目的:探讨Mimics 软件分析新型复合型颈椎前路内固定方式——下颈椎前路椎弓根螺钉(anterior transpedicular screw,ATPS)固定+零切迹内固定方式的可行性。
方法:选取2021年1月至2022年9月50例行颈椎CT扫描的正常人行C1-C7节段扫描,其中男27例,女23例,年龄25~65(46.0 ± 9.0)岁。导出Dicom 格式,刻入光盘,通过Mimics软件对各节段进行三维重建。并在图像上置入模拟螺钉,按照零切迹螺钉的临界值(头尾倾角44°,内倾角29°)置入,观察每个节段零切迹螺钉所在位置,确定下颈椎前路椎弓根螺钉固定+零切迹内固定方式的可行性。
结果:在本次研究中,对于上位零切迹螺钉,50例研究对象的颈椎三维图像在C3-C7节段中均处于安全位置中,且没有出现上位零切迹螺钉与ATPS螺钉相交。对于下位零切迹螺钉,在C3-C4、C4-C5中,50 例研究对象的颈椎三维图像中有4例处于安全位置,46例在最大尾倾角分别为(32.3±1.9)°和(36.1±2.2)°时可实现安全置钉;在C5-C6、C6-C7 2个节段中,没有出现下位零切迹螺钉与ATPS螺钉相交,螺钉均处于安全位置。
结论:下颈椎前路椎弓根螺钉固定+零切迹内固定方式通过选择的进钉点、位置可以实现置钉成功。 |

Abstract:
Objective To investigate the feasibility of mimics software in analyzing a new type of complex anterior cervical fixation——anterior transpedicular screw fixation+zero notch internal fixation.
Methods From January 2021 to September 2022,50 normal pedestrians who underwent cervical spine CT scanning were selected for C1-C7 segment scanning,including 27 males and 23 females,aged from 25 to 65 years old with an average of (46.0 ± 9.0) years old. The dicom format is exported and engraved into the CD,and use the mimics software to perform 3D reconstruction of each segment. A simulated screw is placed on the image according to the critical value of zero notch screw (head and tail angle 44°,internal angle 29°). The position of zero notch screw in each segment is observed to determine the feasibility of anterior transpedicular screw fixation plus zero notch internal fixation.
Results For the upper zero notch screws the three-dimensional images of the cervical spine across all 50 subjects within the C3-C7 segments demonstrated safe position,with no instances of intersection with ATPS. For the lower zero notch screw,in C3-C4 and C4-C5,4 out of 50 subjects are in the safe position in the three-dimensional images of cervical vertebrae,and 46 cases could achieve secure screw placement when the maximum caudal angle is(32.3±1.9) ° and (36.1±2.2) °,respectively. In C5-C6 and C6-C7 segments,no lower zero notch screws intersected with ATPS,and all screws are in safe positions.
Conclusion Lower cervical anterior pedicle screw fixation plus zero notch internal fixation can achieve successful nail placement through the selected entry point and position. |
