Epiphyseal union of the anterior iliac crest and the medial clavicle is examined in 605 males and 254 females in a sample of modern Americans aged 11-40 years. The sample includes American whites, American blacks, Latin-Americans, and Orientals. This is the first skeletal investigation using a large sample of individuals of known age since the McKern and Stewart study of 1957. Epiphyseal union is analyzed in terms of four stages: 1) nonunion with no epiphyses, 2) nonunion with separate epiphyses, 3) partial union, and 4) complete union. The results provide broader age ranges for the stages of union than previous studies. Age ranges for males and females are similar or vary by only 1-2 years. Racially, no major distinguishing patterns are found except for greater variability in age distributions appearing to exist among American black females. The study furnishes valuable data on epiphyseal timing in the teenage years.
对605名男性和254名女性（年龄在11至40岁之间的现代美国人样本）的髂前嵴和内侧锁骨的骨骺愈合情况进行了检查。该样本包括美国白人、美国黑人、拉丁裔和东方人。这是自1957年麦肯和斯图尔特研究以来首次使用大量已知年龄个体样本进行的骨骼调查。骨骺愈合情况根据四个阶段进行分析：1）无骨骺的未愈合，2）骨骺分离的未愈合，3）部分愈合，4）完全愈合。结果显示，与以往研究相比，愈合阶段的年龄范围更广。男性和女性的年龄范围相似，或仅相差1至2岁。在种族方面，除了美国黑人女性的年龄分布似乎存在更大的变异性外，未发现主要的区别模式。该研究提供了关于青少年骨骺愈合时间的宝贵数据。
