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 provide a simple and reliable new method of CT examination for clinical measurement of femoral neck anteversion. Methods Twenty adult femurs were obtained. The femur was placed on a CT table. The longitudinal axis of the femur was parallel to the longitudinal axis of the CT table. A cross-section of the lower edge of the femoral head and a distal section of the femur were taken as standard planes. Central axis of CT image on femoral neck. Intercondylar axis of the two condyles take the last edge of the line, measuring the angle between the two axes (for the new law anteversion). And compared with anatomical measurements. Results The measured value of this method compared with the anatomic method, no significant difference (P> 0.05). Conclusion Our method is simple, accurate, reproducible and suitable for clinical applications.
