高原青少年上肢骨骨龄与生长的相关性研究

THE RELATIVE STUDY ON THE BONE AGE AND ITS GROWTH IN JUVENILE UPPER LIMB BONE AT PLATEAU

目的 探讨高原青少年上肢骨骨龄与生长的关系 ,骨龄与青春期身高突的关系 ,第一掌指关节内侧种籽骨和末排指骨干骺愈合、尺、桡骨骺愈合关系。方法 世居青藏高原 (海拔 30 0 0～ 4 0 0 0米 ) 7～ 18周岁 732名健康汉族男、女学生上肢骨X光片观察。结果 上肢骨不同部位骨化中心出现男女有差别 ,愈合率不同。讨论 对高原地区的骨龄进行分析 ,比较 ,因受到高寒、低压、缺氧和生活条件的影响 。

Objective To explore the relationship between the bone age of upper Limb bone and its growth;the bone age of the body height;the first metacarpophalangeal sesamoid cartilage and Last phalanges epithysis ulna and radius healing Method Observing the roentgenogram of the upper limb bone of 732male and famale Han students of 7 to 18 years old live in Qinghai-Tibetan altitude(above sea level 3,000-4,000meters) Results The ossification center in different parts of upper limb shows different between males and femmles and same as in healing Conclusion Affected by cold,hypobavic hypoxia and life condition,the growth of youngth in altitude is slower than those in plain
