对289名健康人的腰椎正侧位X线片上的腰椎间隙,椎体和腰长进行观测,结果腰椎间隙男女性自上而不逐渐增大,其中3.4.5椎间隙较大,3.5相似,以第4椎间隙最大,而男性均大于女性L_4中与L_3中,L_5中与 L_4中(P>0.05)L_5前与L_4前(P<0.05)以外,均有显著性差异(P<0.01);1椎体高度男女性自上而下逐渐增大,男性均大于女性(P<0.01)男女性L_1-L_3后高大于前高,L_4至L_5前高大于后高(P<0.01);腰长,男性平均212.00(±11.99)毫米,女性196.70(±14.73)毫米,男女之比P<0.01。另外,文中还对各平均值的95％正常值范围进行了估计。
289 healthy people’s lumbar posterior lateral radiographs on the lumbar intervertebral space, vertebral body and waist length were observed, the results of the lumbar intervertebral space men and women gradually increased from the top, of which 3.4.5 intervertebral space larger, 3.5 similar, The intervertebral space was the largest in the fourth intervertebral space, but was significantly higher in males than in L_4 and L_3, L_5 and L_4 (P> 0.05) L_5 and before L_4 (P <0.05) (P <0.01). The height of male and female L_1-L_3 was higher than that of the former, and the height before L_4 to L_5 was higher than that of the latter (P <0.01). The height of lumbar The average length was 212.00 (± 11.99) mm for males and 196.70 (± 14.73) mm for females, with a P <0.01. In addition, the average value of 95% of the normal range were also estimated.
