What is an ankle sprain?
An ankle sprain is an injury that causes a stretch or tear
of one or more ligaments in the ankle joint. Ligaments are
strong bands of tissue that connect bones at the joint.
Sprains may be graded I, II, or III depending on their
severity:
- grade I sprain: pain with minimal damage to the
ligaments
- grade II sprain: more ligament damage and mild looseness
of the joint
- grade III sprain: complete tearing of the ligament and
the joint is very loose or unstable.
Sometimes sprains are just classified as mild or severe,
depending on the amount of ligament damage.
Most sprains occur on the outside part of the ankle, but
they can occur on the inside as well.
How does it occur?
A sprain is caused by twisting your ankle. Your foot
usually turns in or under but may turn to the outside.
What are the symptoms?
Symptoms of a sprained ankle include:
- mild aching to sudden pain
- swelling
- discoloration
- inability to move the ankle properly
- pain in the ankle even when you are not putting any
weight on it.
How it is treated?
Treatment may include:
- Applying ice packs to your ankle for 20 to 30 minutes
every 3 to 4 hours for the first 2 to 3 days or until the
pain goes away. Thereafter, ice your ankle at least once
a day until the other symptoms are gone.
- Elevating your ankle by placing a pillow underneath your
foot for 1 day. Try to keep your ankle above the level
of your heart.
- Wrapping an elastic bandage around your ankle to keep the
swelling from getting worse. Keep the wrap on for 2
days.
- Wearing a lace-up brace or ankle stirrup (an Aircast or
Gel cast).
- Using crutches until you can walk without pain.
- Taking anti-inflammatory pain medication such as
ibuprofen.
- Doing ankle exercises to improve your ankle strength and
range of motion. The exercises will help you return to
your normal activity or sports.
Rarely, severe ankle sprains with complete tearing of the
ligaments need surgery. After surgery your ankle will be in
a cast for 4 to 8 weeks.
How long will the effects last?
The length of recovery depends on many factors:
- age
- health
- severity of injury and previous injuries to that joint.
How can I help prevent an ankle sprain?
To help prevent an ankle sprain, follow these guidelines:
- Wear proper, well-fitting shoes when you exercise.
- Stretch gently and adequately before and after athletic
or recreational activities.
- Avoid sharp turns and quick changes in direction and
movement.
- Consider taping the ankle or wearing a brace for
strenuous sports, especially if you have a previous
injury.
