上海地区208名儿童颈椎骨成熟度的研究

初步建立上海地区儿童颈椎发育标准值，为正畸的临床诊断，治疗提供有效的评定骨龄的参考指标。方法通过对Ｘ线头颅侧位定片的测量，分析上海地区２０８名１１－１５岁儿童的Ｃ２－Ｃ５颈椎体生长发育的状态及其相互关系，观察颈椎发育的形态变化规律。结果 Ｃ２－Ｃ５颈椎骨前，后缘高度及面积随年龄增长逐步递增，颈椎形态呈规律性变化，女性比男性约早熟２年，但形态变化无性别差异。

Study on the maturation of cervical vertebra for 208 cases Shanghai adolescents growth

Objective To establish a set of normal values of maturation stages of cervical vertebra for Shanghai adolescents and to provide valid reference index for assessing skeletal age while making diagnosis and treatment plan. Methods 208 Shanghai adolescents from 11 to 15 years of age were investigated by lateral cephalometric radiographs. The growth status and the relationship of C2-C5 cervical vertebra were observed. Results The anterior and posterior vertical heights and areas of C2-C5 cervical vertebra increased progressively along with the age, the shapes of cervical vertebra bodies varied regularly. Although female goes into the young quick growing period 2 years earlier than male, the shape changes have no difference between gender. The established standard values of maturation stages of cervical vertebra for Shanghai 11-15 years old adolescents revealed that the growth and development of Shanghai adolescents are getting earlier when comparing with that of GuangDong province. Conclusion The morphological variation of cervical vertebra can be used as an indicator of skeletal age to determine adolescents' growth and development status.
