A sprain is the stretching or tearing of ligaments, which connect adjacent bones and provide stability to a joint. An ankle sprain is a common injury that occurs when you suddenly fall or twist the joint or when you land your foot in an awkward position after a jump. Most commonly it occurs when you participate in sports or when you jump or run on a surface that is irregular. Ankle sprains can cause pain, swelling, tenderness, bruising, stiffness, and inability to walk or bear weight on the ankle.
The diagnosis of an ankle sprain is usually made by evaluating the history of injury and physical examination of the ankle. X-ray of your ankle may be needed to confirm if a fracture is present. The most common treatment recommended for ankle sprains is rest, ice, compression and elevation (RICE).
Rest: You should not move or use the injured part to help to reduce pain and prevent further damage. Crutches may be ordered that help while walking.
Ice: An ice pack should be applied over the injured area up to 3 days after the injury. You can use a cold pack or crushed ice wrapped in a towel. Never place ice directly over the skin. Ice packs help reduce swelling and relieve pain.
Compression: Compression of the injured area helps to reduce swelling and bruising. This is usually accomplished by using an elastic wrap for a few days or weeks after the injury.
Elevation: Place the injured ankle above your heart level to reduce swelling. Elevation of an injured leg can be done for about 2 to 3 hours a day.
The doctor may also use a brace or splint to reduce motion of the ankle and to prevent reinjury to the ankle ligaments. Anti-inflammatory pain medications may be prescribed to help reduce pain and control inflammation.
During your recovery, rehabilitation exercises are recommended to strengthen and improve range of motion in your foot. You may need to use a brace or wrap to support and protect your ankle during sports activities. Avoid pivoting and twisting movements for 2 to 3 weeks. To prevent further sprains or re-injury you may need to wear a semi-rigid ankle brace during exercise, special wraps and/or high-top lace shoes.
