Abstract Objective To investigate the effect of decompression and non-fusion dynamic stabilization in the treatment of spinal stenosis with degenerative lumbar scoliosis (DLS), and provides a new reference for clinical practice. Methods From January 2014 to June 2016, 189 patients with lumbar spinal stenosis admitted to the Department of Spine Surgery of the People′s Hospital of Inner Mongolia Autonomous Region were selected, 66 DLS patients were randomly divided into the non-fusion dynamic stability group (n = 34) and the fusion group (n = 32) by simple random sampling. Patients in the non-fusion dynamic stability group received decompression surgery and Dynesys system non-fusion stability surgery, while patients in the fusion group received fusion surgery. Preoperative general data, fixed segment, intraoperative mean operation time, intraoperative blood loss, and average hospital stay were statistically analyzed. Postoperative efficacy (sacrum Angle, thoracic kyphoid Angle, and mobility, etc.) and related complications were statistically evaluated. Results Patients in the non-fusion dynamic stability group underwent decompression and non-fusion stability surgery in 64 segments, while patients in the fusion group underwent fusion fixation in 67 segments. The mean operation time, intraoperative blood loss, average length of hospital stay and time of underground activities of the patients in the two groups were compared, the fusion group were greater than those of the dynamic non-fusion group, and the differences were statistically significant (P ＜ 0.05). The mean values of sacral Angle, thoracic kyphosis Angle and L3/4 intervertebral activity in the final follow-up of the dynamic non-fusion group were all higher than those in the final follow-up of the fusion group (P ＜ 0.05). Visual analogue score (VAS), leg pain VAS and Oswestry disability index questionnaire (ODI) score of the dynamic non-fusion group at the last follow-up visit were all lower than those of the preoperative fusion group (P ＜ 0.05). Conclusion Stenosis associated with mild to moderate scoliosis (angle of < 30 °) in middle-aged and elderly patients, the clinical curative effect of implementation of the fusion decompression technology is better than fixed.
