Key Takeaways
- An ankle sprain occurs when the ligaments supporting the ankle are stretched or torn, but not every twisted ankle is a sprain.
- Severe pain, significant swelling and difficulty bearing weight may indicate a more substantial injury, including a fracture.
- Being able to walk does not necessarily rule out a fracture or significant ligament damage.
- Early assessment can help identify the injury and determine appropriate management.
- Recovery depends on the extent of the injury, rehabilitation and individual circumstances.
Why Does a Twisted Ankle Sometimes Turn Out to Be More Than a Sprain?
You step off a kerb awkwardly, land incorrectly after a jump or twist your foot while playing badminton. Within minutes, your ankle starts swelling.
Most people assume it is a simple sprain. However, a similar twisting movement can cause different injuries, ranging from mild ligament stretching to a fracture.
An ankle sprain happens when the ligaments, which connect bones and stabilise the joint, are stretched beyond their normal limits or torn. The severity varies depending on the extent of the damage.
Other possible injuries include,
- Ankle fractures- A break in one or more of the bones forming the ankle joint.
- High ankle sprains- Injuries involving the ligaments connecting the two lower leg bones, usually above the ankle joint.
- Tendon injuries- Damage to structures that help move and stabilise the foot and ankle.
This is why the mechanism of injury, pain location and physical examination all matter.
Which Symptoms Suggest Something More Serious?
Swelling and bruising are common after ankle sprains. However, certain symptoms warrant closer attention. You should consider seeking medical assessment if you experience,
- Severe or persistent pain- Particularly around the ankle bones rather than just the surrounding soft tissues.
- Difficulty bearing weight- Being unable to take four steps after the injury is a reason to consider an X-ray assessment.
- Significant bruising- Extensive discolouration may accompany more substantial tissue damage.
- Unusual ankle positioning- Visible deformity may indicate a fracture or dislocation.
- Numbness or tingling- These symptoms may suggest nerve involvement or another complication.
An inability to bear weight, obvious deformity, an open injury or a foot that becomes cold, pale or blue requires urgent medical attention.
One common misconception is that walking means the ankle is not fractured. This is not necessarily true. Some fractures allow limited movement or weight-bearing.
How Can Your Doctor Tell the Difference?
Symptoms alone cannot reliably distinguish every ankle sprain from a fracture. An orthopaedic assessment generally considers,
- How the injury happened, including whether the ankle rolled inwards or outwards.
- The precise location of tenderness.
- The degree of swelling and bruising.
- Ankle movement and stability.
- Whether weight-bearing is possible.
An X-ray may be recommended when a fracture is suspected. MRI or other imaging may be considered when there is concern about ligament, tendon or other soft tissue damage that requires further investigation.
What Does Ankle Sprain Treatment Involve?
The appropriate ankle sprain treatment depends on the structures affected and the severity of the injury. For many uncomplicated sprains, initial management may include,
- Protection- Avoid activities that worsen the injury.
- Relative rest- Reduce weight-bearing when painful, using support if necessary.
- Ice- Apply a wrapped cold pack for short periods to help manage pain and swelling.
- Compression- A suitable bandage may help control swelling.
- Elevation- Keep the ankle raised when resting.
As symptoms improve, guided movement and physiotherapy can help restore flexibility, strength and balance. More substantial injuries may require a brace, temporary immobilisation or other interventions. Surgery is considered in selected cases rather than being necessary for every severe sprain.
FAQs
How long does an ankle sprain take to heal?
Recovery varies. Mild sprains may improve within a few weeks, while more significant ligament injuries can take several months. Rehabilitation and the severity of the injury influence recovery.
Should I walk on a swollen ankle?
Avoid forcing yourself to walk through significant pain. Reduce weight-bearing initially and seek assessment if walking is difficult or symptoms are concerning.
Can an ankle sprain heal without physiotherapy?
Some mild sprains recover with appropriate home care. However, rehabilitation may be recommended to restore strength, movement and balance, particularly after more significant injuries.
Can I exercise once the ankle pain disappears?
Not necessarily. Pain relief does not always mean the ankle has regained its strength and stability. Returning to sports should depend on movement, strength, balance and functional recovery.
Can an old ankle sprain cause problems later?
Yes. Some people experience recurring instability, discomfort or repeated sprains following an earlier injury, particularly if rehabilitation was incomplete.
Schedule a Consultation to Have Your Ankle Assessed
A twisted ankle is not always a minor injury, and overlooking a fracture or significant ligament damage can affect subsequent recovery.
If you have sustained an ankle injury and are unsure about its severity, an orthopaedic assessment can help clarify the underlying problem and appropriate management options.
At MASH Spine & Orthopaedics, Dr. MASH provides orthopaedic consultations for musculoskeletal concerns, including ankle injuries. Consider arranging a consultation to discuss your symptoms, assessment requirements and possible treatment approaches.
