摘 要:目的:测量并分析哈尔滨地区男性少年儿童颈椎骨形态变化特点,探讨其变化规律,为临床上判断北方地区错患者骨龄提供理论依据。方法:随机抽取240名8~15岁哈尔滨地区男性少年儿童,对其头颅定位侧位片的第三颈椎(the thirdcervical vertebrae,C3)、第四颈椎(the fourth cervical vertebrae,C4)椎体进行测量,参考Mito的颈椎骨骨龄测定法,根据年龄与椎体定量性指标的相关性,使用多元逐步回归分析法得出颈椎骨骨龄的计算方法。结果:年龄与颈椎体定量性指标具有高度相关性,并得出颈椎骨骨龄回归方程Y=-20.953-28.922×AH3/AP3+52.647×H4/AP4+12.923×AH4/PH4+26.295×tanα(4r2=0.996)。结论:哈尔滨地区男性少年儿童颈椎骨发育具有增龄性变化,通过变化规律得出的骨龄方程可用来评价个体生长发育所处阶段。Objective To measure and analyze cervical vertebral maturation of boys in Harbin using Lateral cephalometric radiograph. Methods The sample included 240 adolescent male subjects (ages 8.0-15.9 years), selected randomly from Harbin.The cervical vertebral bodies of C3 and C4 of lateral cephalogram were measured. According to the method of measurement of cervical vertebral bone age from Mito, a formula was obtained by multiple stepwise regression analysis based on the relationship of age and variation of cervical vertebrae. Results High correlation between the morphology of the bodies of C3,C4 and age was showed. The regression formula from cervical vertebral skeletal age of male children in Harbin was received, and the equation was Y=-20.953-28.922xAH3/AP3+ 52.647xH4/AP4+12.923xAH4/PH4+26.295xtana4 (r2=0.996). Conclusion Skeletal age of cervical vertebrae calculated from the regression formula could be used to estimate the stage of development of boys in Harbin, owing to the growth of cervical vertebrae chanqed with a^e.
