上海地区216例青少年年龄与颈椎骨成熟度关系的研究

Clinical survey of the association between age and maturation of cervical vertebra in 216 adolescents in Shanghai municipality

目的:探讨青少年年龄与颈椎骨成熟度间的相关性。方法:采用双盲法,对216例10～20岁青少年的X线头颅侧位定位片,采用SAS6.12统计软件分析C2～C5颈椎体生长发育的状态,与年龄间的相互关系以及性别间有无差异。结果:随着年龄增长,C2～C5颈椎骨形态呈规律性变化,女性比男性约提前2a,在11岁和12岁年龄段有统计学差异,但形态变化无性别差异。青春快速生长发育期的开始时间和高峰期时间,个体差异大。结论:用头颅侧位片观察颈椎骨的形态变化判断儿童的生长发育状态,比用年龄来判断快速生长期更为准确,是临床上简便可行的方法。

PURPOSE： To investigate the relationship between age and maturation of cervical vertebra in 216 adolescents in Shanghai municipality. METHODS： 216 adolescents from 10 to 20 years old were investigated by lateral cephalometric radiographs. The growth status and the relationship of C2-C5 cervical vertebra were evaluated by SAS 6.12 software package with Fisher＇s test. RESULTS： The shapes of cervical vertebra bodies varied in regular manner. Although female went into the young quick growing period 2 years earlier than male, the shape changes had no significant difference between gender.The beginning and the peak of the puberty spurt was with great individual diversity. CONCLUSION： The morphological variation of cervical vertebra can be used as an indicator of skeletal age to determine adolescents＇ growth and development status .
