【摘要】 目的探讨《中国人手腕骨发育标准-中华05》RUS-CHN法在当代少年运动员中的应用效果。方法分别采用RUS-CHN法和原骨龄标准CHN法,评价245名8~18岁不同项目少年运动员的左手腕骨骨龄。结果不同运动项目的少年运动员,RUS-CHN骨龄与生活年龄间的差异无显著性,但原标准CHN法骨龄与生活年龄之间的差值为正数(0.71~0.91岁),且差异显著(P<0.01)。与原标准CHN方法相比,新标准RUS-CHN法骨龄读数组距更细,频数分布更均匀,并减少了骨龄与生活年龄差值等于或大于2岁的少年运动员的例数。结论当代少年运动员表现出了生长发育加速的长期趋势,《中国人手腕骨发育标准-中华05》RUS-CHN法更适用于当代少年运动员。更多还原

【Abstract】 Objective To investigate the effectiveness of <The Standards of Skeletal Maturity of Hand and Wrist for Chinese-China 05> by RUS-CHN method in estimation of skeletal maturity of Chinese young athletes. Methods Two hundred and forty five young athletes, aged 8-18 years, were the subjects in this study and their radiographs were respectively estimated by China-05 RUS-CHN and CHN methods. Results In athletes involved in different sports events, the differences between skeletal ages estimated with RUS-CHN and chronological ages were not significant. However, the differences between skeletal age estimated with previous CHN and chronological ages were significant (+0.71～+0.91 years, P<0.01). As compared with the previous CHN, the RUS-CHN new standards produced lesser number of young athletes whose differences between skeletal age and chronological age were equal to or more than 2 years. Conclusions Due to the secular trend of accelerated growth and development in young athletes, the RUS-CHN method of <The Standards of Skeletal Maturity of Hand and Wrist for Chinese-China 05> are more suitable for them.更多还原
