Ankle sprains are one of the most common orthopaedic injuries. There are 25,000 ankle sprains every day in the United States, and makeup over 1,000,000 ER visits per year.

These are so common that many people never seek medical attention, or only see a primary care physician. For this reason, there are many misconceptions about the treatment and about what can be done to alleviate the pain.

Ankle Sprains

It’s also important to see a specialist to rule out other causes of pain after an inversion or twisting injury of the ankle.

Bones are held together by strong, fibrous structures called ligaments. A sprain is a tear in a ligament. The most commonly injured ligament in the ankle is the ATFL (anterior talofibular ligament), followed by the CFL (calcaneofibular ligament), and the deltoid ligament.

Ankle Sprains

The most common injured ligament is the ATFL, followed closely by the CFL. These are often injured at the same time with an inversion injury, and combined, make up 90% of ankle sprains. If there is pain to areas outside of these two, usually an MRI will be ordered as injuries to other ligaments or structures may connote a more severe injury.

The syndesmosis is a collection of ligaments that hold the bones of the leg together (tibia and fibula). This is commonly called a “high ankle sprain” and is a more severe injury, sometimes requiring surgery. Even when nonoperative treatment is possible, this takes about twice as long to heal as a standard ankle sprain.

Possible Related Injuries

Ankle sprains should be seen by a specialist to rule out

  • Lisfranc fracture-dislocation (midfoot sprain/fracture)
  • Ankle fracture
  • Osteochondral lesion of the talus
  • High ankle sprain
  • Structural abnormalities predisposing to sprains
  • Calcaneus or talus fracture
  • Peroneal retinacular injury
  • Ankle Sprains and Instability Treatment

Immobilization and rest by use of a tall cam boot while the pain is severe. Ace bandages and lace-up braces are usually inadequate to truly rest a severe sprain. If you are limping or using crutches, walking in a boot will be a better treatment option. The cam boot may be used for up to six weeks in a standard ankle sprain or twelve in a high ankle sprain.

Ice and anti-inflammatories decrease the pain. Ice should be placed with a tea towel protecting the skin for no more than 20 minutes per hour. Ice is not advised in patients with neuropathy or any numbness in the feet. Speak to your doctor if there is a concern for contraindications to anti-inflammatories such as naproxen or ibuprofen

Physical therapy to strengthen the muscles that are weak and improve balance. Spraining the ankle results in the tearing of nerve fibers that are specific for proprioception, which is our brain’s ability to know where the foot is in space. Physical therapy has been shown to regrow and retrain these nerves and is critical to prevent reinjury.

Occasionally surgery is necessary when the sprains are recurrent, and all non-operative treatments fail.

Ankle Sprains and Instability Diagnosis

A set of high-quality weight-bearing (standing) x-rays are required for diagnosis to rule out fracture and to assess the structure of the foot and ankle, as well as a thorough physical examination. Sometimes, an MRI may be necessary if there is concern for an atypical sprain.

Return to play

To prevent further injury or re-injury, it’s best to wait until your balance has been regained and improved. This requires specific balance training as well as core strengthening. Home exercises can be accelerated with a Bosu ball to gain balance.

I fell down some stairs moving furniture and seriously thought I broke my ankle. Got in that day to see Dixon and was NOT disappointed (my best friend loves her and suggested I see her for my ankle). She was so friendly, figured out my ankle was just severely sprained – not broken- and actually cared about what my best options for recovery were. My follow up appointment was a breeze and because I followed her original instructions – I was back at running and working on my feet with ease and faster than I ever thought possible. Dixon is awesome! She cares and is so real. I recommend her to everyone!

First saw Dr. Dixon for a peroneal tear that was healed over. She was my 4th doctor. All I needed was a custom orthotic. Got it, bought good arch support tennis shoes. After 6yrs. it greatly improved. Previous doctors I went to, I received cortisone injections, foot braces, and recommended to purchase an Amazon orthotic. 2nd problem – I broke my foot on a Sunday. Got in the next day for x-ray and diagnosis. I had 2 breaks in my foot. I was offered surgery which would have been a faster recovery but I opted for the 12 week boot. I’m pretty much out of it now. I love her!!! I’m in the medical field and I know how things work in a medical practice. They’re professional, nice office, nice assistant. I highly recommend her. Sent my sister to her and she also was very happy!
