Cervical spine spondylosis is a degenerative condition caused by narrowing of the spinal canal and nerve root compression, potentially leading to myelopathy. This study assessed cervical spine canal-to-body ratio using lateral X-rays in healthy individuals (age 25–35) and 12 patients with myelopathy. Healthy canal-body ratio ranged 0.97–1.02, while myelopathy patients averaged 0.8. Sagittal diameter was 18–21 mm in normal cases and 9–11 mm in stenosis. This simple, cost-effective method can be applied in peripheral settings. © 2020 Elsevier B.V., All rights reserved.
