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 col ected 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 gradual y 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.关键词
