OBJECTIVE
To analyze through tomographic studies, the morphology and dimensions of the C1-C2 vertebrae in pediatric patients, to evaluate the possibility of application of Magerl's technique in these patients, and to contribute with data for the usage of the technique in safety.
METHOD
Forty normal cervical tomographies, from patients at an age range of 24-120 months of age and from both genders, were retrospectively analyzed. Data was statistically analyzed to obtain mean value and variations of each measurement: length from the C2's pedicle to C1's lateral mass, thickness of the pedicle of C2, the attack angle of the screw at the C2 isthmus with the horizontal axis and the distance from the odontoid to the anterior arch of C1.
RESULTS
THE MEAN VALUES OBTAINED WERE: length right 30.86 mm, left 31.47 mm; thickness right 5.28 mm, left 5.26 mm; attack angle right 46.25(0) , left 44.50(0) ; distance from odontoid to anterior arch of C1 2,17 mm.
CONCLUSION
The Magerl technique, after tomographic study, seems to be a viable option to be used in pediatric patients. Level of Evidence IV, Case Series.
目的
通过断层扫描研究分析儿科患者C1-C2椎体的形态和尺寸，评估Magerl技术在这些患者中应用的可能性，并为该技术的安全使用提供数据。
方法
回顾性分析40例年龄在24至120个月之间、男女均有的正常颈椎断层扫描图像。对数据进行统计学分析，以获得各项测量的平均值和变异值：从C2椎弓根到C1侧块的长度、C2椎弓根的厚度、C2峡部螺钉与横轴的进钉角度以及齿突到C1前弓的距离。
结果
获得的平均值为：右侧长度30.86mm，左侧31.47mm；右侧厚度5.28mm，左侧5.26mm；右侧进钉角度46.25(0)，左侧44.50(0)；齿突到C1前弓的距离2.17mm。
结论
经过断层扫描研究，Magerl技术似乎是可用于儿科患者的可行选择。证据级别IV，病例系列。
