Abstract
Anterior cervical surgery for treatment of lateral disc herniation was studied in 253 patients surviving 1-7 yr postoperatively. Excellent or good results were obtained in 67%. Although 77% initially noted complete relief of symptoms after surgery, 38% subsequently developed one or more recurrent symtoms at some time during the follow-up period. The overall results of surgery for soft disc cases were no different from the results for hard discs, although significantly more hard disc cases required postoperative conservative treatment. Surgery after anterior fusion was no different than after anterior discectomy alone. Overall postoperative complications were more frequent and hospitalizations were longer in the patients with fusion. Patients with multiple-level surgery were statistically similar to those with single-level surgery. None of the 9 preoperative clinical features reported to influence anterior cervical surgery consistently affected outcome in this series.
