Observational Study
Proximal Junction Failure in Spine Surgery: Integrating Geometrical and Biomechanical Global Descriptors Improves GAP Score-Based Assessment.
Retrospective observational study. ⋯ BM reflects the quantitative biomechanical effect of external loads and can improve GAP accuracy. Sagittal alignments and mechanical integrated scores could be used to better prognosticate the risk of PJF.

Retrospective database analysis. ⋯ The utilization of IONM for elective lumbar surgeries continues to gain popularity. Our results indicated that IONM use was not associated with a reduction in neurological deficits and will not support the routine use of IONM for all elective lumbar surgery.

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.
