上海地区女性少年儿童颈椎骨骨龄的测量分析

Establishment of cervical vertebral skeletal maturation of female children in Shanghai

目的:建立并探讨上海地区女性少年儿童颈椎骨龄的测量方法。方法:选择上海地区240名8～15岁女性少年儿童X线头颅侧位定位片,参考Mito的颈椎骨龄测量计算法,对第三、四颈椎体各测量项目进行测量分析,应用SPSS15.0软件包计算各个年龄组测量项目的均数和标准差,采用独立样本t检验比较相邻2组测量结果的差异,并采用多元逐步回归分析得出颈椎骨龄计算方法。结果:第三、四颈椎体各测量项目随年龄的变化规律与Hassel等的形态学研究基本一致;建立的颈椎骨龄计算回归方程为Y=-5.696+8.010AH3/AP3+6.654AH3/H3+6.045AH4/PH4(r=0.912)。结论:应用本研究建立的方法计算出的颈椎骨龄,可作为上海地区女性少年儿童颌面部生长发育的评价指标。

PURPOSE： To establish a method for quantitatively evaluating skeletal maturation of cervical vertebrae of female children in Shanghai. METHODS： The samples were selected from lateral cephalometric radiographs of 240 Shanghai girls, aged 8 to 15 years. The parameters were measured to indicate the morphological changes of the third （ C3 ） and fourth （ C4 ） vertebrae in width, height and the depth of the inferior curvature. The independent-sample t test and stepwise multiple regression analysis were used to estimate the growth status and the ratios of C3, C4 cervical vertebrae by SPSS 15.0 software package. RESULTS： The physical and morphological contour of C3, C4 cervical vertebrae increased proportionately with the increment of age. The regression formula for indicating cervical vertebral skeletal age of female children in Shanghai was expressed by the equation Y=-5.696＋8.010 AH3/AP3＋6.654 AH3/H3＋6.045AH4/PH4 （r= 0,912）. CONCLUSION： The regression formula resulted from morphological measurements quantitatively indicates the skeletal maturation of cervical vertebrae of female children in Shanghai.
