Lumbar motor unit instability caused by the scope of nociceptive related to the soft tissue both inside and outside spinal canal and instability junction,so the scope of treatment should take into account the multi-faceted three-dimensional.

Study on treatment of lumbar instability by posterior inter body fusion combined with pedicle screw;

Methods Fifteen patients, including 4 lumbar spine slippage and 11 lumbar instability, underwent the lumbar pedicle screws placement and used 68 screws.

Objective To evaluate the method and outcome of the treatment of lumbar vertebral instability by posterior internal fixation with threaded fusion cage.

My paper is a brief summary on the application of the dynamic stabilization in lumbar instability syndrome operation.

Objective To observe the clinical efficacy of posterior intervertebral fusion with lumbar fusion cage for lumbar disc herniation combined with low lumbar instability.
