| Description | Cervical spinal stenosis may lead to cervical cord compression and represents the most important mechanical factor in pathophysiology of cervical spondylotic myelopathy. Medullar tissue is, however, rather resistant to compression and development of symptomatic myelopathy occurs only when higher degree stenosis is present and in combination with other pathophysiological factors, mainly dynamic compression and trauma. Asymptomatic spondylotic cervical cord compression (ASCCC) is a quite frequent finding in older population above the age of fifty. However, reliability of the methods used to verify and quantify cervical stenosis and cervical cord compression is low and clear predictors of development of symptomatic myelopathy and related indication of potential preventive surgical decompression in ASCCC have not been determined yet. The overview discusses the most frequently used methods to establish cervical spinal stenosis and cervical cord compression using imaging methods. Radiogram and especially computed tomography are important for verification of cervical spinal stenosis, while magnetic resonance imaging (MRI) is a preferable method to detect cervical cord compression. The cross-sectional spinal cord area and T2 MRI spinal cord hyperintensity are among the parameters considered to be the most closely correlated with clinical manifestation of spinal cord compression. Among newly introduced imaging modalities, MRI diffusion tensor imaging seems to be the most promising one. The presence of symptomatic radiculopathy and abnormality of motor and somatosensory evoked potentials are among generally accepted predictors of symptomatic myelopathy. The importance of imaging methods as predictors of symptomatic myelopathy development as well as benefits of preventive surgical decompression in ASCCC individuals with high risk of developing symptomatic myelopathy is to be established in future studies. |
