Multicenter Study
Machine Learning for Benchmarking Adolescent Idiopathic Scoliosis Surgery Outcomes.
Retrospective cohort. ⋯ Classification of benchmark outcomes is improved with ensemble ML techniques and may provide much needed case-adjustment for a surgeon performance program. Precise estimates of health-related quality of life scores and continuous variables were not possible, suggesting that performance classification is a better method of performance evaluation.

Multicenter Study Observational Study
A Diagnostic Biomarker for Cervical Myelopathy Based on Dynamic MRI.
Multicenter prospective observational study. ⋯ Significant increases in ADC values between the control and pathologic segments were found for both groups in neck extension only. This may serve as a diagnostic tool to identify early changes in the spinal cord related to myelopathy to indicate potentially reversible spinal cord injury and support the indication for surgery in select circumstances.

A prospective multicenter study. ⋯ JOA, JOACMEQ, and VAS scores were not significantly different between those with, and without, loss of cervical lordosis. Preoperative small eROM and large OPLL may represent factors associated with loss of cervical lordosis after laminoplasty in patients with OPLL.

Multicenter Study
Quantifying the Contribution of Lower Limb Compensation to Upright Posture: What Happens if Adult Spinal Deformity Patients Do Not Compensate?
This is a multicenter, prospective cohort study. ⋯ Removal of lower limbs compensation revealed an unsustainable truncal malalignment with two-fold greater SVA.
