Association of Preoperative Cervical Spine Alignment With Spinal Cord Magnetic Resonance Imaging Hyperintensity and Myelopathy Severity

Abstract

Global sagittal alignment and SVA interactively associate with quantitative MRI spinal cord signal abnormalities and worse CSM-related disability. The reciprocal relationships of SVA effect in patients with kyphosis and those with lordosis may reflect an optimal spinal alignment to achieve during surgical management.
