Posterior Inferior Tibiofibular Ligament
Description
Names
- Posterior Inferior Tibiofibular Ligament (PITFL)
- Posterior ligament of the lateral malleolus
- Posterior tibiofibular ligament
- Posterior inferior ligament
- Superficial posterior inferior ligament
Gross Anatomy
- Origin: posterior tubercle of the tibia
- Run obliquely, distally, laterally 20-40° angle to the horizontal plane[2]
- Insert: posterior lateral malleolus
Function
- Forms a component of the Distal Tibiofibular Syndesmosis
- Works with anterior inferior tibiofibular ligament to hold fibula close in the fibular groove
- Responsible for 9% of total resistance to fibular displacement[3]
