Retrospective longitudinal cohort study. ⋯ Patients with poor preoperative health-related quality of life were more likely to achieve improvement in SRS-22r parameters after extensive corrective fusion surgery for ASD. Achieving postoperative sagittal alignment increased the likelihood of achieving MCID for the SRS-22r Subtotal domain.Level of Evidence: 3.

Observational Study
The Association of "U.S. News & World Report" Hospital Rankings and Outcomes Following Anterior Cervical Fusions: Do Rankings Even Matter?
Retrospective observational study. ⋯ Despite the higher charges and costs of care at ranked hospitals, these facilities appear to have similar outcomes as compared to unranked hospitals following elective ACFs.Level of Evidence: 3.

Retrospective cohort study. ⋯ Addition of the CPT-based categorization method to MS-DRG coding provides an enhanced method to evaluate the association between predicted and actual cost when using linear regression analysis to assess cost variation in spine surgery.Level of Evidence: 3.
-
Prospective comparative study. ⋯ Our findings confirm the previous findings of literature regarding the alteration in gait patterns in scoliosis patients when compared to normal individuals. However, the lack of difference in gait analysis variables between AIS and congenital scoliosis patients suggests that this alteration in gait is secondary to the existence of the deformity and does not correlate with the onset or etiology of deformity.Level of Evidence: 2.

Observational Study
Factors Associated with Progression to Surgical Intervention for Lumbar Disc Herniation in the Military Health System.
Retrospective cohort. ⋯ LDH compromises military readiness and negatively impacts healthcare costs. MHS beneficiaries with LDH have a good prognosis with approximately 88% of patients successfully completing conservative management. However, strategies to improve outcomes of conservative management in LDH should address risks associated with both patient and facility characteristics.Level of Evidence: 4.
