摘要: 目的 应用骨盆髂嵴与坐骨结节骨骺发育状况的X线影像学特征评估四川汉族青少年的生活年龄。 方法 参照TW2分级原则,结合本次研究选取的年龄跨度、骨骺发育规律,将髂嵴骨骺发育程度分为8级(0~7级),坐骨结节的骨骺发育程度分为7级(0~6级)。再根据上述分级,对691例四川汉族16~20周岁青少年骨盆X线片进行阅片,运用SPSS 19.0软件进行统计学分析,并将年龄(Y)与髂嵴(X1)、坐骨结节(X2)骨骺发育级别作多元线性回归方程。 结果 双侧髂嵴、坐骨结节骨骺发育差异无统计学意义(P>0.05),髂嵴、坐骨结节骨骺发育在两性之间差异亦无统计学意义(P>0.05)。多元回归方程为Y=15.269+0.444 X1+0.236 X2,样本回代检验表明该方程准确性较高。 结论 通过髂嵴、坐骨结节骨骺发育程度的多元回归方程进行骨龄评估,可以为四川汉族人口进行18周岁的年龄评估提供科学依据。

Abstract: Objective To estimate the chronological age of Han teenagers in Sichuan by the epiphyses development characteristics of iliac crest and ischial tuberosity in X-ray digital images. Methods According to TW2 classification principle, combining with the age range of our subjects and epiphyses development regularity, the degree of epiphyses development of iliac crest and ischial tuberosity had been divided into 8 grades (0-7) and 7 grades (0-6), respectively. Based on the degrees, the pelvic X-rays digital images of 691 samples of 16-20 aged teenagers were read and statistically analyzed by SPSS 19.0 software. The multiple linear regression equation was established by skeletal age (Y), development degree of iliac crest epiphyses (X1) and ischial tuberosity epiphyses (X2). Results There were no statistical differences between two sides of epiphyses development of iliac crest and ischial tuberosity (P>0.05). There were no statistical difference between genders (P>0.05). The re-substitution method of the samples showed that the accuracy of equation as Y=15.269+0.444 X1+0.236 X2 was high. The result of the re-substitution method showed a high accuracy of the equation. Conclusion The multiple linear regression equation could be used to identify the skeletal age for providing the scientific basis to identify the 18-year-old Han population in Sichuan.
