The posterior subtalar joint capsule encloses the posterior facet — the largest and most important subtalar articulation — reinforced by the posterior talocalcaneal ligament.

Region: Foot & Ankle
Biomechanics

Function & Actions

Encloses the posterior subtalar articulation, contains synovial fluid, and is disrupted in subtalar dislocations.

Clinical Relevance

Clinical Notes

Capsule tightness contributes to subtalar stiffness after calcaneal fracture. Subtalar arthroscopy addresses posterior compartment pathology through the posterior portal.
