摘要：

背景：有关成人椎体钉进钉点的报道较多，但都只有一般性的描述，且由于不同种族、节段等差异，椎体形态变异较大，其置钉位置的选择也不一致。
目的：通过CT扫描结合逆向工程软件建立下胸椎三维立体模型，数字化测量成年国人中下段胸椎侧前方椎骨相关解剖位置CT数据。
方法：收集非脊柱疾患病例CT资料，利用Mimics软件建立国人完整中下段胸椎(T4-T12)三维立体模型，测量椎体正中冠状面左、右缘高度，正中矢状面前、中、后缘高度，椎体上终板矢状径及横径，椎体下板终矢状径及横径。
结果与结论：国人中下段胸椎椎体上、下终板矢状径及横径均随椎序的增加而增大。在中、下段胸椎椎体上缘置钉，椎体螺钉的选择有一定的规律；由于椎体的横径始终大于矢状径(3.0-4.0 mm)，建议在取材和修剪移植松质骨块时应将骨块修成横行的长方体(长大于宽3.0-4.0 mm)。临床中下胸椎侧前方固定时应参考以上数据选择合适的纵行棒进行固定。

Abstract:

BACKGROUND: There are many reports on the entrance point of adult vertebral screw, but most of the reports are the general description. Because of the differences in races and segments, the shape of vertebral body is various, and the choice of screw placement position is also varied. 
OBJECTIVE: To construct the three-dimensional model of lower thoracic vertebra through CT scanning combined with reverse engineering software, and to digital measure the correlated anatomic CT data of the lateral anterior middle and lower thoracic vertebra of Chinese adults. 
METHODS: The CT primary data of non-spinal disorders cases were collected and the data were used for the establishment of three-dimensional model of complete middle and lower thoracic vertebra (T4-T12) of Chinese people with Mimics software. The coronal plane left and right edge height, midsagittal anterior, median and posterior edge height, sagittal diameter and transverse diameter of the upper vertebral endplate and the lower vertebral endplate were measured.
RESULTS AND CONCLUSION: The sagittal diameter and transverse diameter of the upper and lower vertebral endplates were gradually increased with the increasing vertebral sequence. The vertebral screw selection had certain regularity when placing in the anterior middle and lower thoracic vertebra; because the transverse diameter of vertebra bodies was always bigger than sagittal diameter for 3.0-4.0 mm, bone graft should be shaped into laterigrade cuboid (the length should be larger than width for 3.0-4.0 mm). The clinical lateral anterior approach internal fixation of middle and lower thoracic vertebra should refer to the data above.
