What is a sprained ankle?
A sprained ankle happens when you injure one or more of the ligaments around your ankle joint. Ligaments are bands of fibrous tissue that connect one bone to another and support your joints. You can get an ankle sprain when you twist your foot beyond its normal motion. This can stretch or tear the ligaments that support your joint.
On the outside of the ankle lie the lateral ligaments, which are the most frequently injured in an ankle sprain. These include the:
- anterior talo-fibular ligament (ATFL)
- calcaneofibular ligament (CFL)
- posterior talo-fibular ligament (PTFL)
What causes a sprained ankle?
Ankle sprains can occur simply by rolling your ankle on some unstable ground. Common examples of this occur when awkwardly planting your foot when running, landing unbalanced from a jump or stepping onto an irregular surface.

These injuries can also cause significan pain so the first steps to treatment wil be pain management. With the correct treatment and rehabilitation normal function should resume. Treatment includes
