- Radiological Evaluation of Anterior Cervical Fusion with A Cylindrical Titanium Cage:

抄録
With a lesser donor-site morbidity and a better initial stability, various kinds of titanium cages have been introduced as a fusion device for the cervical spine. We have been using a threaded cylinder-shaped fusion cage for single- or two-level anterior fusion since 1994, and reviewed the radiographs retrospectively in patients who were followed up for one year or longer. In twenty cervical cases vertebrae were fixed with double cages for each disc space and in 5 cases with a single large cage. Subsidence occurred in 6 cases. Most of the patients with subsidence were older than 70 years, and the incidence was higher in cases fixed with a single large cage. Cervical lordosis decreased in 4 patients in whom the subsidence occurred. Since the cage always subsides into the lower vertebrae, it is indispensable to preserve the upper bony endplate of the lower vertebrae, especially in elder patients. A solid fusion was achieved in 96% of the cases evaluated by flexion and extension radiographs. In comparison to the previous reports using an autograft on anterior fixation, threaded fusion cages reduced the incidence of subsidence and loss of lordosis and increased the fusion rate. Our medium-term radiographic results show that the threaded titanium cage is a safe and effective device with the current anterior cervical fusion techniques.
