Radiography was performed preoperatively, postoperatively, and after 1, 2, 4, 8, and 12 weeks. At the same time points, disk space height, intervertebral angle, and lordosis angle were measured. At 12 weeks postoperatively, the goats were killed and fused segments were harvested. Biomechanical study was performed in flexion, extension, axial rotation, and lateral bending with a nondestructive stiffness method to determine the range of motion and stiffness. All cervical fusion specimens underwent histomorphologic studies.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n All 3 cage-treated groups showed significantly higher values for disk space height, intervertebral angle, and lordosis angle compared with the autologous tricortical iliac group at 1, 2, 4, 8, and 12 weeks after surgery (P<\/jats:italic><0.05). The stiffness of hat-shaped cervical intervertebral fusion cage coated with HA+IGF-I and TGF-\u03b21 in flexion, extension, and lateral bending was significantly greater than that of the other groups (P<\/jats:italic><0.05), and the stiffness of hat-shaped cervical intervertebral fusion cage coated with HA in extension, axial rotation, and lateral bending was significantly greater than that of fusion with the bone graft and cage-only groups (P<\/jats:italic><0.05). Histomorphologic evaluation showed better fusion in 3 cage groups than in the bone graft group. In group 4 of the cage coated with HA+IGF-I and TGF-\u03b21, a slightly more advanced bone matrix formation was shown than in groups without coating.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n HA coating can improve the fusion effect of the cervical intervertebral cage, and IGF-I and TGF-\u03b21 can enhance bone fusion.<\/jats:p>\n
