Conditions
Ankle sprain
An ankle sprain is an injury to the ligaments that stabilise the joint, almost always those on the outer side, when the foot rolls inwards. Most recover well with functional treatment: control of pain and swelling, early protected weight-bearing and balance exercises. A poorly rehabilitated sprain can leave an unstable ankle that keeps giving way. Dr Julio De la Morena grades the injury with ultrasound in the same appointment at Hospital Memorial Publio Cordón (Pozuelo de Alarcón, Madrid).
When to see a doctor
- You cannot put weight on the foot or take four steps.
- Significant swelling or extensive bruising.
- Pain that has not improved after one or two weeks.
- Repeated sprains or a feeling that the ankle gives way.
Diagnosis
The examination determines which ligaments are affected and whether an X-ray is needed to rule out a fracture. Ultrasound shows the state of the ligament and grades the injury, which guides recovery times.
Treatment
- First days: ice, elevation, compression and protection of the ankle.
- Early weight-bearing with a brace or functional taping, avoiding long immobilisation.
- Balance and strength exercises to restore stability and prevent re-injury.
- Chronic instability: a specific programme and, if it does not work, surgical assessment.
Frequently asked questions
Ice or heat for an ankle sprain?
Ice in the first few days, while there is swelling, for about 15 minutes and never directly on the skin.
Does an ankle sprain need a cast?
In the vast majority of cases, no. Functional treatment with early protected weight-bearing works better. Immobilisation is reserved for severe injuries and short periods.
When can I return to sport after a sprain?
It depends on the grade: from one or two weeks for mild sprains to several weeks for severe ones. More than time, what matters is recovering strength and balance before returning.
