What are Thumb X-rays?
Thumb X-rays are a common imaging test that uses small amounts of high-energy electromagnetic radiation to produce images for doctors to view the inside of the body in and around the thumb. The level of exposure is considered safe for adults. It is not considered safe for a developing fetus so it is very important that a pregnant patient informs a physician of their pregnancy before having an X-ray taken.
Thumb X-rays pass through skin and soft tissue mostly, but do not pass through bone or metal easily. As different tissues in the body absorb different amounts of radiation, the images will show different shades of black and white.
One of the most common uses of a thumb X-ray is to check for broken bones after an accident, but they are also used under many other circumstances.
Thumb X-rays are used to identify, diagnose, and treat many types of medical conditions. It is a key element and often times the first to be done in the diagnosis process.
A thumb X-ray is a safe and painless test that uses a small amount of radiation to take a picture of a patient's foot, ankle or even leg.
Reasons for a Thumb X-Ray:
Thumb X-rays are used for a multitude of reasons. A physician may order an X-ray to check for certain cancers in different parts of the thumb by detecting abnormal tumors, growths or lumps.
A thumb X-ray is used to view the area of the body where a patient is experiencing pain, swelling, or other abnormalities that require an internal view of the body. The X-ray can help a physician find a cause for the problems occurring.
Thumb X-rays can be used to diagnose a disease, monitor the progression of the disease, determine a treatment plan, and see the effect of a treatment plan.
Physicians use thumb X-rays to locate foreign objects within the body and to guide them in setting broken bones.
A Thumb X-Ray may help diagnose (find):
X-rays of the thumb are used to determine the cause of symptoms such as pain, tenderness, swelling or a deformity of the thumb, other fingers, hand or even wrist.
A thumb X-ray can detect infection, cysts, or tumors in the thumb.
A thumb X-ray can detect broken bones, assist a physician in setting the broken bone, and can monitor the treatment process to determine whether the bone is properly aligned and the break is healing properly.
Thumb X-rays are used in pre-surgical planning and are used post-surgery to assess the results of the surgery.
