颈椎病尸体骨赘模型的设计与建立

The design and establishment of a cadaver model of cervical spondylosis osteophytes

目的为比较不同的手术方法对颈椎病前路骨赘切除范围的影响,特制作本模型。方法参考临床颈椎病骨赘类型,将人工骨赘粘合于颈椎尸体标本上,建立颈椎病的骨赘模型12具,随机分为处理组和对照组,进行三维重建CT扫描。在CT影像上观察骨赘的影像学表现,并测量两组的椎体后缘骨赘和钩椎关节增生骨赘的数据,对数据进行比较和统计学分析。结果椎体后缘骨赘和钩椎关节增生骨赘的测量均无明显的差异(P>0.05),并且模型CT表现与临床上颈椎病骨赘增生的影像学表现一致。结论此模型比较真实地模拟了人的颈椎病增生骨赘的表现,有助于进一步研究和评价不同颈椎病前路手术方法的手术减压效果。

Objective The model was designed to compare the excision extent to the different osteophytectomies for cervical spondylosis by anterior approaches. Methods The cadaver models of cervical spondylosis were established by adhering the imitated osteophytes which were similar to human beings＇ spondylosis to cervical vertebra cadavers, and were scanned by 3-D CT. Total 12 models were divided randomly into disposal group and comparison group. In CT images,osteophytes manifestations were observed and osteophytes in posterior margin of cervical vertebra and osteo- phytes of uneovertebral joints were measured. Comparisons and statistic analyses were done in all values. Results The two groups had no significant differences in the measurement of the osteo- phytes,including the osteophytes in posterior margin of cervical vertebra and the osteophytes of uneovertebral joints. Also the models＇ images of the 3D reconstruction of computed tomography were similar to those of the cervical spondylosis in human beings. Conclusion The model imitated the truly images manifestation,and could be used to further study and evaluate the operative effects of different kinds of decompression methods.
