Chronic Ankle Instability: The Danger of Repeated Ankle Sprains

A sprained ankle occurs when a sudden movement stretches the ligaments beyond their “normal” range of motion. Chronic ankle instability is a condition that may occur when the sprain fails to heal properly. It also strikes those who repeatedly sprain their ankle.

In this post, we look at the types of ankle sprains, what causes them, and how you can prevent them. We also discuss the dangers of repeated ankle sprains and why it’s so important to see a podiatrist.

What Is an Ankle Sprain?

Ankle sprains occur when a movement like turning or twisting your ankle damages one or more of the ligaments. Sprains are categorized according to the extent of damage to said ligament.

Sprains are further categorized by where they occur on the ankle. The most common type is the inversion ankle sprain. It occurs when the foot turns inward, stretching the ligaments on the outside of the ankle. You feel pain from this type of sprain on the outer ankle.

Damage to the inner ligaments cause an eversion ankle sprain, which occurs when the foot twists or turns outward. You feel this pain on the inside of your ankle.

What Is Chronic Ankle Instability?

Patients who have chronic ankle instability are prone to the outer ankle giving way or turning, even when just standing.

The most common causes of chronic ankle instability are an ankle sprain that does not heal properly and repeated ankle sprains.

And, while repeated sprains cause this instability, the condition also increases risk of repeated ankle sprains. And, of course, every sprain further damages and weakens the ligaments, worsening the condition and creating a nasty cycle.

Ankle Sprain Risk Factors & Prevention

Sprained ankles are usually the result of an awkward landing that causes your ankle to twist or turn unnaturally. Even though the injury is the result of an accident, certain activities increase your risk. Which means that you can also take steps to reduce your risk of sprain.

Since sprains are the leading cause of chronic ankle instability, you want to do everything you can to reduce your risk of sprain.

Why You Should Visit a Podiatrist for Ankle Sprains

The most common treatment for ankle sprains is rest, ice, compression, and elevation, commonly referred to as RICE. The simplicity of the treatment is why many people choose self-care over treatment from a podiatrist.

Unfortunately, this often leads to complications and a failure to heal properly. Complications may include:

When you visit a podiatrist to treat a sprained ankle, they conduct a full examination to determine the extent of damage to the ligament. This includes finding points of tenderness and testing range of motion in the affected ankle.

Your podiatrist may also order diagnostic imaging such as x-rays or an MRI. In addition to determining whether there’s any tearing to the ligament, your doctor is looking for broken bones.

How to Prepare for Your Appointment

Patients often feel nervous when talking to their doctor. That’s why we recommend creating a list of pertinent information and questions you’d like to ask.

Finally, create a list of all prescription and over-the-counter medications you take, including dosage. Your list should include supplements and vitamins.
