Anterior cervical discectomy with and without interbody bone graft

Abstract

Fifty-one patients with symptomatic cervical disc disease refractory to conservative management were allocated at random to one of two treatment groups. The standard anterior approach devised by Cloward was used for 25 patients, and radical discectomy and foraminotomy for the other 26. All patients were followed for 6 months or longer with interview, physical examination, and radiographic evaluation. There was no difference in the success rate between the two groups. The large majority (92%) of patients in both groups were pleased with results of their operation. Because of technical factors related to operative exposure of the spinal canal and nerve roots, we prefer the Cloward procedure for patients symptomatic from advanced spondylosis and reserve discectomy without bone graft insertion for those with minimal spondylosis or soft disc herniations.
