In external rotation, the greater and lesser trochanters partially or completely overlap the femoral neck and intertrochanteric region ( Fig. The most common positioning error is external rotation. In this position, the contours of both greater and lesser trochanters should be visible, increasing sensitivity in the detection of subtle destructive lesions and nondisplaced fractures. Internal rotation helps to compensate for femoral anteversion and brings the femoral neck and head–neck junction into appropriate planes relative to the beam of the x-ray. Calcium pyrophosphate deposition disease.In the absence of known trauma or suspected proximal femoral fracture, the ipsilateral hip is internally rotated approximately 15 degrees to obtain the AP view ( Fig. Leg length discrepancy - treatment indications and strategies.

But you may need to schedule a follow-up appointment to discuss the results and what treatments you might need. You may be able to review X-rays with a radiologist or doctor right away.

Stand or lie very still as the X-ray image is taken. Other X-rays may require lying down so the technician can move a specialized camera over your hip to take X-ray images. Some X-rays will require standing next to a plate-shaped tool that can produce X-ray images. Let the technician know if you have any metal implants in your body that may interfere with X-ray results.Take off any jewelry or metal accessories that may stop X-rays from producing clear images.Wear loose clothing that’s comfortable and easy to take on and off if you have to change into a gown.Here are some tips to help make the X-ray process more comfortable: You don’t need to do much to prepare for a hip X-ray. Radiology labs or clinics that specialize in imaging tests typically perform hip X-rays. This common complication of osteoarthritis appears as white lines at the surface of the cartilage.

Pieces of damaged cartilage and bone from wear and tear to the joint may also be visible on a hip X-ray as white chunks around the joint. You may also see cracks in the bone, pieces missing from the femur head, or white areas where the femur has hardened ( subchondral sclerosis). When this happens, you might feel significant pain and stiffness when you try to walk, stand, or sit.
