin due to a facet infiltration or a facet denervation, then a dynamic stabilisation with the discharge of the facets and the intervertebral discs by distraction (slight expansion) may be useful. Thereby a part of the pressure is transferred to the stabilisation system and the range of motion is normalised, more scientifically, the neutral zone is stabilised again. This is the zone where little force is necessary to trigger a movement. In early stages of wear this zone is widened, thereby increasing the range of motion.
The main feature of a dynamic stabilisation is that a movement of the system is possible. This flexibility is achieved in different ways, e.g. by a movable, flexible rod or movable screws. The cosmic system is about moving screws. The screw of the cosmic system work like a hinge joint, because the screw heads are moveable. This rotation is limited. Therefore, the system helps especially well in cases where pain is triggered by rotation of the hips.
