A forearm X-ray is a scan that shows the bones between your elbow and wrist.
Your doctor may request it after a fall, direct blow, road accident, swelling, or pain in the arm. It helps check whether the radius or ulna is broken or out of alignment.
Common Indications for Forearm X-Ray
- Pain after a fall or direct injury
- Swelling, bruising, or deformity in the forearm
- Suspected fracture
- Difficulty turning the hand or moving the wrist
- Follow-up after a known fracture
- Checking bone alignment after treatment
What exactly does a forearm X-ray show?
It shows the radius and ulna, which are the two forearm bones. It can show fractures, bending injuries, dislocation near the wrist or elbow, and healing after treatment.
How should I prepare for a forearm X-ray?
You do not need to fast. Wear clothing that allows the arm to be exposed easily. Remove watches, bracelets, bangles, or metal objects near the forearm.
Do I need to stop taking medication?
No. Keep taking your usual medication unless your referring doctor tells you otherwise.
What happens when I arrive for my scan?
The radiographer will confirm which forearm is being scanned and ask where the pain is. If your arm is in a splint, the team will position it carefully.
How is the procedure performed?
You will usually sit beside the X-ray table with your arm placed on the detector. The radiographer will take images from the front and side, often including the wrist and elbow.
How long does a forearm X-ray take?
The scan usually takes about 10 to 15 minutes. It may take longer if movement is painful.
Is there any discomfort?
No. The X-ray itself is painless. Moving an injured forearm into position may hurt briefly.
Are there risks?
A forearm X-ray uses a small amount of radiation. No radiation stays in your body after the scan. The team only takes the views needed.
Can children have this scan?
Yes. Children can have a forearm X-ray when needed, especially after falls. The radiographer adjusts the technique for the child's size.
Can I have this scan if I am pregnant?
Pregnancy Precaution
Tell your doctor or radiographer if you are pregnant or think you might be. The forearm is far from the womb, but the team still needs to know before any X-ray.
When will I get my results?
A radiologist will review the images and send a report to your referring doctor. Urgent injury results may be handled faster.
What if the scan finds something?
Your referring doctor will explain the result and what happens next. You may need a cast, splint, pain treatment, or orthopaedic review.
What can this X-ray miss?
Plain X-rays show bone and alignment well but may miss a small, non-displaced, stress, or early fracture. They also provide limited information about cartilage, tendons, ligaments, nerves, and other soft tissues. Persistent focal pain, inability to use the limb, or worsening symptoms after a normal X-ray needs clinical reassessment; repeat X-rays, CT, MRI, or ultrasound may be appropriate.
Seek urgent care rather than waiting for a routine report if there is an open wound over a suspected fracture, severe deformity, rapidly increasing swelling, loss of feeling or movement, or a limb that becomes pale, blue, or cold.

Conclusion
A forearm X-ray is a quick way to check injury and bone alignment in the arm. To make the visit smoother, keep any splint or sling with you and tell the team where it hurts most.
