学龄时期是在婴幼儿发育的基础上经历着人体生长发育第二个高峰向成年人迈进的阶段。深入研究学龄儿童机体各个方面的发育水平及其特征、揭示它们的内在联系实有必要。评价人体骨骼发育的部位是多方面的,但从国内外研究所见,最常用的是分析拍照手腕骨X光片的办法,以此代表整体骨发育水平。同时,许多资料常常是把骨龄研究同其它生长发育指标(如身高、体重、性发育等)有机的结合起来,解答了一些未知数。鉴于学龄儿童手腕骨发育水平按不同性别年龄有其形态特征,为了更具体更简便地评价儿童骨骼发育,比较确切而又直观地判定学龄儿童骨龄,我们于1981年对
The school-age period is the stage of developing the second peak of growth and development to the adult based on the development of infants and young children. In-depth study of the development of school-age children in all aspects of the level and characteristics of the body, revealing their intrinsic link is necessary. Evaluation of the human body parts of the development of bones are many, but from domestic and foreign studies have seen the most commonly used method is to analyze photographs of wrist X-ray film, in order to represent the overall level of bone development. In the meantime, many of the data are often organically combined with bone growth studies (such as height, weight, sexual development, etc.) to answer some unknown data. In view of the fact that the developmental level of wrist bones of school-age children has its morphological characteristics according to different gender and age, in order to evaluate the bone development of children more specifically and more conveniently and to determine the bone age of school-age children more accurately and intuitively,
