- Abstract: Objective To investigate the clinical value of posterior decompression and fusion with internal fixation by nail-stick system in the treatment of lumbar spinal stenosis. Methods The clinical data of 70 patients who were admitted to the First Affiliated Hospital of Guangxi University of Science and Technology between February 2012 and February 2016 were treated by posterior pedicle screw internal fixation by nail-stick system combined with spinal canal decompression and interbody fusion with bone graft for lumbar spinal stenosis were collected. Imaging examinations were performed before and after surgery. The changes in intervertebral height, the Japanese Orthopaedic Association (JOA) scores of lumbar, the modified Macnab score, the visual analogue scale (VAS) score of low back and the Oswestry dysfunction index (ODI) were recorded. The interbody fusion was evaluated and the incidence of surgical complications was statistically analyzed. Results At 3, 6 and 12 months after surgery, the intervertebral height and JOA scores were increased, while the VAS score of low back and ODI were decreased (P<0.05). At 12 months after surgery, the proportion of grade A+B interbody fusion reached 100.00%, and the superior rate of modified Macnab classification was 95.71%. Conclusion The posterior decompression and fusion with internal fixation by nail-stick system is effective in treatment of lumbar spinal stenosis. With high safety, the proposed treatment can maintain the stability of intervertebral disc in the premise of full decompression, reduce the loss of intervertebral height, restore the lumbar functions, and reduce the disability index.
