Sprained Ankle vs. Broken Ankle: Key Differences, Diagnosis, and Treatment

Ankle injuries are very common, especially when you play sports or have an accident. It's important to know if your ankle is sprained or broken so you can get the right treatment and heal properly. 

Both can hurt a lot and cause swelling and bruising, but they are different in how serious they are and how they are treated. A sprained ankle happens when the ligaments, which are the bands that support your ankle, are stretched too much or torn. A broken ankle means one or more of the bones in your ankle are cracked or broken.

Knowing the difference helps you decide what to do, from first aid to long-term care. In this article, we’ll explain how to tell a sprained ankle vs broken ankle, how doctors check for them, and the best ways to treat them. By the end, you'll know what to do if you or someone you know experiences a painful ankle.

A sprained ankle, also known as an ankle sprain [¹], occurs when the ligaments—the tough bands of tissue that connect bones and support the ankle joint—are overstretched or torn. 

This type of ankle injury is typically caused by sudden, awkward movements or overexertion, often during sports or everyday activities.

• Twisting or rolling the ankle awkwardly
• Jumping or landing improperly
• Stepping on an uneven surface

• Pain that ranges from mild to severe, depending on the extent of the ligament damage
• Swelling around the ankle joint
• Bruising that can develop several hours after the injury
• Limited range of motion or difficulty walking

A broken ankle [²], or ankle fracture, involves a break in one or more bones forming the ankle joint, including the tibia, fibula, or talus. 

This type of injury is generally more severe than a sprain and often results from high-impact trauma or severe stress on the joint.

• High-impact trauma such as a car accident or a significant fall
• Severe twisting or bending of the ankle
• Direct blows to the ankle area

• Severe pain that worsens with movement or pressure
• Swelling that is often more pronounced compared to a sprain
• Bruising and deformity at the site of the fracture
• Inability to bear weight on the affected foot or visible deformity where the bone may protrude

When assessing a sprained vs broken ankle, it’s essential to differentiate between the two. The initial assessment focuses on observing the severity of pain, swelling, and other symptoms to determine the likely nature of the injury.

For a sprained ankle, you might notice:

• Mild to moderate pain that may increase with movement
• Swelling that may be localized around the ankle joint
• Bruising appearing over time

For a broken ankle, signs can include:

• Severe pain that often feels sharp and intense
• Extensive swelling that may extend beyond the immediate ankle area
• Severe bruising and potential deformity or abnormal positioning of the ankle

To accurately diagnose the injury, a healthcare professional will use several diagnostic tools and techniques:

• X-ray imaging: The primary method for diagnosing a bone fracture. X-rays provide clear images of the bone structure, revealing any breaks or cracks in the ankle bones. An X-ray can also reveal a fractured ankle, highlighting the importance of accurate diagnosis.
• Physical Examination: A thorough physical examination involves assessing the range of motion, tenderness, and swelling. The examiner will check for deformity or instability in the ankle joint.
• Differential Diagnosis: This process involves eliminating other possible injuries or conditions, such as tendon or joint dislocations, to ensure accurate diagnosis and treatment.

Accurate diagnosis is crucial for determining the proper treatment and rehabilitation plan. Misdiagnosis or inadequate assessment can lead to complications and prolonged recovery.

Immediate first aid is crucial for managing sprained and broken ankles. Proper care can help reduce pain and swelling and prevent further damage.

For a sprained ankle

• Rest: For ankle sprains, avoid putting weight on the injured ankle to prevent further strain on the ligaments.
• Ice: Apply ice or a cold compress to the affected area for 15 to 20 minutes every 1-2 hours during the first 48 hours to reduce swelling and pain.
• Compression: To help control swelling, use an elastic bandage to apply gentle compression around the ankle. Be careful not to wrap too tightly, as it may impede circulation.
• Elevation: Keep the ankle above heart level whenever possible to reduce swelling.

For a broken ankle

• Immobilization: Ensure the injured ankle remains as still as possible. Avoid moving the foot or ankle to prevent further injury. A broken ankle involves a broken bone; immobilization is pivotal to ensure proper healing and prevent complications.
• Ice: Apply ice to manage swelling and pain, but avoid direct contact with the skin.
• Seek Medical Attention: Getting professional medical help immediately is crucial, as a broken ankle often requires specific treatment such as casting or surgery.

For a sprained ankle:

• Rest and Immobilization: Avoid activities that put stress on the ankle. In mild cases, a brace or splint may provide additional support.
• Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help alleviate pain and reduce inflammation.
• Physical Therapy: Once the initial symptoms subside, physical therapy may be advisable to strengthen the ankle, improve flexibility, and prevent future injuries.

For a broken ankle

• Immobilization: For ankle fractures, a cast or splint is typically used to keep the bones in place and allow for proper healing.
• Orthopedic Care: In more severe cases, surgery may be necessary to realign the bones and stabilize the ankle with screws or plates.
• Rehabilitation: Rehabilitation exercises are essential to restore strength and function after a cast or surgery. Physical therapy helps regain mobility and ensures the ankle heals correctly.

A sprained ankle happens when the ligaments are stretched or torn. Recovery time depends on how bad the sprain is. A mild sprain may heal in a few weeks, but a more serious one could take months to get better.

A broken ankle is when a bone in the ankle is fractured. It usually takes about 6 to 12 weeks for the bone to heal, but it could take longer to return to normal activities.

It’s important to understand the recovery time and treatment plan for both a sprained ankle vs broken ankle. Following the doctor’s instructions helps the ankle heal properly and can prevent long-term problems like pain or weakness.

Sprained and broken ankles can have long-term effects if not properly treated or if the injury is severe.

For a sprained ankle

• Chronic Pain or Instability: Some individuals may experience ongoing pain or a feeling of instability in the ankle, particularly if the sprain is severe. Untreated sprains can lead to chronic ankle instability, which results in the ankle giving way during movement and can cause persistent swelling and discomfort.
• Recurrent Injuries: A sprained ankle can increase the likelihood of future sprains if the ligaments do not fully recover or if proper rehabilitation is not followed.

For a broken ankle

• Persistent Pain: Even after the bone heals, some people may experience chronic pain or discomfort in the ankle bone.
• Limited Range of Motion: Stiffness or a reduced range of motion may occur, especially if the injury requires extensive immobilization.
• Post-Traumatic Arthritis: In severe cases, arthritis can develop in the joint due to the trauma, leading to long-term joint issues and pain.

Physical therapy and rehabilitation are important for minimizing these long-term effects and ensuring a full recovery.

Preventing ankle injuries can significantly reduce the risk of sprains and fractures. Here are some effective strategies:

• Ankle Stabilization: Perform strengthening exercises to improve the stability and strength of the ankle. These can include exercises that target the muscles and ligaments around the ankle.
• Proper Footwear: Wear shoes that provide adequate support and cushioning. Avoid high heels or poorly fitted shoes that increase the risk of injury.
• Warm-Up and Stretching: Always perform proper warm-up and stretching exercises before engaging in physical activities or sports to prepare the muscles and ligaments for the demands of the activity.
• Safety Precautions: Be mindful of uneven surfaces and wear protective gear when participating in activities that involve a high risk of injury.

Implementing these prevention strategies can help reduce the likelihood of experiencing an ankle injury and contribute to overall ankle health.

Knowing when to seek professional help is crucial for effectively managing a sprained or broken ankle. Prompt medical attention can significantly improve the outcome of the injury.

For a sprained ankle

• Severe Pain: If the pain is intense and does not improve with rest and basic first aid measures, it’s important to consult a healthcare professional.
• Inability to Bear Weight: Difficulty or inability to weigh the injured ankle may indicate a more serious issue.
• Severe Swelling or Bruising: Extensive swelling or bruising that doesn’t improve could signal a more severe sprain or a potential fracture.

For a broken ankle

• Visible Deformity: Any visible deformity or abnormal ankle positioning indicates that immediate medical attention is necessary.
• Intense Pain: Severe, unrelenting pain that worsens over time and does not respond to pain relief measures requires professional evaluation.
• Inability to Move: If you cannot move the ankle or it isn't easy to move, talk to your doctor.

A professional medical assessment is vital for:

• Accurate Diagnosis: A healthcare provider will use X-ray imaging and physical examination to diagnose the injury's extent accurately.
• Appropriate Treatment: A proper diagnosis ensures that the right treatment plan is followed, whether it involves immobilization, surgery, or rehabilitation.
• Preventing Complications: Early and accurate treatment helps prevent complications such as chronic pain, limited mobility, or improper healing.

If you experience any of these signs or have concerns about your injury, don’t hesitate to seek medical advice. An early consultation can facilitate a faster recovery and help you confidently return to your normal activities.

Distinguishing between a sprained ankle vs broken ankle is crucial for effective treatment and recovery. Sprained ankles involve ligament damage and typically heal with rest and physical therapy, while broken ankles require more extensive care, such as immobilization or surgery. 

Accurate diagnosis through X-ray imaging and prompt first aid are vital. To prevent future injuries, use proper footwear, strengthen your ankles, and practice safety.
