Posterior talar process fractures may involve medial or lateral tubercle of the posterior process of talus. The posterior talofibular ligament attaches on the lateral tubercle and flexor hallucis longus runs between these tubercles. Unfused ossification center of the lateral tubercle forms the os trigonum.

Terminology

A Shepherd fracture refers to a fracture of the lateral process. An elongated lateral tubercle of the posterior process of the talus is referred to as a Stieda process, so occasionally these fractures are described as Stieda process fractures.

A Cedell fracture is a fracture of the medial process.

Pathology

Mechanism of injury

injury to lateral tubercle is caused by inversion or extreme equinus
injury to medial tubercle is uncommon and is caused by forced dorsiflexion and pronation

Treatment and prognosis

Short leg cast or ankle brace is used until signs of union appear. If there is non-union, then excision of the fragment is undertaken.
