Diagnostic and Therapeutic Options in Stenosis of the Cervical Spinal Canal
Wrong approaches to diagnosis and delays of several years in diagnosis are not uncommon in spinal canal stenoses. Apart from the case history and the clinical findings, it is indispensable that cervical X-rays be taken in four planes. In accordance with direct or indirect criteria of Stenosis, myelography (MG), computed tomography (CT) or magnetic resonance imaging (MRI) can then be employed specifically. Ultrasonographic techniques are less reliable. Elektröphysiologically, functional disorders of the spinal cord can be imaged by means of SEP and if necessary functional disorders of the nerve roots by EMG. Specific advantages and disadvantages of further diagnostics are summarized in Table 1, on the basis of our own experience with 23 patients.
