[Contribution of electromyography to the diagnosis of acute radicular or medullary cervical disc palsies (author's transl)].

Operative treatment was employed in 38 patients with cervical disc lesions. These had produced either compression of spinal cord nerves, especially C6 or C7 (22 cases), or cervical ischemic lesions (16 cases) of the centromedullary region, either isolated or associated with symmetrical, bilateral cord lesions. A study of pre- and post-operative clinical and electromyographic correlations enabled differentiation of acute cervical radioculopathies from myelopathies and definition of their progression as a function of the surgical treatment employed.
