Dynamic stabilisation of the lumbar spine with three selectable flexibilities. Quality of life and zest for life are returned. The biomechanical principle of the dynamic stabilisation of the lumbar spine consists in the control of uncoordinated and thus painful relative movements between vertebral bodies. This kind of implant does not replace any tissues. Depending on the chosen rod flexibility, structures with more or less load sharing are added. Consequently, the implantation of such a system is reversible. The connection rods made of polymeric material mimic natural ligaments (collagenous structures) and provide comparable viscoelastic properties. They behave in a similar manner under tension and flexion loads and, in addition, are also capable to carry compression loads. The demanding anchorage, in analogy, is assured with the sophisticated interaction between pedicle screw and clamp screw. Dynamic stabilisation of lumbar verte­brae and intervertebral discs through flexible rods In most cases permanent pain relief without spinal fusion surgery and without postoperative medication The mobility of the lower spine is pre­served Protection of adjacent vertebrae and discs from excessive wear and tear Rods with three levels of flexibility for optimal adaptation to the particular disease pattern Proven and gentle operation
