ABSTRACT
The spinal stabilization systems could be used with minimally invasive surgical techniques, and provides flexible support of the lumbar spine while treating spinal degeneration and mild forms of spondylolysthesis [6]. Posterior stabilization systems act as a spacer which placed between two spinous process restores the natural height of the disc, taking the pressure off the intervertebral disc and associated structures. It also allows decompression of the nervous structures while maintaining normal movement of the spine [5, 7].
