Abstract：Objective To study the influence of spinal instability after lamina decompression in symptoms and progno?sis. Methods The 76 patients were followed up for a minimum of 4 more years. The patients were divided into instability group (n=27) and non-instability (n=49) group according to the X-ray result of the final follow-up. The visual analogue scale (VAS) score, JOA score and improvement rate were compared between two groups at preoperation, 3-month after operation and the final follow-up. Results There were no significant differences in gender, age and mean follow-up time between two groups. There were no significant differences in VAS and JOA scores before surgery, 3-month after surgery and final follow-up between two groups. Postoperative VAS score decreased and JOA score increased with the increase in follow-up time (P<0.05). There were no significant differences in improvement rate [(80.0±8.8)%vs (83.6±11.7)%] and improvement ratio [81.48%(22/27) vs 61.22%(30/49)] between two groups (P > 0.05). Conclusion Although some patients show instability even with lumbar spondylolisthesis after lamina decompression on radiograph,which is no correlation with improvement of symptoms. With appropriate indications, lamina decompression is a simple and effective surgical method,which also retains the spinal movement function.
