Joint X-ray

Definition

A joint x-ray is an x-ray image of a joint.

How the test is performed

The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technician. You will position the joint to be x-rayed on the table, pictures are taken, and the joint is repositioned, if necessary, for different views.

How to prepare for the test

Inform the health care provider if you are pregnant. Remove all jewelry.

How the test will feel

The x-ray is not uncomfortable, except possibly from positioning the area being x-rayed.

Why the test is performed

Joint x-ray is used to detect fractures, tumors, or degenerative conditions of the joint.

What abnormal results mean

Abnormal results include arthritis, fractures, bone tumors, degenerative bone conditions, and osteomyelitis (inflammation of the bone caused by an infection).

Additional conditions under which the test may be performed:

What the risks are

There is low radiation exposure. X-rays are monitored and regulated to provide the smallest amount of radiation exposure needed to produce the image. Most experts feel that the risk is low compared with the benefits. Pregnant women and children are more sensitive to the risks of the x-ray.
