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.

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.
-
Biomechanical study. ⋯ This preliminary work demonstrates that motorized robotic cervical traction can safely and effectively apply controlled traction forces.
-
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.
