This study aims to investigate the anatomical structure of the C6 pedicle and lateral mass in children aged 0-14 years using CT imaging, providing detailed insights into their growth and development.
We conducted a comprehensive measurement of C6. Measurements included width, length, and height of the pedicles, as well as the length, width, and thickness of the lateral masses, and several angular metrics. Regression analysis was performed to understand the growth trends, and statistical analyses were carried out to identify differences between age groups, genders, and sides.
In children younger than four years, the pedicle width exceeds its height, influencing the diameter of the pedicle screws. By age two to three, the pedicle height and lateral mass thickness reaches 3.0 mm, allowing for the use of 3.0 mm diameter screws. The pedicle transverse angle remains stable. Most parameters showed no significant differences between the left and right sides. Size parameters exhibited significant larger in males than females at ages 0-1, 3-7, and 10-12 years. Regression analysis revealed that the growth trends of size parameters follow cubic or polynomial curves. Most angular metrics follow cubic fitting curves without a clear trend of change with age.
This study provides a detailed analysis of the anatomical development of the C6 pedicle and lateral masses in children, offering valuable insights for pediatric cervical spine surgeries. The findings highlight the importance of considering age-specific anatomical variations when planning posterior surgical fixation, specifically at C6. It is necessary for us to perform thin-layer CT scans on children and carefully measure various indicators before surgery.
本研究旨在通过 CT 成像技术研究 0-14 岁儿童 C6 椎弓根和侧块的解剖结构，深入了解其生长发育情况。
我们对 C6 进行了全面测量。测量包括椎弓根的宽度、长度和高度，以及侧块的长度、宽度和厚度，以及几个角度参数。进行回归分析以了解生长趋势，并进行统计分析以确定年龄组、性别和侧别之间的差异。
在 4 岁以下的儿童中，椎弓根的宽度超过其高度，影响椎弓根螺钉的直径。到 2-3 岁时，椎弓根高度和侧块厚度达到 3.0mm，可以使用 3.0mm 直径的螺钉。椎弓根横角保持稳定。大多数参数在左右两侧之间没有显著差异。0-1、3-7 和 10-12 岁时，男性的尺寸参数明显大于女性。回归分析显示，尺寸参数的生长趋势遵循立方或多项式曲线。大多数角度参数遵循立方拟合曲线，没有明显的随年龄变化趋势。
本研究详细分析了儿童 C6 椎弓根和侧块的解剖发育情况，为小儿颈椎手术提供了有价值的见解。研究结果强调了在规划后路手术固定时，考虑年龄特异性解剖变异的重要性，特别是在 C6 处。对于儿童，我们需要在手术前进行薄层 CT 扫描，并仔细测量各种指标。
