How can you tell the difference between an ankle sprain and a fracture?

Ankle sprains and fractures share similar symptoms, making them difficult to distinguish. However, key differences can help you tell them apart:

Fractures typically cause severe, sharp pain directly over the bone, significant swelling, visible deformity, and an inability to bear weight on the affected foot.
Sprains usually involve pain around the soft tissue, mild to moderate swelling, bruising, and often allow some limited movement or weight-bearing.

If you're unsure whether your ankle injury is a sprain or fracture, don't guess—get clarity fast. Take a free, instant, online symptom check to better understand your symptoms and confidently navigate your next steps, whether that's rest at home or seeking urgent care.

Explanation

When you hurt your ankle, it can either be a sprain or a fracture. Sprains happen when the ankle ligaments are stretched or torn. Fractures mean there's a break in one or more of the ankle bones. Knowing the difference is important because they need different treatments.

Here are some signs to look for:

Pain and Swelling: Fractures usually cause more intense pain and swelling than sprains.
Ability to Move: With a sprain, you might still be able to move your ankle a bit, even if it hurts. Fractures often make it very hard to move your ankle or put weight on it.
Bruising and Deformity: Severe bruising or a change in the shape of the ankle might suggest a fracture.

According to studies, ankle fractures are sometimes mistaken for sprains, which can delay proper treatment. If you can't walk or your ankle looks very swollen or bruised, it's a good idea to see a doctor. You can also use Ubie's free AI-powered symptom checker to help understand your symptoms before your appointment. They might need to take an X-ray to know for sure if it's a fracture or a sprain.
