摘要
目的 :通过男女肋软骨骨化方式及骨化率的研究进行性别判定。方法 :随机选用临床常规胸部X线片共计 2 2 3例 (男性 1 1 0例 ,女性 1 1 3例 ) ,对第 1和第 5肋肋软骨骨化形态的性别差异应用统计学方法进行研究。结果 :经 χ2 检验 ,证明第 5肋骨化形态的性别有显著性差异 (P <0 .0 0 1 )。在同年龄组中男性第 5肋的骨化率极显著地高于女性。结论 :应用该方法可判定性别 ,正确判定率在男性样本中可达 98.31 % ,女性可达 75 %。
Objective: To determine sex through the research on ossification patterns and rates of costal cartilages in men and women. Methods: Routine chest X ray pictures (223) were collected randomly. The ossification patterns of costal cartilages of the first and fifth ribs were observed and statistically analyzed. Results: It was demonstrated by χ 2 testing that the sex differences in ossification patterns were statistically significant (P<0.01 for the first rib and P<0.001 for the fifth rib). The ossification rates in the first rib in men were much more higher than that in women in the same age groups. Conclusion: We may use this technique to determine sex, the predictive ability of which was up to 98.31% in men and 75% in women.
