Treatment of cervical disc disease using Cloward's technique. III. Evaluation of cervical spondylotic myelopathy in 138 cases.

Among 1,106 patients with cervical disc disease treated with Cloward's operation over a fifteen-year period, 138 patients had symptoms and signs of spinal cord involvement. The median symptom duration was one year. Nearly all had gait disturbances, 63% had spasticity of the lower extremities and 11% had various degrees of tetraplegia. Three months after surgery 78% of the patients were found to have some symptoms, but only 5% had no symptoms at all. At the time of the questionnaire (average 7.7 years postoperatively) 46% of the patients stated they were still affected by the operation. The duration of preoperative symptoms was of significance to the outcome, but age, sex, and severity of myelopathy were not. It was demonstrated that patients with medullary involvement had a higher annual mortality rate than patients with radicular symptoms, and that this rate depended on the severity of the spinal cord symptoms.

Treatment of cervical disc disease using Cloward's technique. I. General results, effect of different operative methods and complications in 1,106 patients.

During the period from April, 1965, to October, 1979, 1,106 patients with symptoms or signs of cervical disc disease were operated on using Cloward's technique. 94% of the patients alive filled in a questionnaire forwarded on October, 1980. The study revealed that 81% experienced an immediate effect of the operation, and 63% were in a better condition than preoperatively at the time of the questionnaire. It appeared that the effect of the operation 1 year postoperatively was independent of age and observation time, but the functional result and postoperative working capacity were very significantly better in young patients, but still independent of observation time. The result was independent of the number of primarily inserted grafts, cutting of the posterior spinal ligament or the finding of a free herniated disc. Use of calf bone grafts resulted in more reoperations. Primary complications were registered in 13% of the patients, reduced to 5% after 3 months. 3 patients developed a severe tetraplegia, and 6 patients died within 3 months of the operation.

Treatment of cervical disc disease using Cloward's technique. The prognostic value of clinical preoperative data in 1,106 patients.

During a fifteen-year period 1,106 patients underwent Cloward's operation due to cervical disc disease. An analysis of the clinical features showed that the diseases had a very complex pattern of symptoms and signs. In young patients a syndrome of herniated disc predominated whereas a clinical picture of "cervical spondylosis" was found more often in the elderly. It was demonstrated that best results were obtained in young patients, patients with slight symptoms and patients with monoradicular symptoms. A short duration of symptoms is essential for a good outcome, and, on the basis of the data presented, operation is recommended 3 months after the onset of symptoms of cervical disc disease, if previous conservative treatment has failed.
