Inversion ankle sprains are one of the most common foot and ankle injuries—particularly among athletes and active individuals. Despite being common, these sprains can sideline you for weeks if not treated properly. At Yeargain Foot & Ankle, we treat countless ankle injuries and believe that understanding the mechanics behind them is key to prevention and fast recovery.
In this article, we’ll break down why inversion sprains occur, how they’re diagnosed and treated, and what you can do to avoid them in the future.
What Is an Inversion Ankle Sprain?
An inversion sprain happens when the foot rolls inward—often unexpectedly—causing the outer (lateral) ligaments of the ankle to overstretch or tear. This typically occurs during activities that involve rapid changes in direction, jumping, or uneven surfaces.
Did You Know? Over 90% of ankle sprains are inversion sprains, with the anterior talofibular ligament (ATFL) being the most commonly injured.
Why Are Inversion Sprains So Common?
Several factors make these sprains so prevalent:
- Ankle anatomy: The lateral ligaments are more exposed and less robust than the medial ones.
- Sports activity: Basketball, soccer, trail running, and similar sports involve fast pivots and landings that stress the ankle.
- Footwear: Unsupportive or worn-out shoes can fail to stabilize the foot.
- Previous sprains: A history of ankle injuries weakens ligaments and affects balance, increasing re-injury risk.
- Uneven terrain: Missteps on curbs, sidewalks, or hiking trails can roll the ankle inward in an instant.
Signs & Symptoms of an Inversion Sprain
Common symptoms include:
- Sudden, sharp pain on the outside of the ankle
- Swelling and bruising
- Tenderness when touched
- Difficulty bearing weight or walking
- A popping sound or sensation at the time of injury
If symptoms persist or worsen, it’s essential to seek care to avoid long-term instability or chronic pain.
How Inversion Sprains Are Diagnosed
At Yeargain Foot & Ankle, we conduct a thorough physical exam and may use digital imaging (X-rays or MRI) to determine the extent of the damage. Our goal is to identify whether the sprain is mild (Grade I), moderate (Grade II), or severe (Grade III) and develop a treatment plan accordingly.
Recovery & Treatment Options
Treatment depends on the severity of the sprain, but common approaches include:
RICE Method
- Rest, Ice, Compression, and Elevation help reduce swelling in the first 48–72 hours.
Ankle Bracing or Taping
To stabilize the joint during early recovery and prevent re-injury.
Physical Therapy
Supervised exercises to improve range of motion, strength, and balance are essential. We guide patients through custom rehab programs designed to prevent recurrence.
Advanced Care
For severe sprains, we may recommend regenerative medicine, guided injections, or minimally invasive surgery.

Preventing Future Sprains
To avoid repeat injuries, our podiatrists recommend:
- Wearing supportive footwear for your activity
- Balance and strength training, especially for the ankles and calves
- Stretching before exercise to improve flexibility
- Avoiding high-risk movements after a recent injury
We also offer custom orthotics to support proper foot alignment and reduce ankle strain.
