Extremity x-rays are performed in a hospital radiology department or in the health care provider's office by an x-ray technician. You will be asked to position the extremity to be x-rayed on the table. The pictures are then taken, usually with repositioning of the extremity for different views.

Inform the health care provider if you are pregnant. Remove all jewelry from the area being imaged.

In general, there is no discomfort, although you may be slightly uncomfortable while the extremity is positioned for the x-ray.

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

The x-ray shows normal structures for the age of the patient.

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

Additional conditions under which the test may be performed:

• Clubfoot
• Foreign body detection

There is low-level radiation exposure. X-rays are monitored and regulated to provide the minimum 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 an x-ray.
