摘　　要：目的探讨应用MSCT三维重建精确测量髋臼外展角度的新方法,为指导全髋关节置换髋臼假体个体化准确置入及术后评估提供科学依据。方法选取30具骨盆标本共60个髋臼为研究对象,以骨盆前平面为参照平面,分别应用数显角度仪及MSCT三维重建精确体位调整均值法对髋臼外展角度数值进行测量,对两种方法的测量结果进行比较。结果应用数显角度仪及MSCT三维重建精确体位调整均值法测量髋臼外展角度分别为(48.73±3.19)°和(48.65±2.47)°,两者比较无统计学差异(P>0.05),表明MSCT三维重建精确体位调整均值法测量髋臼外展角度数值结果准确,与实际测量无明显差异。结论以骨盆前平面为参照平面,MSCT三维重建精确体位调整均值法为全髋关节置换术提供一种术前准确测量髋臼外展角度数值的新方法,减少人为操作引起的误差,实现髋臼外展角度数值的标准化测量和评价。Objective ： To investigate the application of multi-slice spiral CT reconstruction accurate measurement of ace- tabular abduction angle, and to provide a scientific basis for guidance of total hip replacement aeetabular prosthesis individu- alized accurate placement and postoperative evaluation. Methods：The research objects were 60 aeetabulars of 30 pelvic spec- imens, and with anterior plane of pelvis as a reference plane, acetabular abduction angles were measured respectively by digital goniometer and multi-slice CT reconstruction with precise postural adjustment. Results：The aeetabular abduction an- gle means of 30 pelvic specimens by digital goniometer and multi-slice CT reconstruction with precise postural adjustment were （48.73± 3.19）°and （48.65 ±2. 47） ° respectively, and they had no significant difference （P 〉0.05）. These data showed that the measurement of acetabular abduction angle by multi-slice CT reconstruction with precise postural ad- justment was accurate, which had no significant difference from the actual measurement. Conclusion：Multi-slice CT recon- struction with precise postural adjustment, with the anterior plane of the pelvis as a reference plane, is a new method of a preoperative acetabular abduction angle measurement for total hip arthroplasty, which can reduce human error in operation and achieve standardized measurement and evaluation of hip acetabular abduction angle.
