腰椎骶化者腰椎矢状曲度的测量及研究

目的测量腰椎骶化者及正常人的腰椎矢状曲度,探讨腰骶部移行椎更具临床意义的分型。方法根据Castellvi分型方法选出Ⅰ型37例(A组),Ⅱ、Ⅲ及Ⅳ型45例(B组),正常人50例(C组),在腰椎侧位片上测量腰椎前凸角(lumbar lordosis angle,LLA)、骶骨水平角(sacrum horizontal an-gle,SHA)、腰骶角(lumbosacral angle,LSA)和腰椎曲线指数(lumbar curvature index,LCI),并对三组间各参数进行统计学比较分析。结果 B组与A组LLA、SHA和LCI比较,差异有统计学意义(P<0.05);C组与B组LLA、SHA及LCI比较,差异亦有统计学差异(P<0.05);但A组与C组各参数值比较无统计学差异(P>0.05)。LSA在三组间相比较亦无统计学差异(P>0.05)。结论 Castellvi分型中Ⅰ型无具体临床意义,并提出新的分型供参考。

The Measurement and Research on Lumbar Sagittal Curvature of the Lumbar Sacralization

Objective To determine the lumbar sagittal curvature and to explore the new classification on lumbosacral transitional vertebra of the sacralization and normal men. Methods According to Castellvi classifica- tion, 37 cases of Castellvi type Ⅰ （group A）, 45 cases of Castellvi type II, Ⅲ and IV （group B）, and 50 cases of nor- real adults （group C） were selected to research. The lumbar lordosis angle （LLA）, sacral horizontal angle （SHA）, lumbosacral angle （ISA） and lumbar curvature index （LCI） were measured on the lateral radiograph film. The vari- ous parameters were compared among three groups. Results There was significantly difference on LLA,SHA,LCI between group B and group A （P 〈 0.05）, or between group B and group C （P 〈 0. 05）, but no statistic difference between group A and group C （P 〉 0. 05 ）. LSA has no remarkable difference among three groups （P 〉 0.05）. Conclusions The typeIof Castellvi has not clinical significance. New classification might be put forward to reference.
