Subtype A₁ intra-articular calcaneal fracture, calcaneal radiographs showed burst of lateral calcaneal wall (U) and bending fracture fragment (E) created incongruent posterior subtalar joint (2 pictures above). CT images showed that subtype A₁ comprised type A sustentacular fragment (SFA) and entire posterior calcaneal facet (PCF) had intact articular surface (I) and associated with bending fragment of calcaneal body by its articular surface was anterior surface of the bending fragment (2 pictures middle). Percutaneous reduction and 2 screw fixations of the bending fragment were performed (2 pictures below). Pre- and postoperative calcaneal fracture scores improved from 8 to 1 points.
