Summary
During a fifteen-year period 1,106 patients with symptoms and signs of cervical disc disease underwent Cloward's operation. Plain x-rays were performed in 94%, but the severity and extension of degenerative changes had no prognostic value. In 91 % of the patients myelography was performed and in recent years mainly metrizamide was used as it was found to be more accurate. The findings on the myelograms were correlated according to age, severity and number of affected disc levels, but were independent of the duration of symptoms. Patients with medullary symptoms were found more often than not to have an anterior indentation into the spinal canal whereas most patients with radicular symptoms had wide cervical root sleeves or lateral compression. The best outcome was found among patients with monosegmental symptoms and signs and one affected disc level on the myelogram underlining that the indication for surgery in cervical disc disease should be based on both clinical and radiological findings.
