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 study the relationship between vertebral physiological rotation and individual development. Methods The CT images of 150 patients with idiopathic scoliosis deformity underwent chest CT examination in our hospital due to pulmonary or mediastinal diseases were studied. Divided into three groups, each 50 cases, children aged 0 to 3 years, children aged 3 to 11 years, young people aged 11 to 16 years. The ratio of male to female in each group is 1/1. Vertebral rotation angle measurement HO angle angle bisector method was used to measure. The rotational degrees of T2 ~ 12 vertebral bodies in each age group were measured respectively. Results The turning angle of pediatric group was (-1.24 ± 1.80) ° ~ (1.72 ± 1.01) °. The turning angle of pediatric group was (-1.38 ± 0.97) ° ~ (1.18 ± 1.36) °. The rotation angle of vertebral body in youth group was (-1.52 ± 1.23) ° ~ (2.03 ± 1.22) °. There was no significant difference between the young group and the young group (P = 0.03). The rotation angle in the T6 group was significantly greater than that in the juvenile group (P <0.01). Conclusion There is some degree of physiological rotation in normal vertebral body. Vertebral rotation angle increases with age and aggravate, reaching the turning point of adult vertebral body tends to be stable.
