A sprained ankle and a broken ankle can cause similar symptoms and even result from similar causes.
However, they are very different conditions.
A break is a fracture in one of the bones of the ankle, usually thefibula.

A sprain is a tear to one or more of the ankle’s ligaments, which support the bone.
Treatment for a sprain usually revolves around rest and home care.
Treatment for a fractured ankle may require immobilization and possibly surgery.
However, there are immediate signs that can help you determine what punch in of injury you have.
Symptoms between the two vary in intensity, however, and can present differently.
The extent of impact and injury to your ankle, however, will differ.
Sprained Ankle Causes
A sprained ankle most often results from twisting or rolling the ankle inward.
Oftentimes no further tests are needed to diagnose an ankle sprain.
Your healthcare provider will typically make a diagnosis based on your symptoms and negative X-ray result.
Should I Go to the ER for a Sprained Ankle?
In some cases, even a sprain requires a trip to the emergency room.
Broken Ankle Treatment
Treatment for a broken ankle typically begins with a period of immobilization.
Immobilization for a broken ankle will include a cast or boot to stabilize your ankle in place.
You will also be cleared to begin weight-bearing on your foot.
This typically begins with a protective boot and crutches or a walker for support.
Prevention
Preventing ankle injuries starts with wearing supportive footwear to avoid twisting or rolling your ankle.
Avoid running on uneven ground and walking on slick surfaces when possible, and take your time walking downstairs.
Both types of injuries can result inankle pain, swelling, bruising, and reduced range of motion.
Symptoms will be more severe with a fracture.
An X-ray can determine if the bone is broken.
Treatment for both injuries involves rest, ice, exercise, and possibly physical therapy.
Severely broken ankles may require surgery.
