What is a sprain?

Sprains occur when the ligaments are stretched more than normal resulting in a partial tear or complete tear of the ligament.

Ultimately there is a loss of stability at the joint.


Risk factors
Risk Factors

  • uneven ground

  • previous untreated ankle injuries

  • being overweight

  • poorly fitting or worn out shoes


Degree of severity
Degree of Severity

Grade I - ligaments stretched not actually torn

Grade II - partial tear

Grade III - most severe with ligament completely torn and a lot of joint instability


Ligaments providing stability
Ligaments providing stability

  • anterior talo-fibular ligament ATFL (goes from the talus to the fibula)

  • calcaneo-fibular ligament (goes from the calcaneus to the fibula)

  • posterior talo-fibular ligament PTFL (goes from the talus to the fibula).
