The modified Cleaves method for an AP hip projection involves flexing and abducting the patient's thighs to demonstrate the proximal femur and hip joint without foreshortening. This positioning results in the lesser trochanter being demonstrated in profile due to the rotation of the femur, and the greater trochanter appearing at a level halfway between the lesser trochanter and femoral head because of the angle of the femur with respect to the imaging plane. The ischial spine is demonstrated with pelvic brim superimposition due to the orientation of the pelvis in this projection. The greater trochanter is not specifically demonstrated medially in this method; its appearance is more related to its anatomical position relative to the lesser trochanter and femoral head as affected by the positioning.
