Pelvis x-ray

Definition

A pelvis x-ray is a picture of the bones in and around both hips. The pelvis connects the legs to the body.

How the Test is Performed

The test is done in a radiology department or in the health care provider's office by an x-ray technician.

You will lie down on the table. The pictures are then taken. You may have to move your body to other positions to provide different views.

How to Prepare for the Test

Tell the provider if you are pregnant. Remove all jewelry, especially around your belly and legs. You will wear a hospital gown.

How the Test will Feel

The x-rays are painless. Changing position may cause discomfort.

Why the Test is Performed

The x-ray is used to look for:

• Fractures

• Tumors

• Degenerative conditions of bones in the hips, pelvis, and upper legs

• Abnormal shape of your bones or joint

What Abnormal Results Mean

Abnormal results may suggest:

• Pelvic fractures

• Arthritis of the hip joint

• Tumors of the bones of the pelvis

• Sacroiliitis (inflammation of the area where the sacrum joins the ilium bone)

• Ankylosing spondylitis (abnormal stiffness of the spine and joint)

• Arthritis of the lower spine

• Abnormality of the shape of your pelvis or hip joint

Risks

Children and the fetuses of pregnant women are more sensitive to the radiation of the x-ray. A protective shield may be worn over areas not being scanned or other imaging modalities can be used.
