摘　　要：目的:对贵州省健康儿童青少年手腕部X线片进行骨龄测评,为制定正常儿童青少年手腕部骨发育评分标准、观察骨发育的变化趋势提供依据。方法:收集贵州省960例3~18岁正常儿童青少年的左侧手腕部正位X光片,采用TW3法测定各年龄段男女性儿童及青少年骨发育分(SMS),绘制SMS趋势图,统计各年龄段男女性儿童及青少年手腕部骨骺闭合率。结果:儿童青少年手腕部骨发育分随年龄增长而增加,相同年龄段女性骨发育分大于男性骨发育分,第1掌骨的骨骺闭合年龄男女性均为14岁,第2至4掌骨及指骨骨骺闭合年龄男性为15岁,女性为14岁,各年龄组指骨闭合率按照远排、近排、中排顺序依次逐渐减低;尺桡骨干骺端闭合年龄男性为17岁,女性为16岁。结论:初步了解贵州省儿童青少年手腕部骨骺闭合年龄,女性骨发育较男性提前,为制定TW3计分法骨龄标准提供参考依据。Objective： To assess the skeletal age by using wrists X-ray pictures in children and adolescents in Guizhou and provide the basis for establishing the scoring criteria for bone development of normal children and adolescents and for observing the trend of bone development. Methods： The left wrist X-ray pictures of 960 cases of normal children aged 3 to 18 years old on were collected in Guizhou. TW3 method was used to measure bone development in male and female children and adolescents of all ages. The SMS trend map was drawn,the closed rate of wrist epiphysis in male and female children and adolescents of all ages was analyzed. Results： The wrist skeletal development in children and adolescents increased with age,and the bone development scores in females of the same age group was higher than that in males. The closure of metacarpal and phalange＇s epiphysis was at 15 years old in male and 14 years old in female; The closure of distal radius and ulna ＇s epiphysis was at 17 years old in male and 16 years old in female. Conclusion： The skeletal development of adolescents in females was earlier than males,and reference data are provided for establishment of bone age standard.
