Dynamic Compression of the Spinal Cord by Paraspinal Muscles following Cervical Laminectomy: Diagnosis Using Flexion-Extension MRI

<div>Postoperative T2-weighted sagittal MRI (flexion and extension): spinal cord is compressed by dorsal musculature when the neck is extended. Subaxial spinal alignment (Cobb angle) does not change with flexion-extension, reflecting rigidity of the patient’s spondylotic spine.</div>
