Abstract: Objective To design a simple and easy to operate new position radiography as same effect as the ordinary lateral position of the hip joint.Methods Using different angles for bone model radiography, the tilt angle of X-ray and the bone model were measured in order to obtain that the femoral head and neck was fully displayed.30 subjects with hip joint disease underwent routine and improved lateral radiography of the hip joint were enrolled, and the actual operations and image quality of the two methods were compared.Results The tilt angle of X-ray was 35°-45°,and the tilt angle of the bone model was 60°-70°, and the score was 3.The new lateral radiography of the hip joint was feasible,the display rate of the articular surface and joint space were 96.7%,the display rate of the femoral head and neck all were 100%,the display rate of the greater trochanter of femur was 80%,the display rate of the lesser trochanter was 100%.Conclusion The improved method of hip joint lateral position of X-ray can better show the femoral head, neck and the rest of the bone.
