Reoperation rates and risk factors for revision 4 years after dynamic stabilization of the lumbar spine

The concept of dynamic stabilization (DS) of the lumbar spine for treatment of degenerative instability has been introduced almost two decades ago. DS follows the principle of controlling movement in the coronal plane by providing load transfer of the spinal segment without fusion and at the same time reducing side effects such as adjacent segment disease (ASD). So far only little is known about revision rates after DS due to adjacent segment disease (ASD) and screw loosening (SL).
