Ankle Sprain
Mild
Ankle sprain is an injury in which one or more ligaments supporting the ankle are stretched or torn. It commonly occurs when the foot twists inward, producing an inversion injury that affects the ligaments on the outer side of the ankle. Sprains range from mild stretching to complete ligament tears. Typical symptoms include pain, swelling, bruising, tenderness, and difficulty bearing weight. Recovery varies with severity, and some severe injuries may require immobilization or further treatment.

When to Seek Medical Attention
Most ankle sprains are not emergencies and improve with appropriate treatment. Seek medical assessment when swelling, pain, or difficulty bearing weight is significant or does not improve. Prompt evaluation is important when there is severe deformity, inability to bear weight, numbness, loss of circulation, or concern for a fracture or major ligament injury.

Overview

Causes 1
An ankle sprain usually occurs when the ankle is forced beyond its normal range of motion. A sudden inward twisting movement is a common mechanism, especially during running, jumping, sports, or an unexpected step on an uneven surface. The supporting ligaments may be stretched, partially torn, or completely torn. Previous ankle injury can also contribute to recurrent sprains because weakness or instability may remain after an earlier injury.
Sedentary Lifestyle
Risk Factors
Risk factors include sports and activities involving running, jumping, rapid changes of direction, or uneven surfaces. Previous ankle sprains can increase the risk of another injury when strength and stability have not fully recovered. Poorly fitting footwear, inadequate conditioning, and returning to demanding activity before rehabilitation is complete may also increase risk. Reduced ankle strength, balance, or flexibility can make it harder to control the joint during sudden movements.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is usually based on the injury mechanism, symptoms, and physical examination. The clinician checks swelling, bruising, tenderness, range of motion, joint stability, and the ability to bear weight. X-rays may be needed when a fracture is suspected. MRI or other imaging may be considered when a significant ligament injury, persistent symptoms, or another structural problem is suspected. The severity of the sprain is assessed to guide protection, rehabilitation, and return to activity.
Prevention
Key Prevention Tips
Proper footwear and gradual conditioning can reduce the likelihood of ankle sprains
Warming up before sports, strengthening the muscles around the ankle, and improving balance and coordination can improve joint control
Activities should be increased progressively rather than suddenly
After an ankle injury, completing rehabilitation and restoring strength and stability before returning to demanding sports can reduce recurrence
People with repeated sprains may benefit from additional support such as bracing when recommended by a healthcare professional
Prevention Guidance
Proper footwear and gradual conditioning can reduce the likelihood of ankle sprains. Warming up before sports, strengthening the muscles around the ankle, and improving balance and coordination can improve joint control. Activities should be increased progressively rather than suddenly. After an ankle injury, completing rehabilitation and restoring strength and stability before returning to demanding sports can reduce recurrence. People with repeated sprains may benefit from additional support such as bracing when recommended by a healthcare professional.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
