Abstract:
0.05). X ray film revealed that there was no loosening and displacement of internal fixation device in the test group 3 days after operation. In control group, there were 2 cases of slight graft bone displacement. Both groups exhibited a stiff bone fusion at operative level 3 months later. The intervertebral disc height of fusion level increased by (1.2?0.7) mm in the test group while decreased by (1.5?0.8) mm in the control group. CT scan revealed that there was tight contact between the internal fixation device and bone 3 days after operation. Both groups had obtained bone fusion in CT image 3 months later. Conclusion:Threaded cervical interbody fusion device made from carbon fiber reinforced PEEK has an excellent biocompatibility and can restore the intervertebral disc hight effectively with satisfactory fusion rate.
