【摘要】 目的:观察中国儿童手腕骨发育特征,为应用国外研究成果提供参考。方法:受试者为2005年骨发育调查样本2~18岁的16035名儿童。使用TW3方法评价手腕骨成熟度,与文献中的日本、欧美儿童的数据相比较。结果:中国和日本儿童的手腕骨发育特征相似。在儿童期,中国男儿童TW3-RUS和TW-腕骨成熟度延迟于欧美儿童0.3~0.6岁,女儿童在5~10岁TW3-RUS骨发育与欧美儿童非常接近;但在男12岁、女10岁以后,中国男女儿童TW-RUS骨成熟度加速而分别提前1.1~1.6岁和1.2岁。与欧美儿童相比,中国男儿童在3~10岁、女儿童在2~5岁,TW-腕骨成熟度分别延迟0.3~0.6岁和0.2~0.4岁;在男10岁和女5岁后,中国儿童TW-腕骨成熟度加速而提前,腕骨发育成熟的年龄均提前1.4岁。结论:与1970s~1990s的欧美儿童相比,中国儿童骨发育的延迟已不明显,但是青春期TW3-RUS骨发育加速提前的程度以及腕骨发育成熟年龄的提前则更加显著。更多还原

【Abstract】 Objective The determination of skeletal maturity is an important measure for selecting sports talent. The characteristics of skeletal development of hand and wrist in Chinese children were investigated in order to compare with overseas experiences. Methods The subjects were 16035 children, aged 2～18 years. The skeletal maturity of hand and wrist of the subjects was estimated by TW3 method and was compared with that of European, European North American and Japanese children. Results In comparison with European and American children, Chinese and Japanese children showed a similar patterns of skeletal maturation. The TW3-RUS skeletal maturity of Chinese children was retarded by 0.3～0.6 year in boys at the age of 8～12 and was very close to European and American in girls at the age of 5～10. Older than 12 years of age in boys and 10 years of age in girls, the TW3-RUS skeletal maturity of Chinese children accelerated and became advanced by 1.1～1.6 years in boys, by 1.2 years in girls. As compared with European and American children, the TW3-carpal maturity delayed by 0.3～0.6 year in Chinese boys at the age of 3～10 and by 0.2～0.4 year in Chinese girls at the age of 2～5. The TW3-carpal maturation accelerated after age of 10 in boys and age of 5 in girls. The age of complete maturity in all carpals was advanced by 1.4 year in boys and girls. Conclusion As compared with European and American children in 1970s-1990s, the delay of skeletal development of hand and wrist in Chinese children was not obvious in childhood, and the extent of advanced skeletal maturity and the age of advanced complete maturity of Chinese children are more evidently.更多还原
