About - An ankle fracture is a break or crack in one or more of the bones that make up the ankle joint. The ankle is formed by three main bones: the tibia (shinbone), fibula (the smaller bone of the lower leg), and talus (a bone in the foot). A fracture can occur in any of these bones and may range from a small, stable crack to a severe break in which the bones become displaced or the skin is damaged. Ankle fractures are common injuries and can occur at any age. They may result from a simple misstep or fall, but high-impact injuries such as road traffic accidents or sports injuries can cause more complicated fractures. Some ankle fractures are stable and can be treated without surgery, while displaced, unstable, or open fractures may require surgical treatment. Prompt medical assessment is important because an improperly treated fracture can lead to persistent pain, stiffness, instability, or arthritis of the ankle.
The signs and symptoms of an ankle fracture can vary depending on the location and severity of the injury. Common symptoms include:
Severe pain: Pain may begin suddenly at the time of injury and can become worse when moving the ankle or attempting to stand.
Tenderness: The area around the injured bone may be very painful to touch or pressure.
Swelling: Swelling around the ankle commonly develops soon after the injury.
Bruising: The skin may become red, purple, or bruised around the ankle and sometimes into the foot.
Difficulty walking: A person may be unable to walk or bear weight on the affected leg.
Pain with movement or activity: Moving the ankle or putting weight on it may significantly increase pain.
Deformity or dislocation: In a severe fracture, the ankle may appear crooked, misshapen, or out of its normal position.
Bleeding or an open wound: A severe fracture may break through the skin, causing bleeding.
Bone visible through the skin: In an open fracture, a broken bone may protrude through the skin. This is a medical emergency.
Numbness or tingling: Damage or pressure involving nerves or blood vessels may cause altered sensation in the foot or toes.
Not every ankle fracture causes all of these symptoms. It can sometimes be difficult to distinguish a fracture from a severe sprain without medical examination and appropriate imaging.
An ankle fracture usually occurs when a force or twisting movement places more stress on the bones than they can withstand. Common causes include:
Falls- Falling from a height or slipping and landing awkwardly can twist or directly impact the ankle and cause a fracture.
Road Traffic Accidents- Car, motorcycle, bicycle, and other road traffic accidents can produce significant forces that may cause complex or multiple fractures.
Sports Injuries- Activities such as football, basketball, running, skiing, and other sports can result in ankle fractures, particularly when the ankle twists, rolls, or receives a direct blow.
Heavy Impact- A heavy object falling on the ankle or a strong direct impact can break one or more ankle bones.
Missteps or Twisting Injuries- Stepping into a hole, landing awkwardly, or suddenly twisting the ankle may cause a fracture. A seemingly minor injury can occasionally cause a fracture, particularly in people with weakened bones.
Overuse- Repeated stress on a bone can sometimes result in a stress fracture. Stress fractures are different from acute fractures caused by a single major injury and may develop gradually with repetitive activity.
Ankle fractures may be classified according to the bone involved, the location of the break, and whether the fractured bones remain properly aligned.
Stable Fracture- The broken bones remain relatively well aligned and the ankle joint may remain stable. Some stable fractures can be treated without surgery.
Displaced Fracture- The broken bone fragments have moved out of their normal position. Depending on the severity, the bones may need to be repositioned and stabilized.
Open Fracture- An open fracture occurs when the broken bone is exposed through a wound in the skin. It carries a significant risk of infection and requires urgent medical treatment.
Closed Fracture - In a closed fracture, the skin over the fracture remains intact.
Stress Fracture - A stress fracture is a small crack caused by repeated stress rather than a single major traumatic event. It may initially cause pain mainly during activity.
A healthcare professional will examine the ankle and ask about how the injury occurred. The examination may include checking swelling, tenderness, movement, skin condition, and blood circulation and sensation in the foot. X-rays are commonly used to identify ankle fractures and determine the position of the bones. Depending on the injury, additional imaging may be recommended:
CT scan: May provide detailed images of complex fractures and help with surgical planning.
MRI: May be useful when a stress fracture or associated soft-tissue injury is suspected and the diagnosis is not clear on X-ray.
Treatment depends on the type and severity of the fracture, whether the bones are displaced, whether the ankle joint is stable, and the person’s overall health.
For some injuries, initial treatment may include protecting the ankle, limiting weight-bearing, elevating the leg, and applying ice wrapped in a cloth for short periods to help reduce swelling. Ice should not be applied directly to the skin.
A stable fracture may be treated with a splint, cast, or walking boot to keep the ankle protected while the bone heals. The healthcare professional will advise when and how much weight can safely be placed on the affected leg.
If the broken bones have moved out of alignment, a doctor may need to reduce the fracture by carefully moving the bone fragments back into their proper position. This may be performed with appropriate pain relief or anesthesia.
Surgery may be recommended when the fracture is unstable, significantly displaced, involves the joint, or cannot be adequately maintained in the correct position with non-surgical treatment. Surgical fixation may involve plates, screws, rods, or other fixation devices to hold the bones in the correct position while they heal. Open fractures require urgent treatment, including cleaning of the wound and management of the fracture to reduce the risk of serious infection.
Healing time varies according to the type of fracture, its severity, treatment, and the person’s general health. Many ankle fractures take several weeks to heal, but full recovery can take longer, particularly after a severe fracture or surgery. Once the healthcare professional considers it safe, physiotherapy and rehabilitation exercises may help restore:
Ankle movement and flexibility
Muscle strength
Balance and coordination
Walking ability
Normal daily activities
Returning to sports or strenuous activity should be gradual and based on medical advice.
An ankle injury should receive urgent medical attention if:
The ankle appears severely deformed or out of position.
A bone is visible through the skin.
There is significant bleeding.
The foot or toes become numb, pale, blue, or unusually cold.
There is severe or rapidly worsening pain or swelling.
The person cannot move the foot or toes normally.
The injury was caused by a major accident.
Do not attempt to straighten a severely deformed ankle or push a protruding bone back under the skin. Keep the injured ankle as still as possible and seek emergency medical care.
If you suspect an ankle fracture, consult an Orthopedic Surgeon (Orthopaedic Surgeon). Depending on the severity of the injury, emergency physicians, radiologists, physiotherapists, and other healthcare professionals may also be involved in diagnosis and recovery.
Walking may be difficult or impossible after an ankle fracture. Do not put weight on the injured ankle unless a healthcare professional has confirmed that it is safe to do so.
An ankle fracture involves a break in a bone, whereas a sprain involves injury to one or more ligaments around the joint. The symptoms can be similar, so medical assessment and imaging may be necessary to determine whether a bone is broken.
No. Some stable, well-aligned fractures can be treated with immobilization and restricted weight-bearing. Surgery is more likely to be required for unstable or significantly displaced fractures.
Healing time varies. Many fractures require several weeks for the bone to heal, while complete recovery of strength, movement, and function may take several months, especially after a complicated fracture or surgery.
A serious ankle fracture, particularly one involving the joint surface, can increase the risk of developing arthritis in the affected ankle later in life.
Yes. If fractured bones heal in an abnormal position, the condition is called malunion. Proper diagnosis, alignment, treatment, and follow-up help reduce this risk.
