Differentiating Common Ankle Injuries

Sprained Ankle vs Broken Ankle

The ankle is a complex joint that plays a vital role in our daily mobility, making it susceptible to a variety of injuries. Two of the most common conditions affecting the ankle are sprains and fractures. Understanding the key differences between these two types of injuries is crucial for ensuring prompt and appropriate treatment.

Broken Ankle

A broken ankle, also known as an ankle fracture, occurs when one or more of the three bones that make up the ankle joint (the tibia, fibula, and talus) are broken. This type of injury typically results from a sudden, high-impact event, such as a fall, a car accident, or a sports-related trauma.

Ankle Fracture Causes

There are several common causes of ankle fractures, including:

  1. Rotational injuries: When the ankle is twisted beyond its normal range of motion, the bones can snap or break.
  2. Impact injuries: Sudden, forceful impacts, such as those experienced in a car accident or a high-impact fall, can lead to broken bones in the ankle.
  3. Repetitive stress: Repetitive activities, like running or jumping, can cause stress fractures, which are small cracks in the bone.

Ankle Sprain

In contrast, an ankle sprain refers to an injury to the ligaments, which are the tough, fibrous bands of tissue that connect the bones in the ankle joint. Sprains occur when these ligaments are stretched, partially torn, or completely ruptured due to sudden movements or impacts.

Ankle Sprain Causes

Ankle sprains are often caused by:

  1. Sudden twisting or rolling of the ankle, such as when stepping on an uneven surface or landing incorrectly during athletic activities.
  2. Overexertion or overuse of the ankle, leads to strain on the ligaments.
  3. Direct impact to the ankle, as may occur in a fall or collision.

Broken Ankle Symptoms vs Sprain Ankle

To further illustrate the differences between a sprained and broken ankle, consider the following table:

SymptomAnkle SprainAnkle Fracture
Pain IntensityMild to moderate, gradually worseningImmediate, severe, and sharp
DeformitySwelling and bruising, but no obvious deformityVisible deformity and misalignment of the ankle joint
Ability to Bear WeightMay be able to bear some weight, even if painfulUnable to bear any weight on the affected ankle
SensationNo numbness or tinglingPotential numbness, tingling, or loss of sensation in the foot
Sound at InjuryPopping sound, or silentCracking or crunching sound

Diagnosis Of Sprained vs Broken Ankle

Accurately diagnosing an ankle injury requires a thorough medical evaluation by a healthcare professional, such as an orthopedic specialist or sports medicine physician. The diagnostic process typically involves the following steps:

1. Physical Examination

The healthcare provider will carefully examine the ankle, assessing for tenderness, swelling, bruising, and range of motion.

2. Imaging Tests

If a fracture is suspected, the provider may order X-rays, CT scans, or MRI scans to visualize the bones and determine the extent of the injury.

3. Diagnostic Tests

Nerve conduction studies or electromyography (EMG) [Source: Mayo Clinic]may be performed to evaluate potential nerve damage associated with a fracture.

It’s important to note that even with a comprehensive evaluation, it can sometimes be challenging to differentiate between a sprain and a fracture, especially in more severe cases. In these situations, the healthcare provider may need to monitor the injury’s progression and response to initial treatment before making a final diagnosis.

Sprained Ankle Treatments

If your healthcare provider determines that you have a sprained ankle, the initial treatment approach typically involves the RICE (Rest, Ice, Compression, Elevation) protocol:

Rest: Avoid putting weight on the affected ankle and limit physical activity to allow the ligaments to heal.

Ice: Apply ice packs to the ankle for 15-20 minutes several times a day to reduce swelling and pain.

Compression: Use an elastic bandage or compression sleeve to support the ankle and prevent further swelling.

Elevation: Keep the ankle elevated above the level of your heart to help reduce swelling.

Additionally, your healthcare provider may recommend:

  • Over-the-counter anti-inflammatory medications to manage pain and inflammation.
  • Immobilization, such as a splint or boot, protects the ankle and prevents further injury.
  • Physical therapy to help regain strength, flexibility, and stability in the ankle.

The duration of recovery for a sprained ankle can vary widely, depending on the severity of the injury. Mild sprains may heal within a few weeks, while more severe sprains can take several months to fully recover.

Treatments For A Broken Ankle

If your healthcare provider determines that you have a broken ankle, the treatment plan will depend on the specific nature and severity of the fracture. Potential treatments may include:

Immobilization: Your provider may place your ankle in a cast or splint to keep the bones in alignment and prevent further movement.

Reduction: In cases where the bones are displaced, your provider may need to manually realign the bones before immobilizing the ankle.

Surgery: Severely displaced or unstable fractures may require surgical intervention, such as the placement of plates, screws, or other hardware to stabilize the bones during the healing process.

Pain Management: Your provider may prescribe pain medications to help you manage discomfort during the recovery period.

Physical Therapy: Once the bone has begun to heal, you may be referred to a physical therapist to help regain strength, flexibility, and range of motion in the ankle.

The recovery timeline for a broken ankle can vary widely, depending on the severity of the fracture and the need for surgical intervention. In general, non-displaced fractures may heal within 6-8 weeks, while more complex breaks can take several months to fully recover.


Distinguishing between a sprained and broken ankle is crucial for ensuring prompt and appropriate treatment. While these two conditions can share similar symptoms, recognizing the key differences in pain intensity, deformity, weight-bearing ability, sensation, and sound at the time of injury can help guide you toward the right medical care.

Ultimately, seeking evaluation from a qualified healthcare provider is the best way to obtain an accurate diagnosis and develop an effective treatment plan. By following the recommended guidelines for rest, ice, compression, and elevation, as well as any additional therapies or interventions prescribed by your provider, you can optimize your chances of a successful and timely recovery.

Remember, when it comes to ankle injuries, it’s always better to err on the side of caution. Don’t hesitate to seek medical attention, even if you suspect a minor sprain. With the right care and attention, you can overcome the challenges of an ankle injury and regain your mobility and independence.


Q1. How can I tell if my ankle is sprained or broken?

The key differences lie in the intensity of pain, presence of deformity, ability to bear weight, sensation, and sound at the time of injury. Severe, immediate pain, visible deformity, inability to bear weight, and numbness or tingling are more indicative of a broken ankle.

Is it okay to walk on a sprained ankle?

It depends on the severity of the sprain. In mild cases, you may be able to put some weight on the ankle, but it’s generally recommended to avoid bearing full weight until the initial swelling and pain subside. Attempting to walk on a severely sprained ankle can worsen the injury.

Q3. How long does it take to heal a broken ankle?

Recovery times for a broken ankle can vary widely, depending on the severity of the fracture and whether surgery is required. Non-displaced fractures may heal within 6-8 weeks, while more complex breaks can take several months to fully recover.

Q4. Can I treat a broken ankle at home?

No, a broken ankle requires professional medical treatment. Attempting to treat a broken ankle at home can lead to serious complications, such as improper bone alignment or delayed healing. Seek immediate medical attention if you suspect a broken ankle.

Q5. How can I prevent ankle injuries?

Strengthening the muscles around the ankle, maintaining flexibility, and wearing proper, supportive footwear can help reduce the risk of ankle sprains and fractures. Additionally, being cautious on uneven surfaces and during physical activities can help prevent sudden, unexpected ankle injuries.
