摘　　要：目的研究椎体生理性旋转与个体发育之间的关系。方法以150例因肺部或纵隔内疾病在我院行胸部CT检查的被证实无脊柱侧凸畸形的患者的CT图像为研究对象。分三个组,各50例,幼儿组年龄为0~3岁,少儿年组为3~11岁,青年组为11~16岁。各组男女比例为1/1。椎体旋转角度的测量采用HO等人提出的角平分线法进行测量。分别对各个年龄组T2~12椎体旋转度进行测量。结果幼儿组椎体旋转角度为(-1.24±1.80)°^(1.72±1.01)°。少儿组椎体旋转角度为(-1.38±0.97)°^(1.18±1.36)°。青年组椎体旋转角度为(-1.52±1.23)°^(2.03±1.22)°。在T6节段幼儿组旋转角度明显大于少年组(P<0.01),在T7节段少年组旋转角度明显小于青年组(P=0.03)其余之间未见明显差别。结论正常人椎体存在一定程度的生理性旋转。椎体的旋转角度随年龄的增长而加剧,到达成年后椎体旋转角度趋于稳定。Objective To explore the relationship between the physiological rotation of vertebral body and individual development by measuring of rotation angle of normal spine.Methods Pectoral CT data from 150 cases without clinical or radiologic evidence of scoliosis were used to measure vertebral axial rotation from T2 to T12.The data were divided into 3 groups based on different ages： infants（0~3y）,juvenile（3~11y） and young（11-16y）.The angle,defined between two lines that connected the junction of each lamina and the pedicle of the posterior junction of the two laminae,was firstly bisected by the third line.The angle of axial vertebral rotation was then measured as the angle between the obtained line and the reference sagittal plane.The reference sagittal line was defined as zero degrees rotation.Rotation to the right was defined as a positive angle,to the left as a negative angle.Results The average rotation angle ranged from（-1.24±1.80）° to（1.72±1.01）° in group infants,（-1.38±0.97）° to（1.18±1.36）° in group juvenile,and（-1.52±1.23）° to（2.03±1.22）° in group young.The rotation angle in group juvenile significantly less than that of group infants on T6（P0.01）,and that of group juvenile significantly less than that of group youny on T7（P=0.03）.Conclusions It is revealed that the physiological rotation of vertebral occurred for the normal and nonscoliotic spine,and tends to be stable with the age increasing.
