Multicenter Study Comparative Study
Modern Concepts in Sagittal Curve Measurement: Comparison of Spline-based and Fixed Landmark Measurements in a Cohort of 1520 Healthy Subjects.
Retrospective multicenter study. ⋯ Our results suggest that the use of TK T1T12 and LL L1S1 is acceptable to assess spinal sagittal curvatures. However, TK T5T12 is not accurate for the thoracic curve and should be used with caution. LL L1S1 can be used to accurately assess the lumbar curve, except in Roussouly type 1.

Multicenter Study
Does operative level impact dysphagia severity following anterior cervical discectomy and fusion? a multicenter prospective analysis.
Prospective multicenter cohort study. ⋯ The location of prevertebral soft tissue swelling may impact the duration and severity of patient-reported dysphagia outcomes at up to 24 weeks postoperatively. In particular, the inclusion of C3-C4 and C4-C5 into the fusion may be associated with dysphagia severity.

Multicenter Study Comparative Study
Critical Analysis of Radiographic and Patient Reported Outcomes Following Anterior/Posterior Staged vs. Same Day Surgery in Patients Undergoing Identical Corrective Surgery for Adult Spinal Deformity.
A retrospective cohort study of a prospectively collected multicenter adult spinal deformity (ASD) database. ⋯ This investigation is among the first to compare multicenter staged and same-day surgery A/P ASD patients fused to ilium using propensity matching. Staged procedures resulted in significant improvement radiographically, reduced intensive care unit admissions, and superior patient-reported outcomes compared with same-day procedures. An interval of at least 3 days between staged procedures is associated with superior outcomes in terms of Global Alignment and Proportion score proportionality.
