摘要
目的 探讨肋软骨骨化与年龄和性别的关系,为法医人类学提供数据。方法 随机选取胸廓正常健康人277例（男133例,女144例）,年龄40～70岁,平均（55.9±0.5）岁。拍摄后前位X线片,观察其肋软骨骨化情况。结果 男女第1～9肋软骨骨化率自上而下依次递减,第1肋软骨和第2肋软骨（右侧）全部骨化,第6、7肋软骨骨化率女性高于男性,第8、9肋软骨骨化率则男性高于女性;肋软骨骨化程度随着年龄的增长而增大,且男性大于女性,差异有显著性（t=2.02～3.05,P〈0.05）。结论 40岁以上健康人不论男女第1肋软骨均已骨化,这为法医判断年龄提供依据。
Objective To study the relationship of the costal cartilage ossification with age and provide data for forensic science. Methods This study included 277 healthy persons （male 133, female 144） with age range （mean） 40-70 years （55.9± 0.5）. A posteroanterior chest film was taken to observe the costal cartilage ossification. Results The ossification rate of rib cartilage from the first to the ninth was degressive in both sex. The first and the second costal cartilages of the right side were all ossified. The ossification of the sixth and seventh rib cartilages was higher in female, while the eighth and ninth were higher in male. The degree of ossification developed with the age, being more significant in the male （t = 2.02- 3.05, P〈 0.05）. Conclusion The rib cartilage ossification completes in healthy people over 40 years old, male and female, which provides an evidence for forensic determination of age.
