Anatomy

The lateral ligament complex of the ankle is composed of three ligaments: the anterior talofibular ligament (ATFL), the calcaneofibular ligament (CFL) and the posterior talofibular ligament (PTFL).

Mechanism of Injury

  • A lateral ankle sprain frequently occures when a plantar-flexed ankle is inverted, completely rupturing one or more of the lateral ligaments.
  • A medial ankle sprain may occur when the foot is everted and externally rotated.

Symptoms

Tear of the AFTL:

  • Pain is felt on weightbearing and ankle motion
  • Swelling and tenderness occur anterior (front) to the lateral malleolus
  • Effusion of blood later results in a hematoma, with bruising and skin discolouration around and distal to the injury
  • Instability

Tear of the CFL

  • Swelling and tenderness occur over the injured ligament, distal to the lateral malleolus.
  • Pain is felt during weightbearing and when moving the ankle joint.

Effusion of blood causes hematoma and bruising behind and below the lateral malleolus.
