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.

Retrospective study of a consecutive series of patients with thoracolumbar hyperextension injuries (TLHIs) complicated by diffuse idiopathic skeletal hyperostosis (DISH) presenting to a single institution during a 9-year period. ⋯ To our knowledge, this is the largest series of TLHIs in DISH-altered spines in literature. The study helps to understand controversial findings in literature about morphological properties of TLHIs in DISH-affected spines. Surgeons should be aware of preexisting alterations in traumatized spines and the impact on therapeutic decisions. Because of the "aging population" and implications of metabolic diseases on an "aging spine," the incidence of TLHIs in DISH will probably rise.

A cross-sectional study on baseline data. ⋯ The Dutch ODI version 2.1a is a valid and valuable tool for the measurement of functional status and disability among Dutch patients with chronic low back pain. This translated condition-specific patient-reported outcome measure version is recommended for use in future back pain research and to evaluate outcome of back care in the Netherlands.
