What is a 2nd degree ankle sprain?

This is the partial tearing of ligament fibers. There is mild-moderate laxity. Mild ankle instability. Significant swelling and bruising. Some loss of motion or use of ankle, and trouble walking.

MD Referral

If you get a 2nd degree ankle sprain, you should call your doctor, but unless instructed, wait until the next business day to see your doctor.

X-rays are sometimes needed depending on the exam to rule out a fracture.

Treatment

  • rest
  • no additional force
  • ice 10-15 minutes 3-4 times a day
  • compression: ACE bandage, dressing
  • elevation- this will minimize swelling
  • rehabilitation exercises
  • stabilization

If left untreated, the injury will take longer to heal

  • eversion- this is when the foot is twisted outwards and the inner ligaments are injured.
  • Digitorum longus
  • Peroneus longus
  • Peroneus brevis
  • Soleus
  • Peroneal tendons
