摘　　要：目的 为临床测量股骨颈前倾角提供简易、可靠的CT检查新方法。方法 取20支成人股骨,将股骨置于CT台上,股骨纵轴与CT台纵轴平行,分别取经股骨头下缘下一个断面及股骨远端的一断面作标准平面,股骨颈纵轴为CT片上股骨颈图像的中轴。髁间轴取两髁最后缘连线,测量两轴线夹角(为新法前倾角)。并与解剖法测量的结果进行比较。结果 本方法测量值与解剖法相比,无显著差异(P>0.05)。结论 我们的方法简便,准确性高,重复性好,适合临床应用。Objective To develop a novel CT melliod to measure the anteversion angle of femur neck for clinic investigation.Methods Twenty femurs of normal adults were chosen and placed on the CT table with their longitudinal axis parallel lu (hat of the tahle.The cross section below the,inferior fringe of ihe femoral head was chosen as the typical cross section viewed as regular ellipse.The major axis of the ellipse (MAE) was drawn to represent the longitudinal axis of the femoral neck.The anleversion angle of femur neck was measured as the angle between MAK and the line drawn linking the posterior fringe of the two condylcs.The results were compared with those measured with the anatomical method.Results There was no significant difference between the measurements with the authors' method and those with the anatomical method.Conclusion Compared with other CT methods,the method we designed is simpler and relatively more accurate and worthy of clinical application.
