Multicenter Study
Biomechanical Effects of Thoracolumbosacral Orthosis Design Features on 3D Correction in Adolescent Idiopathic Scoliosis: A Comprehensive Multicenter Study.
Multicenter numerical study. ⋯ The corrective features of various scoliosis braces were objectively compared in a systematic approach with minimal biases and variability in test parameters, providing a better biomechanical understanding of individual passive mechanisms' contribution to 3D correction.

Multicenter Study
Rates of Loosening, Failure, and Revision of Iliac Fixation in Adult Deformity Surgery.
Retrospective cohort review of a prospective multicenter database. ⋯ Lumbopelvic fixation failure rates were high following ASD correction, and associated with lesser clinical improvements. S2AI screws were more likely to demonstrate loosening, but less commonly associated with rod fractures at the lumbopelvic region.
-
A prospective, multicenter study. ⋯ Tc-MEP alert during position change is an important sign of spinal cord injury due to alignment change at the upper thoracic spine. Tc-MEP monitoring before supine-to-prone position change was necessary to prevent spinal cord injury in surgeries for T-OPLL.
-
Retrospective cohort study. ⋯ Despite extensive research examining risk factors for PJK/PJF and increasing utilization of intraoperative PJK prophylaxis techniques, the rate of radiographic PJK and/or PJF did not significantly decrease across the 10-year enrollment period of this ASD database.

Multicenter Study
Predictors of Dysphagia After Anterior Cervical Discectomy and Fusion: A Prospective Multicenter Study.
Multicenter prospective study. ⋯ Dysphagia is common immediately after ACDF, but rates of prolonged dysphagia are similar to preoperative baseline rates. We identified dysphagia rates over time and several patient factors associated with development of short- and long-term postoperative dysphagia.Level of Evidence: 3.
