Prospective cohort study. ⋯ Our study is the first to define SCB thresholds for PROMIS PF and PROMIS PI using both fixed and dynamic cutoffs based on preoperative disability in lumbar and thoracolumbar patients. These thresholds will help in patient counseling and outcome evaluation for spine surgery research.

Retrospective observational study. ⋯ This study demonstrates that integrating patient-identified Medicare data with the ASR provides a more comprehensive assessment of outcomes for lumbar spinal fusion surgery as demonstrated through an analysis of 8,755 spondylolisthesis cases. These findings, establish the importance of multi-source data linkage to overcome the limitations of single-source registries, thereby enhancing data quality for clinical decision-making and quality improvement in spinal surgery.

Radiographic analysis. ⋯ The results showed that the bowel was positioned anteriorly at L1-5 disc levels when participants were in prone-extension and lateral decubitus-flexion positions compared with the supine position. Overall, the magnitude of bowel positional change was small and variable. These findings suggest that the bowel does not fall away from the surgical corridor when performing retroperitoneal access for single-position prone surgery compared with the lateral decubitus-flexion position.

Subgroup analysis of a retrospective clinical and animal trial [Study of different doses of methylprednisolone on functional recovery of spinal cord injury]. ⋯ The low-dose methylprednisolone regimen may have a more positive therapeutic effect on the recovery of neurological function after SCI than other regimens.
