Systematic review and meta-analysis. ⋯ There is evidence of short-term efficacy (moderate for pain and small for function) of opioids to treat CLBP compared with placebo. The effectiveness and safety of long-term opioid therapy for treatment of CLBP remains unproven.
-
Retrospective review of prospectively collected data. ⋯ For Lenke 1 and 2 curve patterns, improved percent correction of major coronal curve was noted in the high-screw density cohort. Although statistical significance was reached, it is unclear whether screw density resulted in clinically significant differences in patient-reported outcomes.
-
Retrospective cohort. ⋯ We could not demonstrate that the training of new (or newly promoted) residents is associated with an increase in the adverse events of spine surgery. Safeguards that have been put in place to ensure patient safety during this training period seem to be effective. Although adverse events were more common among cases with resident involvement than among cases without resident involvement, our data suggest that this association is more likely a product of the riskier population of cases in which residents participate than of the resident involvement itself.
-
Prospective cohort study. ⋯ Assuming that good spinal cord pulsation represents good spinal circulation, these results suggest that the supine position will provide the most favorable condition for recovery of the cervical spinal cord.

Retrospective review of prospectively collected databases. ⋯ On the basis of the simplified collection system, the rate of mortality for spinal deformity surgery was 1.50 per 1000 cases. Compared with the detailed system, the simplified system had significantly improved compliance and similar mortality rates. Although the simplified system is limited by less data collected, it achieves better compliance and may prove effective, especially if supplemented with focused data collection modules.
