Ankle Sprain

An ankle sprain is an injury that occurs when the ligaments supporting the ankle joint are stretched or torn. Ligaments are strong, fibrous tissues that connect bones to each other and stabilize joints.

Acute vs. Chronic Ankle Sprains

Acute Ankle Sprain: This occurs suddenly, often due to a specific incident such as a fall or a sudden twist. It is particularly common during sports that involve side-to-side movement, such as tennis and basketball, or when walking on uneven ground.

Chronic Ankle Sprain / Chronic Ankle Instability: This happens when an acute sprain is not properly treated or when the ankle continues to be stressed. Chronic sprains are characterized by recurrent pain and instability, even after the initial injury has healed. Recurrent symptoms are due to structural impairment where the ligaments did not heal properly, leading to functional instability. Patients may experience a sensation of their ankles giving way intermittently.

Types of Ankle Sprains and Mechanism of Injury

Inversion Sprain

The most common type, where the ankle rolls outward and the foot turns inward, overstretching or tearing the lateral ligaments, leading to damage to the lateral (outside) ligaments of the ankle.

Eversion Sprain

The ankle rolls inward and the foot turns outward, affecting the medial (inside) ligaments of the ankle.

High Ankle Sprain

Typically caused by rotational forces or trauma, like when the foot is planted and twisted, which affects the syndesmotic ligaments above the ankle; less common but often more severe.

Signs and Symptoms of Ankle Sprains

Pain: Around the ankle, which may be immediate and severe or gradually worsening.
Swelling: Often noticeable around the affected area.
Bruising: Mainly in acute cases, may appear a few hours to days after the injury.
Tenderness: Especially when touching the injured area.
Limited Range of Motion: Difficulty moving the ankle.
Instability: Feeling of the ankle "giving way," particularly in chronic sprains.

Risk Factors of Ankle Sprains

Previous Ankle Injuries: A history of ankle sprains increases the likelihood of re-injury.
Weak or Imbalanced Muscles: Insufficient muscle strength or muscle imbalances can contribute to ankle instability.
Inappropriate Footwear: Shoes that lack adequate support can increase the risk of ankle sprains.
Physical Activity: Participating in high-impact sports or activities on uneven surfaces without proper warm-up or conditioning can elevate the risk.
Age: Older adults may experience reduced ligament strength and flexibility, making them more susceptible to ankle injuries.

Treatment and Management of Ankle Sprains

For Acute Cases:

Rest and Ice: To help with swelling and inflammation reduction.
Compression: Use an elastic bandage to help control swelling.
Elevation: Keep the ankle elevated above heart level to reduce swelling.
Rehabilitation Exercises: Once the acute phase has passed, gentle stretching and strengthening exercises can aid recovery and prevent future sprains.
Supportive Devices: Using ankle braces or supports during recovery can help stabilize the joint. For severe symptoms and difficulty bearing weight, an immobilization walking boot may be necessary.
Shockwave Therapy: For healing stimulation and quicker recovery.

For Chronic Cases:

Custom Foot Orthotics: To improve foot alignment and enhance joint stability.
Ankle Foot Orthotics: Offer extra structural support to help manage recurrent ankle instability, particularly in severe cases.
Shockwave Therapy: For healing stimulation.
Rehabilitation Exercises and Balance Training

For severe or complex cases, surgical intervention may be necessary. Therefore, it is crucial to consult a podiatrist for a comprehensive assessment of your ankle following a sprain. This will ensure an accurate evaluation of the injury's severity and the appropriate management and treatment plan.
