Medial and lateral complex

• Anterior inferior tibiofibular

  -connect front tibia and fibula

  Post inferior tibiofibular

  -connect back to tibia and fibula 

  Transverse tibiofibular

  -connect medial sides of tibia and fibula

• deltoid lig 

  -anterior and posterior tibiotalar

  tibionavicular

  -connects tibia and navicular

  tibiocalcaneal

  -tibia and calcaneus

Syndesmosis

• Anterior inferior tibiofibular

  -connect front tibia and fibula

  Post inferior tibiofibular

  -connect back to tibia and fibula 

  Transverse tibiofibular

  -connect medial sides of tibia and fibula

• deltoid lig 

  -anterior and posterior tibiotalar

  tibionavicular

  -connects tibia and navicular

  tibiocalcaneal

  -tibia and calcaneus

lateral complex function

• stabilize the joint during eversion; preventing talar subluxation

• keep tibia and fibula together to create ankle mortise 

• limit ankle inversion and prevent inferior and lateral talus subluxation
