【摘要】：背景:胸腰段(T11-L2)由于其特殊的解剖结构与生物力学特征而容易发生损伤,因此术前充分的了解椎弓根形态及术中寻找有形的、恒定的、且顺应椎弓根轴线的进钉点标志对安全置入椎弓根钉极为重要。目的:CT扫描并测量汉族与维吾尔族男性胸腰段椎弓根应用解剖的相关参数,为临床应用椎弓根螺钉内固定提供应用解剖学资料。方法:用CT对120例成年男性受检者(汉族60例,维吾尔族60例)的胸腰段(T10-L3)椎体进行扫描,扫描后的图像行三维重建,在骨窗窗位下使用浏览器中角度及长度测量工具测量并记录横断面椎弓根宽度(TPW),椎弓根轴线长度(PAL),椎弓根横断面角(TPA)和椎弓根矢状面角(SPA)。同时记录受检者的年龄、身高。以上数据运用SPSS 13.0软件进行统计学处理。结果与结论:(1)汉族组在T12和L1节段的横断面椎弓根宽度均值大于维吾尔族;(2)汉族组在T12和L2节段的椎弓根横断面角均值大于维吾尔族;(3)汉族组在T11和L1节段的椎弓根轴线长度和椎弓根矢状面角均值大于维吾尔族,差异有显著性意义(P0.05)。(4)实验所测量汉族与维吾尔族男性胸腰段弓根各径线的数据部分有差异,任何椎弓根形态测量所得的均数值只能为安全置入椎弓根螺钉提供一个参考。在椎弓根螺钉置入术前行CT测量相关参数,并制定个体化置钉方案,能有效降低因误置而导致的不必要的术后并发症发生率。
[Abstract]:Background: the thoracolumbar segment T11-L2) is prone to injury due to its special anatomical structure and biomechanical characteristics. It is very important to safely insert pedicle screw into the pedicle of Han and Uygur males. Objective to measure the relevant parameters of applied anatomy of thoracic and lumbar pedicle of Han and Uygur males. Methods: the vertebral bodies of 120 adult male subjects (60 Han and 60 Uygur) were scanned by CT for pedicle screw fixation. The angle and length measurement tools in the browser were used under the bone window position to measure and record the transverse pedicle width, pedicle length, pedicle axis length, pedicle cross-sectional angle (TPAA) and pedicle sagittal angle (spa). The age of the subjects was also recorded. Height. The above data were statistically processed by SPSS 13.0 software. Results and conclusion the average transverse pedicle width of the Han group in T12 and L1 segments was larger than that in the Uygur group.) in the Han nationality group, the pedicle width in the T12 and L2 segments was higher than that in the Han nationality group in the T12 and L2 segments. The length of pedicle axis and the sagittal angle of pedicle in T11 and L1 segments of Han nationality were larger than that of Uygur. There was significant difference in the diameter of thoracic and lumbar arches between Han and Uygur males. The average value of any pedicle shape measurement can only provide a reference for the safe placement of pedicle screw. Before the pedicle screw implantation, the relevant parameters were measured by CT, and the individual screw placement scheme was established. It can effectively reduce the incidence of unnecessary postoperative complications caused by misplacement.
