Objective:To evaluate the effect of artificial vertebral body of the biomimetic n-HA/PA66 composites in the anterior cervical fusion for cervical spondylosis.Methods: From December of 2003 to May of 2008
53 patients with cervical spondylosis were treated by anterior semivertebra decompression
intervertebral fusion with artificial vertebral body of the biomimetic n-HA/PA66(HG)composites
fixation with titanium plate.The patients were followed-up.Nerve functional restoration
D numerieal value
intervertebral space
fusion rate of the bone graft
local response
and complication postopenative were all observed.Compared with the patients treated by bone graft and interbody fusion with titanium(TG)
the efficacy of the present tool was evaluated.Results: All patients were followed up by clinic service or telephone.The effects were conspicuous in recovering the spinal cord
D numerieal value
and intervertebral space.Fusion rate of the bone graft
local response was 100%.No complications was found.The HG was the same with the TG in improvement of the spinal cord function
D numerieal value
intervertebral space
fusion rate of the bone graft
and local response.The HG presented better results than the TG in occurrence of complication.Conclusion: Artificial vertebral body of the biomimetic n-HA/PA66 composites can recover cervical vertebra curvature and intervertebral heights
with high rate of bone graft fusion and firm fixation.
