Cost-effectiveness of two trial interventions for low back pain. ⋯ Risk-stratified care was not cost-effective for medium- and low-risk individuals compared to usual care. Further research is needed to assess whether there is value for high-risk individuals or for other risk-stratification approaches.

Retrospective study. ⋯ This study validated the efficacy of SAAS system to differentiate PJK/F development and good clinical outcomes. However, its differentiating power seems to be largely attributable to the function of the PI-LL component, as the PI-LL correction status better predicted PJK/F risk and clinical outcomes than SAAS.

Retrospective study of a multicentric prospective database. ⋯ This study highlights the importance of vertebral contribution to lumbar lordosis, ranging from 8 to 21% among PI groups. Lumbar lordosis decreased with aging through decreased disc lordosis in the lower lumbar spine and increased body kyphosis in the upper lumbar spine. These results may help surgeons in the assessment of sagittal alignment and the selection of operative technique to achieve surgical correction.

Retrospective analysis of a prospective multicenter Adult Spinal Deformity (ASD) registry. ⋯ ASD surgery and achieving ideal postoperative alignment do not prevent the ongoing "aging" of the non-instrumented spine. Both thoracic and global sagittal alignments deteriorate over time. Although no functional decline has been observed, the implications of these changes for surgical planning remain uncertain.

A retrospective review. ⋯ Based on PROMIS PF scores, patients with functional comorbidities do not recover to the same extent and are less likely to achieve an MCID compared to patients without baseline functional comorbidities. PROMIS-PF can help benchmark patients along their recovery, and other metrics may be needed to better understand the recovery of patients with functional comorbidities.
