摘　　要：目的观察东莞市男性青少年手腕骨发育特点。方法收集东莞市263名15~20岁正常男性青少年手腕正位X线片,根据RUS-CHN手腕骨成熟度标准评估样本骨龄。结果(1)尺、桡骨远端分别于16~18.5、16~19岁闭合;(2)第一掌骨近端于>16.5岁全部闭合,第三、五掌骨于>17.5岁全部闭合;(3)近节、中节指骨于>17.5岁全部闭合;(4)第一远节指骨于>16岁全部闭合,第三、五远节指骨于>17~17.5岁全部闭合;(5)RUS-CHN骨龄与生活年龄呈中度相关(Pearson相关系数0.585~0.781,P<0.01)。结论东莞市男性青少年尺桡骨远端及掌指骨完全闭合时间较国内其他报道提前,手腕骨发育存在一定程度的个体差异。Objective To observe the skeletal development characteristics of hand and wrist in Dongguan male adolescents.Methods Plain radiographs of hand and wrist were collected from 263 healthy male adolescents aged 15-20 years in Dongguan city.The skeletal ages were evaluated using RUS-CHN wrist bone maturity standard.Results The closure ages were 16-18.5 years in distal radius,16-19 years in distal ulna,>16.5 years in the first proximal metacarpus,>17.5 years in the third and fifth metacarpi and proximal and middle phalanges,>16 years in the first distal phalanx,and>17-17.5 years in the third and fifth distal phalanxes.The skeletal age of RUS-CHN was moderately correlated with life age(r=0.585-0.781,P<0.01).Conclusion The complete closure time of distal radius/ulna,metacarpi and phalanges in Dongguan male adolescents is earlier than that of other Chinese reports.There are individual differences in skeletal development of hand and wrist.
