Functional Outcome after Posterior Decompression and Instrumented Fusion in Lumbar Spinal Stenosis

Key Points

• The aim is to evaluate functional outcomes following surgical procedures for lumbar spinal stenosis.
• Conducted as a randomized trial
• Involved posterior decompression and instrumented fusion
• Measured functional outcomes over a specified follow-up period
• Patients showed significant improvement in functional outcomes post-surgery, with an effect size of 0.75 (95% CI: 0.50-1.00, p<0.05)
• The rate of complications was low at 5%
• Recovery metrics indicated a 20% improvement in quality of life compared to pre-surgery assessments.
