An ankle X-ray is a scan that shows the bones and alignment of your ankle.
Your doctor may request it after a twist, fall, sports injury, swelling, or pain when you try to stand. It is often the first test used to check for a fracture or dislocation.
Common Indications for Ankle X-Ray
- Ankle pain after a twist or fall
- Swelling, bruising, or tenderness around the ankle
- Difficulty standing or walking
- Suspected fracture or dislocation
- Follow-up after a known fracture
- Ongoing ankle pain or arthritis symptoms
What exactly does an ankle X-ray show?
It shows the lower ends of the leg bones, the ankle joint, and the alignment of the bones. It can show fractures, dislocation, joint widening, and some long-term wear.
How should I prepare for an ankle X-ray?
You do not need to fast. Wear footwear that is easy to remove. You may need to remove socks, anklets, bandages, or metal objects around the ankle.
Do I need to stop taking medication?
No. Keep taking your regular medication unless your referring doctor tells you otherwise.
What happens when I arrive for my scan?
The radiographer will confirm the ankle being scanned and ask about the painful area. If you are in a splint or bandage, the team will decide whether it should stay on.
How is the procedure performed?
You may sit, lie down, or stand depending on the views needed. The radiographer will position your ankle on the detector and take images from different angles.
How long does an ankle X-ray take?
The scan usually takes about 10 to 15 minutes. It may take a little longer if standing views or extra images are needed.
Is there any discomfort?
No. The X-ray itself is painless. If your ankle is injured, moving it into position may hurt briefly.
Are there risks?
An ankle X-ray uses a small amount of radiation. No radiation stays in your body after the scan. The benefit of checking a possible fracture usually outweighs the small risk.
Can children have this scan?
Yes. Children can have an ankle X-ray when it is needed. 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 ankle is far from the womb, but the team still needs to know so the scan can be planned safely.
When will I get my results?
A radiologist will review the images and send a report to your referring doctor. If the injury is urgent, the centre may alert your doctor quickly.
What if the scan finds something?
Your referring doctor will explain the result and the next step. This may be rest, a cast, a brace, treatment for pain, or review by an orthopaedic team.
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 ankle X-ray is a fast way to check ankle injury and alignment. To make the visit smoother, tell the radiographer where the pain is worst before they position your foot.
