What is an Ankle Sprain?
An ankle sprain occurs when the ligaments surrounding the ankle joint become overstretched or torn, usually as a result of twisting or rolling the ankle awkwardly. While ankle sprains are common injuries, affecting many people every year, it’s critical to understand that not all ankle sprains are identical in nature or severity. Generally, ankle sprains can be categorised into two main types: low ankle sprains and high ankle sprains. These differ significantly in how they occur, the tissues they affect, the symptoms they produce, and their respective treatment pathways.
Whether you’ve recently suffered an ankle injury or you’re just keen to learn more, knowing the differences between low and high ankle sprains makes all the difference in choosing appropriate management and avoiding complications down the line.
Low Ankle Sprain: The More Common Injury
A low ankle sprain, also known as a standard or lateral ankle sprain, is the most frequent kind of ankle injury, often happening to those playing sport or engaging in physical activities involving rapid direction changes. This injury typically occurs when the foot rolls inward—known medically as inversion—which places excessive stress on the ligaments located on the outer (lateral) aspect of the ankle.
Symptoms of a low ankle sprain vary according to severity but typically include immediate pain, swelling, bruising around the outer ankle, and trouble bearing weight or moving the foot comfortably.
Low ankle sprains can range from mild, where the ligaments are overstretched and painful, to severe, which involves partial or complete ligament tears. It’s common for people with a low ankle sprain to feel pain and instability, often finding walking difficult or uncomfortable immediately following the injury.
High Ankle Sprain: The Less Common but More Serious Injury
A high ankle sprain, medically referred to as a ‘syndesmotic’ ankle sprain, represents a more complex problem. Occurring less frequently, these sprains affect the ligaments situated above the ankle joint between the tibia (shinbone) and fibula. Unlike the low ankle sprain, high ankle sprains usually result from the foot twisting outward (external rotation) while the ankle is simultaneously forced upwards, a mechanism commonly seen in contact sports and skiing accidents.
High ankle sprains often present more subtle outward signs initially—in fact, athletes may underestimate their severity because significant swelling or bruising may take longer to appear compared to low ankle sprains. However, the pain, which can be quite sharp, typically occurs just above the joint and worsens when the ankle is rotated outward or when the injured individual tries to bear weight.
The high ankle sprain is usually considered a more serious injury, and recovery times are generally longer—commonly double or triple that of a more standard low ankle sprain, depending on severity.
Low vs High Ankle Sprain: Spotting the Key Differences
Understanding precisely whether you have a low or high ankle sprain considerably influences your healing pathway and return-to-activity timeline. Some key differences to bear in mind include:
- Mechanism of injury: Low ankle sprains generally involve inward rolling of the foot, while high ankle sprains involve outward rotation combined with upward force.
- Location of pain and swelling: Low ankle sprains typically cause swelling and bruising around the outside ankle area, whereas high ankle sprains often cause pain and swelling slightly higher up between the tibia and fibula.
- Severity and recovery: High ankle sprains are often more severe and require a longer recovery time due to the complexity and importance of the ligaments involved.
- Weight bearing and stability: While both injuries cause pain when weight bearing, a high ankle sprain tends to produce more instability and significant pain during rotational movements.
Treating Low Ankle Sprains: Managing the Most Common Ankle Injury
Fortunately, many low ankle sprains are treatable conservatively at home with basic self-care measures (commonly known as PRICE: Protection, Rest, Ice, Compression, Elevation). Ice packs, ankle braces, supports, and elevation of the ankle are usually sufficient interventions for mild to moderate cases.
For moderate to severe low ankle sprains, a healthcare professional may recommend physiotherapy to reinforce strength and stability through guided exercises. Rehabilitation therapy is key to preventing chronic symptoms or repeat injuries, which can arise if improperly healed ligament damage leaves the ankle vulnerable to further sprains.
Usually, recovery for mild low ankle sprains can range from one to three weeks, but severe cases involving torn ligaments can take several weeks or even months to fully heal.
Treating High Ankle Sprains: Special Considerations for Syndesmosis Injuries
Treatment options for high ankle sprains are typically more involved because of the injury’s increased complexity. During an initial evaluation, a medical professional will usually request imaging like an X-ray, ultrasound, or MRI to determine the severity of the ligament damage and rule out fractures.
Treatment will typically begin conservatively, similar to low ankle sprains. This includes immobilisation with a walking boot or special ankle support, protected weight bearing, pain relief medication, and physiotherapy focusing on gradual improvement in the ankle’s range of motion and stability over weeks or months.
In particularly severe or unstable high ankle sprains, surgery may sometimes become necessary. Surgical intervention generally involves using screws or suture devices to secure and stabilise the joint between the tibia and fibula, allowing the ligaments to heal properly.
Choosing the Right Walking Aid: When Might You Need Crutches?
For both types of ankle sprains, particularly high ankle sprains, temporary mobility aids like crutches or knee scooters are particularly useful. These aids prevent excessive weight bearing, reduce pain during recovery, and can prevent re-injury, providing much-needed support and accelerating healing times. If your healthcare provider recommends using a walking boot or cam walker, often crutches or similar aids will enable better support and healing during initial weeks after injury, particularly when severe ligament damage or instability is present.
When to Consult a Medical Professional
If you suspect you’ve suffered from either type of ankle sprain, particularly if you experience significant pain, swelling, inability to bear weight properly, or notable ankle instability, it’s always wise to seek medical attention promptly. A thorough clinical examination and possibly imaging studies will help determine the injury type and severity, guiding your recovery plan accordingly.
Delaying treatment or managing an ankle sprain incorrectly risks further damage or chronic ankle instability that can severely hinder your mobility and daily activities.
Final Thoughts: Healing Well and Preventing Future Injuries
Both low and high ankle sprains require careful attention to achieve the best possible recovery outcomes. Understanding their key differences, symptoms, and treatment approaches ensures you get back to daily activities or sports swiftly and safely, minimising the risk of ongoing or further injuries.
Remember, seeking professional medical guidance early, carefully observing instructions for rehab and recovery, and using appropriate supportive equipment like braces, boots, or crutches when necessary helps your ankle heal thoroughly, strong, and stable again—ready to handle life’s twists, turns, and adventures with confidence.
