Preliminary experience of carbon fibre cage prostheses for treatment of cervical spine disorders.

The objective of this study was to assess the technical feasibility, and the clinical and radiological results of interbody fusion with a carbon fibre cage following anterior cervical discectomy. Nineteen consecutive patients, eight male and 11 female, with an age range from 28 to 75 years (mean 45) underwent anterior cervical discectomy and interbody fusion with a carbon fibre cage at one or two levels. Subjective assessment of symptomatic improvement and radiological assessment of cervical spine alignment and stability was made. All complications were recorded. The procedure was technically feasible. There was no increased morbidity and the length of procedure was no longer when compared with the similar operation but using tricorticate bone graft. All patients initially lost their radicular symptoms and the patients with myelopathy had subjective improvements of their symptoms. Fourteen of the 17 patients with neck pain showed some improvement. Bony fusion was achieved in all cases.
