Posterior inferior tibiofibular ligament

The distal posterior inferior tibiofibular ligament (PITFL) is a strong ligament of the tibiofibular syndesmosis.

Gross anatomy

The posterior tibiofibular ligament is formed of multiple collagen bundles with interposed fatty tissue and courses obliquely downward from the posterior distal tibia to the posterior margin of the fibular, in a 20-40° angle to the horizontal plane. Proximally it blends with the posterior fibers of the interosseous ligament cranially. It has a triangular shape.

Attachments

• proximal attachment at the posterolateral Volkmann tubercle
• distally converging insertion at the small posterior fibular tubercle

Radiographic features

MRI

Hypointense in both T1 and T2 with interspersed fatty tissue.
