X-rays
Introduction
An x-ray gives the doctor a simple, 2-dimensional picture of the bones in
the hip. The picture is generated on a piece of film by a beam of radiation
that the x-ray machine passes through the hip.
Only bones show
up on an x-ray image. The picture can tell your doctor if you have a broken
bone, bone fragments, advanced osteoarthritis, or the later stages of
avascular necrosis. However, an x-ray image doesn’t show muscles, ligaments,
tendons, and other soft tissues, so it can’t detect problems like bursitis
or the early stages of avascular necrosis.
The machine is usually
located in a room of its own, with the controls behind a window off to the
side. The procedure is painless and quick; you need to remain motionless for
only a short period of time. The procedure uses only a small amount of
radiation, so it doesn’t cause any harm.
Getting Ready For the X-ray
For hip problems, no special preparations are needed.
During the X-ray
After putting on a gown, you’ll lie down on the x-ray table. After the
technician positions your hip, he’ll gently pull the x-ray machine down,
coming close to—but not touching—your hip. He’ll ask you to hold your
position and then walk into the other room to work the controls that take
the picture. He may reposition your hip several times, depending on how many
x-rays you need.
After the X-ray
Because you don’t need any medication or injections, you can drive yourself
home afterwards, with your doctor’s permission.
Your doctor
will review the pictures and call you with the results, or review the
results with you at your next office visit.
Frequently Asked Question

necessary for your health.
