【摘要】：目的:按下颈椎椎弓根置钉方法(局部解剖定位法)的参数在计算机工作站上对C3、C4、C5椎弓根进行影像学测量,并与解剖学测定的参数进行比对、分析,以期为进一步的软件开发提供理论依据和数据库。方法:选取我院2014年10月-2016年10月在骨科住院的颈椎CT检查资料,共40例,并在计算机工作站上进行三维重建,其中男性20例,女性20例,年龄在18-70岁,平均46.98±14.10岁,排除颈椎椎弓根畸形、破坏(外伤、感染、肿瘤侵蚀)的患者。按照下颈椎C3-C5椎弓根置钉方法(局部解剖定位法)的参考系选择进钉点,在工作站测量C3-C5椎弓根最狭窄处高度(PH)、椎弓根最狭窄处宽度(PW)、在水平面上与“峡部”的后外侧面形成的横向角(E)、在矢状面上与“峡部”后侧面形成的纵向角(F),并与解剖学测定的参数进行比对、分析,使用SPSS软件对所得数据进行统计分析。结果:1.同一节段,椎弓根高度(PH)大于宽度(PW),经t检验有差异性(P0.05)。2.C3-C5椎弓根高度(PH)、宽度(PW),同性左、右侧间差异不显著P0.05,通过对比发现男性女性,经t检验有差异性(P0.05),且工作站测量的数据与解剖学研究的数据之间也存在差异(P0.05)。3.C3-C5椎弓根横向角(E)、纵向角(F),同一节段左、右侧之间、性别之间比较差异不显著(P0.05);男性椎弓根横向角(E)、纵向角(F)与女性的数值近似,且工作站测量的数据与解剖学研究的数据之间的差异亦不显著(P0.05)。结论:1.C3、C4、C5椎弓根在固定的参考系、进钉点的情况下,横向角(E)、纵向角(F)是相对不变的,表明在解剖学研究的基础上提出的下颈椎椎弓根置钉方法(局部解剖定位法)确实可行。2.数字影像辅助技术(CT工作站)可使椎弓根数据达到个性化要求。
[Abstract]:Objective: to measure C3C4C5 pedicle in computer workstation according to the parameters of pedicle screw insertion (local anatomic localization), and to compare and analyze the parameters of C3C4C5 pedicle. In order to provide theoretical basis and database for further software development. Methods: a total of 40 cases of cervical spine CT were selected from Oct 2014 to Oct 2016 in our hospital, and were reconstructed on computer workstation. There were 20 males and 20 females, aged 18-70 years, with an average of 46.98 卤14.10 years old. Exclusion of cervical pedicle malformation, destruction (trauma, infection, tumor erosion) patients. According to the reference system of lower cervical C3-C5 pedicle screw insertion (local anatomical localization), the point of insertion was selected. The height of C3-C5 pedicle at the narrowest point, the width of (PW), at the narrowest part of the pedicle, and the transverse angle (E), formed on the horizontal plane with the posterior lateral side of the isthmus on the sagittal plane and the longitudinal angle (F), formed on the posterior side of the isthmus were measured at the workstation. Compared with anatomical parameters, Analysis, the use of SPSS software for statistical analysis of the data. The result is 1: 1. In the same segment, (PH) of pedicle height was larger than width (PW), by t test (P0.05). 2.The width of (PW), of pedicle height of C3-C5 was the same as that of left, but there was no significant difference between right side and left side (P 0.05). T test showed difference (P0.05), and there was also difference between the data measured by workstation and anatomical study data (P0.05) .3.C3-C5 pedicle transverse angle (E), longitudinal angle (F), of the same segment between left and right. There was no significant difference between male and female (P0.05); male pedicle transverse angle (E), longitudinal angle (F) was similar to that of female, and the difference between workstation data and anatomical data was not significant (P0.05). Conclusion 1. The lateral angle of (E), longitudinal angle (F) is relatively unchanged when the pedicle of C _ 3 C _ 4 C _ 5 pedicle is fixed in the reference system and the point of insertion, which indicates that the method of pedicle screw insertion (local anatomical orientation method) proposed on the basis of anatomical study is feasible. Digital image aided technology (CT workstation) can make pedicle data personalized.
