An elbow X-ray is a scan that shows the bones and alignment of your elbow joint.
Your doctor may request it after a fall, direct blow, swelling, stiffness, or pain when bending the arm. It can help check for fractures, dislocation, and some joint problems.
Common Indications for Elbow X-Ray
- Pain after falling on the hand or elbow
- Swelling or bruising around the elbow
- Difficulty bending or straightening the arm
- Suspected fracture or dislocation
- Ongoing elbow pain or arthritis symptoms
- Follow-up after treatment for an elbow injury
What exactly does an elbow X-ray show?
It shows the lower end of the upper arm bone and the upper ends of the forearm bones. It can show fractures, dislocation, alignment problems, and some signs of joint swelling.
How should I prepare for an elbow X-ray?
You do not need to fast. Wear short sleeves or clothing that is easy to move away from the elbow. Remove bracelets, watches, or metal objects near the arm.
Do I need to stop taking medication?
No. Keep taking your regular medication unless your referring doctor gives a different instruction.
What happens when I arrive for my scan?
The radiographer will confirm which elbow is being scanned and where it hurts. If your arm is in a sling or splint, the team will decide how best to position it.
How is the procedure performed?
You will usually sit beside the X-ray table with your arm placed on the detector. The radiographer may take front, side, and angled views.
How long does an elbow X-ray take?
The scan usually takes about 10 to 15 minutes. Extra views may take a little longer.
Is there any discomfort?
No. The X-ray itself is painless. If your elbow is injured, bending or turning the arm may hurt briefly.
Are there risks?
An elbow X-ray uses a small amount of radiation. No radiation stays in your body after the scan. The benefit of checking an injury usually outweighs the small risk.
Can children have this scan?
Yes. Children often need elbow X-rays after falls. The radiographer uses settings based on 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 elbow 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 injuries may be handled faster.
What if the scan finds something?
Your referring doctor will explain the result and next step. You may need a sling, cast, pain treatment, follow-up imaging, 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
An elbow X-ray is a quick way to check pain, swelling, or injury around the elbow. To make it smoother, tell the radiographer if you cannot bend or straighten the arm.
