[Titanium implant as an alternative possibility in fusion of the cervical vertebrae--initial clinical experiences]

We report on our experience with the use of titanium for disc replacement in the cervical spine. In 52 patients a total of 55 titanium grafts were implanted. Follow-up examinations were available in 48 patients with an observation time of 14 month on average. Results of clinical-neurological examinations were excellent or good in 37 patients (77%), moderate in 9 cases (19%), while two patients (4%) showed poor outcome. Radiological follow-up examinations showed a correct position in 47 of the 48 patients. Incorrect position as observed in 1 case made operative revision necessary. According to our results, titanium grafts seem to be a useful alternative method as compared to conventional techniques of fusion. Essential advantages are simple handling, biocompatibility of the material as well as the solid bond achieved by the special qualities of the graft with respect to surface and form. Availability of different graft sizes allows tailored fusion.
