Results : 76 cases were followed-up, ranging from 18 months to 3 years after postoperative, with the average of 26 months, and were photographed by X-ray at postoperative 3 days,1,3,6,9,12,18 and 24 months. Solid fusion were obtained in 74 cases. The fusion rate was 97.3%, the intervetebral height were maintained, and there were no displacement of AIFC. Two cases suffered from angulation fusion, and the cervical spine became back evagination.
