Retrospective cohort study. ⋯ While post-admission outcomes and inpatient complications were similar across PNI groups, PNI on admission provides useful insight into the severity of infection and predicts the need for operative intervention in patients presenting with native spine infection.

Retrospective cohort study. ⋯ Three-level lumbar decompression patients who underwent three-level fusion were found to be at significantly greater odds of 90-day postoperative adverse events, readmissions, and five-year reoperations relative to those undergoing one-level fusion. The current data support the concept of limiting fusion to the levels with specific indications in the setting of multi-level lumbar decompressions and not needing to match the decompression and fusion levels.

Retrospective observational study. ⋯ 3.

Biomechanical Study. ⋯ This biomechanical investigation demonstrates that constructs that cross the cervicothoracic junction experience less overall spinal motion in flexion-extension compared to those that terminate at C7. However, contrary to prior studies there is no difference in cranial and caudal adjacent segment motion. Surgeons should make clinical decisions regarding the caudal extent of fusion in multi-level posterior cervical fusions without major concerns about adjacent segment motion.

A retrospective study. ⋯ CO showed a greater SA correction and achieved a broader range of SA correction angles than PSO with no difference in the incidence of major complications. In addition, the EBL and the frequency of RF were lower. Based on these results, we expect that CO can serve as a promising surgical alternative to PSO for spinal deformity correction among patients with ASD.
