A radiograph of a unilateral frog-leg (modified Cleaves method) projection reveals that the femoral neck is foreshortened and distorted.The radiologist is concerned about pathology involving the neck.What can the technologist do to improve the visibility of the femoral neck without foreshortening during the repeat exposure?

Decreasing the abduction of the femur to 20° to 30° from vertical helps in reducing the foreshortening of the femoral neck, thus improving the visibility of the area of interest without distortion. This adjustment aligns the femoral neck more parallel to the direction of the X-ray beam, resulting in a more accurate representation of the femoral neck on the radiograph.
