观察了11～15岁的37名体格发育先进少年手腕骨发育状况。结果表明，高身材者绝大多数（32例）骨龄不同程度地高于时间年龄，其中有8人骨龄大于时间年龄2岁以上，各年龄男性骨龄超值均大于女性。采用克托莱指数划分体型，有近40％的观察对象列为粗壮型，无论在男性、女性，都呈现出粗壮型骨龄均值明显大于适中型。被检者Ⅱ掌骨长度明显高于国内对普通儿童少年人群检测的发育水平，Ⅱ掌骨指数均值多数年龄处于9．0以上，且女性此值较高，提示在青春发育初期，采用Ⅱ掌骨长度或指数预测儿童未来身高具有一定价值。
Thirty-seven advanced physical development teenagers were studied for bone development at 11-15 years old. The results showed that the majority of tall people (32 cases) had higher bone age than those of time, of which 8 were older than 2 years old. The age of men was higher than that of women in all age groups. Using the Ketolai index divided body type, nearly 40% of the subjects were classified as thick type, both in males and females, showed a thick average age was significantly larger than the moderate bone age. The length of the metacarpal Ⅱ Ⅱ was significantly higher than the detection rate of common children and adolescents in China. The average age of the metacarpal II was 9.0 or above, and the higher in female, suggesting that in the early stage of puberty, Index predicts children’s future height has a certain value.
