摘　　要：目的:通过对髌骨轴位摄影方法的改良与设计,显示常规轴位摄影难以显示的髌骨半脱位征象并探讨该改良轴位的其它临床应用价值。方法:根据膝关节分别屈曲30°,60°,90°时水平侧位上预置的金属线与髌骨关节面所成角的测量,确定出髌骨轴位X线入射角度范围,再对40例髌骨半脱位患者实施改良髌骨轴位摄影。结果:应用髌骨改良轴位进行摄影,准确显示出髌骨半脱位征象,所有影像均达到临床诊断要求。结论:髌骨改良轴位摄影操作简单易行,成功率高,显示髌骨半脱位征象清晰准确。对髌骨半脱位、髌骨骨折的诊断和术后评估有极大的价值。Objective：To find a new method to show the subluxation of the patella that can not be displayed well by the traditional way. Methods：To measure the angel of the articular surface of the patello-femoraljoint with the wire that is parallel to the photographic bed to find the range of the angel of the x-ray tube’s centerline,then with the range of the angel ,the new axial view of patella can be taken with the supine position . Results：With this new method,the picture of the subluxation of the patella is very helpful to the clinical diagnosis. Conclusion：This new method of axial view of patella is accurate,easy to use and very useful to the diagnosis of the fracture of patella, but also useful to the estimate of the situation after operation.
