OBJECTIVE
A morphological analysis of the bone structure of C2 in patients with rheumatoid arthritis in order to enhance the security of the stabilization procedures for this vertebra.
METHODS
We retrospectively analyzed 20 CT scans of the cervical spine performed in patients with rheumatoid arthritis; the following parameters were measured: spinolaminar angle, thickness and length of C2 lamina.
RESULTS
THE MEAN VALUES ARE: 5.92mm and 5.87mm for thickness of right and left laminae retrospectively, 27.75mm for right lamina length and 27.94mm for left lamina length, and 44.7º for spinolaminar angle.
CONCLUSION
The values obtained are consistent with studies in normal subjects published by other groups, with no apparent need for change in the screw placement technique. Level of Evidence IV, Case Series.
目的
对类风湿性关节炎患者的C2椎体骨结构进行形态学分析，以提高该椎体稳定手术的安全性。
方法
我们回顾性分析了20例类风湿性关节炎患者的颈椎CT扫描图像；测量了以下参数：棘突椎板角、C2椎板厚度和长度。
结果
回顾性分析得出的平均值为：右侧和左侧椎板厚度分别为5.92mm和5.87mm，右侧椎板长度为27.75mm，左侧椎板长度为27.94mm，棘突椎板角为44.7°。
结论
所得数值与其他研究团队发表的关于正常受试者的研究结果一致，在螺钉置入技术方面无明显改变的必要。证据等级IV，病例系列研究。
