Case Description: An elderly male presented with CSM/myelopathy and severe quadriparesis attributed to an unstable OO and 87° fixed, subaxial cervical kyphosis. After performing a 540° spinal cord decompression with atlantoaxial fixation, the patient did well. Conclusion: Double-level CSM due to an unstable OO and subaxial kyphosis is rare and typically requires combined 540° decompression and stabilization.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/90f1b7b1-c7fa-4d89-aa9a-ee016d4e9ff9/featured/hero-1781563480864.png","publishDate":"2020-05-09T00:00:00.000Z","doi":"10.25259/SNI_104_2020","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2020/05/10011/SNI-11-100.pdf"}
