Effectiveness of Surgery for Degenerative Lumbar Spinal Stenosis: A Systematic Review

Background: Lumbar spinal stenosis is common condition. Many similar treatment procedures have been described. In managing spinal stenosis surgery has expanded dramatically in the last two decades. Aim of the study: Assess the safety and efficacy of operative and invasive therapies for people experiencing degenerative LSS. Patients and Methods: PubMed, Embase, Web of Science, and the Cochrane library were used to find relevant clinical research. Participants in such studies were 60 years old or older and had degenerative lumbar spinal stenosis. Results: All studies were randomized controlled trials. There were 974 patients. As regard Outcomes measures after surgical treatment, significant improvement in functional outcome and scores. Outcome of patients were measured pre and post operation by oswestry disability index (ODI) score in 8 studies with mean pre operation score 43.7 and post operations score decreased to 26.06. Visual analog scales (VAS) were used in 3 studies with preoperation mean score 5.49 and decreased post operation to 22.5. EQ-5 D was used by 1 study and mean preoperation score was 0.29 which increased to 0.58 postoperation.SF-36 scores were used to assess patient’s outcome after surgery and showed that mean SF-36 physical pre was 34.7 decreased to33.1, mean SF-36 mental pre was 58.6 increased to 66.4 and mean SF-36 pain pre was 31.2 and changed to34.6. Conclusion: Surgery showed higher effectiveness and functional outcome improvement and scores among included studies. As regard Patient’s satisfaction reported in three studies in 114 patients was satisfied.
