Key Takeaways
- Ankle sprains involve stretched or torn ligaments, while fractures are breaks in the ankle bones.
- Key differences include the sound at the time of injury (a pop for sprains, a crack for fractures), the location of the pain (soft tissue for sprains, directly over the bone for fractures), and the ability to bear weight.
- An accurate diagnosis from an orthopedic specialist is essential, as incorrect treatment can lead to chronic pain, instability, and arthritis.

Distinguishing a Sprain From a Fracture
After an ankle injury, it’s normal to feel a mix of pain, swelling, and concern. While both a sprain and a fracture can stop you in your tracks, they are fundamentally different injuries that require distinct treatment plans. A sprain affects the ligaments—the tough, fibrous bands that connect bones to other bones. A fracture, on the other hand, is a break in one or more of the bones that make up the ankle joint.
Knowing the difference is critical. Treating a fracture like a sprain can lead to improper healing and long-term complications. Let’s explore the signs that can help you tell whether you have a sprained versus a broken ankle.
Key Symptoms to Watch For
While only a medical professional can provide a definitive diagnosis, certain symptoms can point toward one injury over the other. Pay attention to what you felt and heard when the injury occurred, as well as the specific nature of your pain.
Here is a comparison of common symptoms for an ankle sprain vs. a fracture:
| Symptom | Ankle Sprain | Ankle Fracture |
|---|---|---|
| Sound at Injury | A 'pop' or 'snap' sound as the ligament tears. | A distinct 'crack' or 'snap' sound from the bone breaking. |
| Pain Location | Pain is often more diffuse and centered over the soft tissue of the ankle. | Pain is typically sharp, localized, and directly over the affected bone. |
| Swelling & Bruising | Swelling and bruising appear quickly and can be significant. | Swelling and bruising are present, often severe and immediate. |
| Ability to Bear Weight | You may be able to walk with a limp, though it will be painful. | It is often impossible to put any weight on the injured ankle. |
| Ankle Appearance | The ankle may look swollen and discolored but usually retains its basic shape. | The ankle joint may look visibly deformed or out of place. |
| Numbness/Tingling | Numbness is less common unless swelling is severe. | Numbness or tingling can occur if the fracture affects nerve pathways. |
Why an Accurate Diagnosis is Essential
Self-diagnosing an ankle injury is risky. What might seem like a bad sprain could easily be a fracture, and mistaking one for the other can have serious consequences. Proper treatment depends entirely on an accurate diagnosis.
If a fracture is not identified and stabilized correctly, the bones may not heal in the proper alignment. This can lead to:
- Chronic ankle instability and pain
- Difficulty walking or participating in activities
- An increased risk of developing post-traumatic arthritis
- Long-term joint deformity
Conversely, overtreating a mild sprain with a cast can lead to unnecessary joint stiffness and muscle weakness. Seeing an orthopedic specialist ensures you get the right diagnosis from the start, setting you up for the most effective and efficient recovery possible.
How an Orthopedist Diagnoses Ankle Injuries
When you visit an orthopedic specialist for an ankle injury, they will perform a thorough evaluation to determine the extent of the damage. Dr. Collin Haben uses a combination of physical examination and advanced imaging to provide a precise diagnosis.
Physical Examination
The first step is a hands-on assessment. Dr. Haben will ask about how the injury happened and your symptoms. He will then gently examine the ankle, checking for:
- Points of tenderness directly over the bones and ligaments.
- The range of motion of the ankle joint.
- Signs of instability or looseness in the joint.
- Visible deformities or misalignments.
Imaging Tests
While a physical exam provides important clues, imaging tests are often needed to confirm whether you have a sprain or break in your ankle.
- X-rays: This is the most common tool used to identify fractures. X-rays create clear images of the bones, allowing your doctor to see any breaks, cracks, or chips.
- MRI (Magnetic Resonance Imaging): If a fracture is ruled out but a severe ligament injury is suspected, an MRI may be ordered. This test provides detailed images of soft tissues, including ligaments, tendons, and cartilage, to assess the severity of a sprain.
- CT (Computed Tomography) Scan: For complex fractures, a CT scan can provide a more detailed, three-dimensional view of the bone. This helps in planning for surgery if it is required.
Treatment Options for Sprains vs. Fractures
The treatment plan for your ankle injury will depend entirely on the diagnosis.
Treating Ankle Sprains
For most mild to moderate ankle sprains, the goal is to reduce pain and swelling and allow the ligament to heal. Treatment often involves the R.I.C.E. method:
- Rest: Avoid activities that cause pain.
- Ice: Apply ice packs for 15-20 minutes at a time, several times a day.
- Compression: Use an elastic bandage to control swelling.
- Elevation: Keep your ankle elevated above the level of your heart.
For more severe sprains, Dr. Haben may recommend a brace or walking boot to stabilize the ankle. Physical therapy is also crucial for restoring strength, flexibility, and stability to the joint.
Treating Ankle Fractures
Treatment for a broken ankle depends on which bone is broken and the severity of the break.
- Non-Surgical Treatment: If the fracture is stable and the bones are properly aligned, treatment may involve a cast or a walking boot to immobilize the ankle while it heals. You will likely be instructed not to put weight on it for several weeks.
- Surgical Treatment: If the bones are displaced or the joint is unstable, surgery is often necessary. During surgery, the surgeon repositions the bone fragments and uses plates, screws, or pins to hold them in place while they heal. Following surgery, a period of immobilization and physical therapy is required.

Frequently Asked Questions
Can you walk on a fractured ankle?
While it is extremely painful and generally not possible, some people can walk on a minor, non-displaced fracture. However, attempting to bear weight on a broken ankle can worsen the injury and complicate healing. It is not a reliable way to tell if your ankle is sprained or broken.
How can I tell the difference between an ankle sprain and a fracture at home?
Key indicators of a fracture include a cracking sound at the time of injury, pain localized directly on a bone, visible deformity, and an inability to bear weight. A sprain is more likely if you heard a 'pop' and the pain is in the soft tissue. However, only a doctor can confirm the diagnosis.
How long does it take for a broken ankle to heal?
Healing time for a broken ankle varies depending on the severity of the fracture and the treatment method. Generally, it takes 6 to 12 weeks for the bones to heal. A full return to all activities, especially sports, can take several months and typically requires physical therapy.
