About Ankle Fractures

Overview

A fractured ankle occurs when one or more of the bones around the ankle joint break. The ankle joint is made up of three bones: the tibia (shinbone), the fibula (smaller long bone in the lower leg), and the talus (bone above the heel bone and below the fibula and tibia). An ankle fracture can range from a hairline fracture to a displaced fracture that may require surgery. It is a relatively common injury, accounting for about 15 percent of ankle injuries seen in emergency departments. Ankle fractures can be caused by twisting injuries or direct impact to the ankle, such as from a car accident or sports-related impact. Symptoms include pain, swelling, difficulty walking or moving the foot, and sometimes a broken bone pushing against the skin. Treatment for an ankle fracture depends on its severity and location, with surgery not always necessary.

Causes and Risk Factors

Fractured ankles can occur due to various factors such as traumatic events or injuries. Non-modifiable risk factors are risk factors that cannot be changed. Non-modifiable risk factors of a fractured ankle include:

• Age and gender: Males are more predominant in younger age groups, while females are more predominant in older age groups.
• Osteoporosis: Reduced bone mineral density is associated with an increased risk of ankle fractures.

Modifiable risk factors are risk factors that can be changed or influenced. Modifiable risk factors for a fractured ankle include:

• Participating in sports: Engaging in certain sports like basketball, football, soccer, and skiing may increase the risk.
• Body mass index (BMI): Higher BMI is associated with an increased risk.
• Smoking: Smoking has been identified as a modifiable risk factor.
• Falls and alcohol consumption: One or more falls in the previous year and alcohol consumption can contribute to the risk.

It's important to note that these risk factors can vary for each individual, so it's always recommended to consult with a healthcare professional for personalized advice.

Symptoms

The most common early symptoms of a fractured ankle include:

• Immediate and severe pain
• Swelling
• Bruising
• Tenderness to the touch
• Inability to put weight on the damaged ankle

As the fracture progresses or becomes more severe, additional symptoms may occur, such as:

• Difficulty walking or moving the foot
• Difficulty bearing weight on the ankle
• Deformity of the ankle
• Dizziness from pain
• Bone sticking out of the skin (in severe cases)
• Bleeding, if the bone pierces the skin (in severe cases)

It's important to note that some symptoms of a fractured ankle, like severe pain and swelling, can also be present in other ankle disorders. If you suspect a fractured ankle or experience any of these symptoms, it's best to seek medical attention for an accurate diagnosis and appropriate treatment.

Diagnosis

To diagnose a fractured ankle, doctors commonly perform the following examinations, tests, and procedures:

• Medical history review: The doctor will ask about your symptoms, medical history, and the events leading up to the injury.
• Physical examination: The doctor will carefully examine your ankle, foot, and lower leg for signs of swelling, tenderness, bruising, deformity, and range of motion.
• X-ray: This is the most common test used to diagnose a fracture. It can show any breaks or displacement in the bone and determine how many pieces of broken bone there are.
• Computed tomography (CT) scan: This imaging test provides more detailed information about the injury, especially if it extends to the ankle joint.
• Magnetic resonance imaging (MRI) scan: This high-resolution imaging test helps evaluate damage to ligaments and soft tissues.

It's important to seek medical attention if you suspect a fractured ankle or have severe pain, swelling, or bruising after an injury. Your doctor can provide a proper diagnosis based on these examinations and tests.

Treatment Options

The goals of treatment for a fractured ankle are to stabilize the ankle, promote healing, relieve pain, restore mobility, and prevent complications. Here are the different treatment options and how they work towards achieving these goals:

Medications:

• Over-the-counter or prescription pain medication: These medications help manage pain and discomfort during the healing process. They can reduce inflammation and provide relief.

Therapies:

• Physical therapy: Gentle exercises and stretches prescribed by a physical therapist can help improve mobility, strength, and flexibility in the ankle. This therapy aims to restore function and prevent stiffness.
• Regenerative medications or orthobiologics: Platelet-rich plasma (PRP) or stem cell therapy may be used to promote healing and tissue regeneration in the ankle.
• Custom orthotics or braces: These devices provide support and stability to the ankle during the healing process.

Therapeutic procedures:

• Surgery: In cases where surgery is necessary, the procedure aims to stabilize the ankle by realigning the bones, inserting pins or screws, or using plates and screws. Bone grafting may also be performed to aid in bone regeneration.
• Nerve blocks: Ankle blocks or peripheral nerve blockades may be used to manage pain associated with nerve damage.

Self-care and health behavior changes:

• Rest, ice, elevation: These home remedies can help reduce swelling and promote healing. Resting the ankle, applying ice packs, and elevating the leg can alleviate symptoms.
• Gentle exercises: Performing gentle exercises as recommended by a healthcare professional can improve circulation, reduce stiffness, and enhance recovery.

It's important to note that treatment plans may vary depending on individual circumstances. Always consult with a healthcare professional for personalized advice. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for side effect information.
