Abstract
✓ Late results of cervical disc surgery have been reported and statistically studied in 383 cases; 83% were lateral discs, 13% were central spondylosis discs, and 4% central soft discs. Central spondylosis occurred at a higher spinal level, and caused cord compression with or without weakness of the hands, but no pain. A posterior approach was used in all lateral discs, and either an anterior or a posterior approach, with or without fusion, for central discs. Preoperative myelography was always done and is recommended postoperatively in central disc surgery to evaluate the results. Our results were good to excellent in 95% of lateral discs, in 64% of central spondylosis discs, and in an unexpected 91% of 11 cases of central soft discs. There were no recurrences and no serious complications, although 20% developed other cervical or lumbar disc herniations.
