An ankle sprain is one of the most common musculoskeletal injuries, often occurring when the ligaments surrounding the ankle joint are stretched or torn due to sudden twisting or rolling of the foot. Understanding the causes, symptoms, and treatment options for a sprained ankle is essential for proper management and recovery from this injury.

Common Causes of Ankle Sprain
Many patients sprain an ankle when they slip and fall or while playing sports.
Sudden Movements
Ankle sprains frequently occur during activities that involve sudden changes in direction, such as sports like basketball, soccer, and tennis. Rapid movements, pivoting, jumping, or landing awkwardly can place excessive stress on the ligaments, leading to sprains.
Uneven Surfaces
Walking, running, or exercising on uneven or unstable surfaces increases the risk of ankle sprains.
Stepping on a curb, pothole, or an irregular surface can cause the ankle to roll or twist unexpectedly, resulting in injury.
Weak Ankles
Individuals with weak ankle muscles or poor proprioception (awareness of body position) may be more susceptible to ankle sprains. Weakness in the muscles and ligaments surrounding the ankle joint can compromise stability and increase the likelihood of injury.
Previous Injury
A history of previous ankle sprains or ankle instability predisposes individuals to recurrent sprains.
Inadequate rehabilitation and failure to address underlying weaknesses or imbalances after a previous sprain can contribute to future injuries.
Symptoms of a Sprained Ankle
Pain
Ankle sprains typically cause pain, which may range from mild to severe depending on the severity of the injury. Pain is usually felt along the outer (lateral) aspect of the ankle and may worsen with weight-bearing or movement.
Swelling
Swelling around the ankle joint is a common symptom of sprains and may develop rapidly following the injury. Swelling occurs due to inflammation and fluid accumulation in the injured tissues.
Bruising
Bruising or discoloration of the skin may occur around the ankle due to blood vessel damage and leakage of blood into the surrounding tissues. Bruising may become more apparent in the days following the injury.
Limited Range of Motion
Ankle sprains can impair the affected joint’s normal range of motion and flexibility. Individuals may experience difficulty moving the ankle or bearing weight on the injured foot.
Instability
Ankle instability or a feeling of “giving way” may be present, especially with more severe sprains or injuries involving complete ligament tears.
Treatment for an Ankle Sprain
R.I.C.E. Protocol
- Rest: Avoid activities that exacerbate pain and inflammation, and allow the injured ankle to rest.
- Ice: Apply ice packs to the injured area for 15-20 minutes several times a day to reduce swelling and pain.
- Compression: Use compression bandages or wraps to provide support and minimize swelling.
- Elevation: Elevate the injured ankle above the level of the heart to reduce swelling and promote drainage of excess fluid.
Pain Management
Over-the-counter pain medications such as ibuprofen or acetaminophen can help alleviate pain and discomfort. Topical analgesic creams or gels may also provide temporary relief.
Immobilization
Depending on the severity of the sprain, immobilization with a brace, splint, or walking boot may be necessary to stabilize the ankle and promote healing. Crutches may be used to prevent weight-bearing on the injured ankle during the initial stages of recovery.
Physical Therapy
Once pain and swelling have subsided, physical therapy exercises and rehabilitation programs can help restore strength, flexibility, and proprioception in the ankle. Exercises focus on improving range of motion, strengthening muscles, and enhancing balance and stability.
Gradual Return to Activity
Gradually reintroduce weight-bearing activities and sports-specific movements as the ankle heals and strength improves. Progression should be gradual to minimize the risk of re-injury and allow adequate time for tissue healing.
Surgical Intervention
In cases of severe ankle sprains with significant ligament damage or instability, surgical intervention may be necessary to repair or reconstruct the injured ligaments. Surgery is typically reserved for cases that do not respond to conservative treatment or for individuals with recurrent ankle instability.
Conclusion
Ankle sprains are common injuries characterized by stretching or tearing of the ligaments surrounding the ankle joint. Prompt recognition and appropriate treatment are essential for optimal recovery and prevention of long-term complications.
