🦶 What Is an Ankle Sprain?

An ankle sprain is a common musculoskeletal injury that involves the tearing or overstretching of ligaments — the tough bands of fibrous tissue that connect bones. Most ankle sprains affect the lateral ligaments on the outside of the ankle and occur when the foot rolls inward unexpectedly.

🔍 Types of Ankle Sprains

1. Lateral Ankle Sprain (Most Common)

• Involves damage to the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL).

• Caused by inversion injury (foot twists inward).

2. Medial Ankle Sprain

• Affects the deltoid ligament on the inside of the ankle.

• Caused by eversion injury (foot twists outward).

• Less common, often more severe.

3. High Ankle Sprain

• Involves the syndesmotic ligaments between the tibia and fibula.

• Occurs with forceful twisting injuries, often in sports.

• Takes longer to heal.

🎯 Causes of Ankle Sprains

• Walking or running on uneven surfaces

• Twisting or rolling the ankle suddenly

• Jumping and landing awkwardly

• Sports injuries (football, basketball, soccer)

• Wearing high heels or unstable footwear

• Weak or previously injured ankle

⚠️ Symptoms of Ankle Sprain

• Sudden pain after a twist or fall

• Swelling around the ankle joint

• Bruising or skin discoloration

• Tenderness to touch

• Difficulty bearing weight

• Instability or feeling of "giving way"

• In severe cases: popping sound at the time of injury

🩺 Grades of Ankle Sprain

Grade	Description	Symptoms
I	Mild stretch	Mild pain, swelling, minimal instability
II	Partial tear	Moderate pain, swelling, bruising, trouble walking
III	Complete tear	Severe pain, swelling, inability to bear weight, ankle instability

🧪 Diagnosis

A healthcare provider will:

• Take medical history

• Perform a physical exam

• May order X-rays to rule out fractures

• Use MRI or ultrasound if severe ligament injury is suspected

💊 Treatment & Management

🧊 R.I.C.E. Method (First 48-72 hours)

• Rest: Avoid putting weight on the ankle

• Ice: Apply for 15–20 minutes every 2–3 hours

• Compression: Use elastic bandage to reduce swelling

• Elevation: Keep ankle raised above heart level

🏃‍♀️ Rehabilitation

• After the acute phase, gradual movement and strengthening are essential:

  • Range of motion exercises

  • Stretching the calf and ankle

  • Balance training

  • Strengthening surrounding muscles

🧑‍⚕️ When to See a Doctor

• If swelling or pain is severe

• If you can’t walk more than a few steps

• If symptoms persist beyond a week

🛡️ Prevention Tips

• Warm up before sports or activity

• Use supportive footwear

• Strengthen ankle and leg muscles

• Practice balance exercises

• Tape or brace weak ankles during physical activity

• Avoid uneven surfaces when possible

❓ FAQs

Q: How long does an ankle sprain take to heal?

• Mild (Grade I): 1–2 weeks

• Moderate (Grade II): 3–6 weeks

• Severe (Grade III): 8+ weeks, sometimes requiring surgery

Q: Can I walk on a sprained ankle?

• Only if mild. For moderate or severe, avoid weight-bearing until a doctor advises.

Q: What happens if a sprain is untreated?

• It can lead to chronic ankle instability, repeated injuries, and long-term joint issues.
