摘要

目的:利用计算机断层扫描测量C6、C7椎弓根的直径和厚度,分析该手术的安全性及男女差异。方法:回顾性研究。对圣特蕾莎医院放射科的200张颈椎计算机断层扫描图进行了评估,其中100张是男性,100张是女性。在轴向面测量椎弓根厚度,矢状面测量椎弓根高度。采用学生t检验比较性别差异,p值小于0.05被认为是显著的。结果:纳入样本的个体平均年龄为35±9岁。C6和C7椎弓根平均高度分别为7.1±0.9 mm和7.8±0.9 mm。C6和C7椎弓根平均厚度分别为5.2±0.7 mm和5.9±0.8 mm。统计检验表明,女性患者的数值明显较低。结论:本研究提供的参数可作为C6和C7颈椎经椎弓根固定手术术前规划的准则。由于该手术可引起重要结构的医源性损伤,因此在术前计划中必须谨慎选择螺钉的大小,以避免血管破裂或损伤邻近神经。证据等级III;回顾性研究。

MORPHOMETRIC STUDY OF THE C6 AND C7 PEDICLE: A COMPUTERIZED TOMOGRAPHY ANALYSIS
ABSTRACT Objective: Measure the diameter and thickness of the C6 and C7 pedicles using computed tomography, to analyze the security of the act surgery and the difference between males and females. Methods: This is a retrospective study. Two hundred computerized tomography scans of the cervical spine, one hundred male and one hundred female, from the Hospital Santa Teresa Radiology sector were evaluated. The pedicle thickness was measured in the axial plane, and the height was measured in sagittal slices. The student’s t-test was used to compare differences between the sexes, and a p-value lower than 0.05 was considered significant. Results: The mean age of the individuals included in the sample was 35±9 years. The mean height of the C6 and C7 pedicles were 7.1±0.9 mm and 7.8±0.9 mm, respectively. The mean thickness of the C6 and C7 pedicles were 5.2±0.7 mm and 5.9±0.8 mm, respectively. The statistical test showed that the values were significantly lower for female patients. Conclusions: The present study demonstrated parameters that can be used and can be the rule for preoperative planning of transpedicular cervical fixation surgeries, both in C6 and C7. As it is a procedure that can cause iatrogenic damage to important structures, the screw size must be chosen with care in pre-operative planning to avoid vessel rupture or damage to adjacent nerves. Level of Evidence III; retrospective study.
