摘　　要：目的：观察脊柱侧弯合并骨嵴患者骨嵴的解剖形态。方法：收集行西门子双源64排CT检查的脊柱侧弯合并骨嵴患者63人，将其原始数据输入西门子工作站行三维重建后处理，在横轴位、矢状位分别测量骨嵴的前端、中部、后端径线，观察记录其形态。结果：共发现79个骨嵴，按骨嵴分叉与否可将骨嵴分为不分叉的规则型及分叉的不规则型，规则型65个，不规则型14个，差异有统计学意义，规则型多于不规则型；规则型有多种形态，在胸腰段形态为前后粗，中间细且前端径线大于后端径线型多于其他形态，差异有统计学意义，不规则型多为后方分又型，总共14个不规则型中有7个位于第l腰椎节段。结论：骨嵴形态多种多样，在胸腰段其前端较粗，预示手术复杂程度较高。分叉型骨嵴多位于第1腰椎节段，对该节段骨嵴手术时要注意分叉情况。To observe the morphology of the osseous septum combined with scoliosis. Methods： 63 patients with osseous septum underwent Siemens dual-source 64 rows CT scanning. The data were transferred into the Siemens worksta- tion. And three-dimensional reconstruction was fulfilled. The diameters of the anterior, middle and posterior parts of the osseous septum were measured on axial view and sagittal view. The data of morphology were recorded and analyzed. Results： 79 osseous septa were found. The osseous septa were classified into two types as irregular type and regular type according to bifurcation or not. 65 septa without bifurcation were of regular type. The other 14 were irregular. The number of regular septa was more than that of irregular type. The difference was of statistical significance. The morphology of regular septa was various. The morphology of most of the septa at thoracolumbar segments was thick at the ends and thin at the center, and the diameter of the anterior end was bigger than that of the posterior end. The difference was of statistical significance. Most of the bifurcations of the irregular septa were at the posterior end. 7 of the 14 irregular septa were at the first lumbar segment. Conclusion： The morphology of the osseous septa is various. The diameter of the anterior end is always big at the- racolumbar segments, which indicates the complication of the septum resection at these segments. Many of the osseous septa with bifurcation are at the first lumbar segment. It is recommended to pay attention to the bifurcation during operation on the osseous septa at this segment.
