Ankle injuries are a common occurrence and can often be challenging to diagnose. An Ankle X-Ray is an essential diagnostic tool that can help your doctor determine the extent of an injury and provide guidance on the best course of treatment — whether you have a sprained ankle, a broken bone, or something in between.
During an Ankle X-Ray, a small amount of radiation is used to create an image of the bone and surrounding tissue. This image can help doctors diagnose fractures, dislocations, and other abnormalities. In some cases, more advanced imaging such as a CT scan may be necessary to fully assess the injury.
Combined with a physical examination, an Ankle X-Ray helps healthcare providers make informed decisions about treatment and recovery plans.
There are various reasons why a doctor may recommend an Ankle X-Ray. The most common is to check for fractures in the bones of the ankle joint, including the medial and lateral malleoli (the bony bumps on either side of the ankle), the distal tibia, and the fibula. An X-Ray can also help diagnose sprains, dislocations, arthritis, and other conditions affecting the ligaments or cartilage in the joint.
Doctors often start with a physical examination before moving on to imaging. For example, if a fracture in both the distal fibula and tibia is suspected, a lateral view X-Ray may be ordered to confirm before recommending immobilisation or surgery.
No special preparation is usually required for an Ankle X-Ray. If you have any metal objects in your ankle joint — such as a plate or screws from a previous injury — let the technologist know before the exam, as these can interfere with the image. You may also be asked to remove jewellery or other objects that could obstruct the X-Ray, as well as your shoes and socks so the technologist has a clear view of your ankle.
The technologist will position your ankle directly under the X-Ray machine and take a series of images from different angles. The entire process usually takes less than 10 minutes. You will be asked to remain completely still during the exam to prevent blurriness, and to hold your breath briefly while each image is taken.
Once complete, you can go about your day as usual — there are no activity restrictions following an Ankle X-Ray. If you experience any pain or discomfort, follow your doctor's instructions.
Check for a broken bone
An X-Ray can quickly and easily confirm whether a bone has been broken, particularly following a sudden, severe injury to the ankle.
Evaluate joint damage
An X-Ray can help your doctor assess the extent of joint damage — for example, from arthritis or another condition causing inflammation and pain — and develop an appropriate treatment plan.
Rule out other conditions
In some cases, an Ankle X-Ray may be ordered to rule out other potential causes of symptoms, such as a blood clot or infection.
Yes — a swollen ankle can be X-Rayed. This can be helpful in determining the cause of the swelling and whether or not a bone has been broken.
Not necessarily — most ankle sprains do not require an X-Ray, as they can often be treated with rest, home remedies, and over-the-counter medication without surgery.
No — Ankle X-Rays are not harmful to your health. The amount of radiation exposure from an Ankle X-Ray is very low and poses no significant health risk.
An Ankle X-Ray usually takes less than 15 minutes, including time to position your foot and take the images.
Results are typically available within 24 to 48 hours. Your doctor will review the results and discuss them with you at your next appointment.
Yes — there is no special preparation required. You can eat and drink as normal before your appointment.
