Ankle Fractures

The ankle joint is formed by three bones: the tibia (shinbone), fibula (smaller lower leg bone), and talus (ankle bone). Together, these bones and the surrounding ligaments provide stability and allow the foot to move during walking, running, and other activities.

When one or more of these bones break, an ankle fracture occurs. Some fractures are relatively minor and remain stable during healing, while others can significantly disrupt the stability of the joint and require surgical intervention. At Fox Valley Orthopedics, we provide personalized treatment plans designed to restore ankle strength, alignment, and function.

What Is an Ankle Fracture?

An ankle fracture is a crack or break in one or more bones that make up the ankle joint. The injury may range from a small fracture that causes minimal displacement to a severe injury involving multiple fractures and ligament damage.

Ankle fractures may affect:

• The tibia
• The fibula
• The talus
• Multiple bones simultaneously

Because the ankle bears weight during nearly every movement, proper diagnosis and treatment are critical to ensure long-term joint health and mobility.

What Types of Ankle Fractures Are There?

Several different fracture patterns can affect the ankle.

Lateral Malleolus Fracture

This fracture affects the lower end of the fibula on the outside of the ankle. It is one of the most common types of ankle fractures.

Medial Malleolus Fracture

A medial malleolus fracture occurs on the inside of the ankle and affects the lower portion of the tibia.

Bimalleolar Fracture

A bimalleolar fracture involves both the medial and lateral malleoli, making the ankle less stable and often requiring surgical treatment.

Trimalleolar Fracture

A trimalleolar fracture affects three separate portions of the ankle and is generally considered a serious injury requiring advanced treatment.

Stress Fractures

Stress fractures are small cracks that develop over time due to repetitive stress and overuse rather than a single traumatic event.

What Causes Ankle Fractures?

Ankle fractures can occur from both high-impact trauma and lower-energy twisting injuries.

Common causes include:

• Falls
• Sports-related injuries
• Twisting the ankle
• Motor vehicle accidents
• Workplace accidents
• Jumping and landing awkwardly
• Direct blows to the ankle
• Running and repetitive impact activities
• Osteoporosis and weakened bones

Athletes and older adults are often at increased risk depending on the mechanism of injury and underlying bone health.

What Are the Symptoms of an Ankle Fracture?

Symptoms may vary depending on the severity of the fracture.

Common signs and symptoms include:

• Severe ankle pain
• Swelling
• Bruising
• Tenderness
• Difficulty walking
• Inability to bear weight
• Ankle instability
• Visible deformity
• Limited range of motion
• Pain that worsens with movement

In some cases, a fracture can produce symptoms similar to a severe ankle sprain, which is why professional evaluation is important.

How Is an Ankle Fracture Diagnosed?

Diagnosing an ankle fracture begins with a comprehensive orthopedic evaluation.

Diagnostic evaluation may include:

• Review of symptoms and injury history
• Physical examination
• Assessment of ankle stability
• Evaluation of swelling and tenderness
• X-rays
• CT scans for complex fractures
• MRI imaging when ligament injuries are suspected

Imaging studies help identify the location and severity of the fracture while determining whether additional injuries are present.

How Is an Ankle Fracture Treated?

Treatment depends on the location, severity, and stability of the fracture.

What Nonsurgical Treatments Are Available for Ankle Fractures?

Stable fractures often heal successfully without surgery.

Nonsurgical treatment options may include:

• Casting
• Walking boots
• Crutches
• Activity modification
• Ice and elevation
• Pain management
• Physical therapy during recovery

The goal of conservative treatment is to allow the bone to heal in proper alignment while maintaining joint function.

When Is Surgery Recommended for Ankle Fractures?

Surgery may be recommended when:

• The fracture is displaced
• Multiple bones are fractured
• The ankle joint is unstable
• Ligament damage is present
• The fracture extends into the joint
• Conservative treatment is unlikely to restore proper alignment

Surgical options may include:

• Open reduction and internal fixation (ORIF)
• Plates and screws
• Pins or rods
• Ligament repair
• Joint reconstruction procedures

The appropriate treatment depends on the fracture pattern, patient health, and activity goals.

What Does Ankle Fracture Recovery Look Like?

Recovery varies depending on the severity of the fracture and whether surgery is required.

Minor fractures may heal within several weeks, while more complex injuries can require several months of rehabilitation.

Recovery often includes:

• Immobilization in a cast or boot
• Weight-bearing restrictions
• Physical therapy
• Strengthening exercises
• Balance and stability training
• Gait retraining
• Progressive return to sports and daily activities

Following your treatment plan and rehabilitation program is critical for restoring full ankle function and reducing the risk of future complications.

What Complications Can Occur if an Ankle Fracture Is Left Untreated?

Without proper treatment, ankle fractures may heal incorrectly and lead to long-term problems.

Potential complications include:

• Chronic pain
• Ankle instability
• Malunion (healing in the wrong position)
• Nonunion (failure to heal)
• Loss of range of motion
• Arthritis
• Weakness
• Difficulty walking
• Reduced athletic performance

Early diagnosis and treatment can help prevent these complications and improve long-term outcomes.
