How It Is Done

An extremity X-ray is taken by a radiology technologist. The X-ray pictures are usually read by a doctor who specializes in interpreting X-rays (radiologist). Some other types of doctors can also review extremity X-ray pictures for common problems, such as fractures or arthritis.

You will need to remove any jewelry that may be in the way of the X-ray picture. You may need to take off some of your clothes, depending on which area is examined. You will be given a cloth or paper gown to use during the test. You may be allowed to keep on your underwear if it does not get in the way of the test.

During the X-ray test, you will sit by or be on an X-ray table with a film holder under the affected limb. The X-ray technologist will position your limb. If you have an injury, your leg or arm will be handled gently and supported when moved or repositioned. Pillows, sandbags, or other objects may be used to hold the injured limb in place while the pictures are taken. If you are wearing a brace or other device, it may need to be removed. A lead shield may be placed over your pelvic area to protect it from radiation.

Two or more pictures of the affected limb are usually taken. The test focuses on the specific area that is injured or damaged.

X-ray pictures may also be taken of joints or limbs other than those where the obvious injury has occurred, since an injury at one point may cause damage somewhere else. For example, X-rays of the thighbone (femur) may include pictures of both the knee and hip joints.

Sometimes an X-ray picture of the unaffected limb is taken so it can be compared with the affected limb. This may happen with children because their bones are still growing. In children, there is an area called a growth plate where new bone is forming. Because it can be difficult to see fractures or other changes in the growth plate, it is helpful to compare the affected limb to the unaffected limb.

An extremity X-ray usually takes about 5 to 10 minutes. You will wait about 5 minutes until the X-rays are processed in case repeat pictures need to be taken. In some clinics and hospitals, X-ray pictures can be shown immediately on a computer screen (digitally).
