Randomized Controlled Trial Multicenter Study Observational Study
Long-term outcomes of lumbar spinal stenosis: eight-year results of the Spine Patient Outcomes Research Trial (SPORT).
Randomized trial with a concurrent observational cohort study. ⋯ Patients with symptomatic spinal stenosis show diminishing benefits of surgery in as-treated analyses of the randomized group between 4 and 8 years, whereas outcomes in the observational group remained stable. Loss to follow-up of patients with worse early outcomes in both treatment groups could lead to overestimates of long-term outcomes but likely not bias treatment effect estimates.

Randomized Controlled Trial Multicenter Study Comparative Study
Minimally invasive decompression versus x-stop in lumbar spinal stenosis: a randomized controlled multicenter study.
Prospective randomized controlled multicenter study. ⋯ Both MID and X-Stop led to significant symptom improvements. There were no significant clinical differences in effect between the methods at any of the follow-up time points. X-Stop had significant higher risk of secondary surgery. Complication was more severe for MID.

Randomized Controlled Trial
Monitoring the quality of robot-assisted pedicle screw fixation in the lumbar spine by using a cumulative summation test.
Prospective randomized controlled trial. ⋯ First, this study demonstrates the adequacy of quality control of robot-assisted pedicle screw fixation even early in the application period based on the CUSUM analysis. Second, the CUSUM test can be a useful tool for monitoring of the quality of procedures related with spine surgery.

Randomized Controlled Trial Comparative Study
A comparison between unilateral transverse process-pedicle and bilateral puncture techniques in percutaneous kyphoplasty.
A prospective comparative study. ⋯ Both bilateral and unilateral PKP are relatively safe and provide effective treatment for patients with painful osteoporotic vertebral compression fracture. However, unilateral PKP received less radiation dose and operation time, it also offered a higher degree of deformity correction and resulted in less complication than bilateral PKP.
