The objective of this study was to assess the safety, efficacy, and technical feasibility, as well as the clinical and radiological results of interbody fusion with a titanium alloy cage following anterior cervical discectomy. Forty-one consecutive patients, thirty-one males and ten females, with an age range of 30 to 75 years (mean 45) underwent anterior cervical discectomy and interbody fusion with a titanium alloy cage at a single cervical level. Both subjective and objective assessments of symptomatic improvement were made, as well as a radiological evaluation of cervical spine alignment and stability. All complications were recorded. The procedure was deemed safe, effective, and technically feasible. There was no increased morbidity and the length of procedure was no greater when compared with a similar operation, but using tricortical corticocancellous bone from the iliac crest. All patients initially lost their radicular symptoms and the patients with myelopathy had subjective improvements in their symptoms. Thirty-six of the forty-one patients with neck pain demonstrated significant improvements when compared to their preoperative status. Bony fusion was achieved in all cases.
