Sanders type III calcaneal fracture in a 47-year-old male. a Preoperative lateral axial radiograph of the calcaneus shows articular surface collapse. Böhler angle, − 46°; Gissane angle, 69°; calcaneal height, 27.81 mm; calcaneal length, 76.54 mm. b Preoperatively, the calcaneus is widened. Calcaneal width, 80.68 nm. c, d The articular surface has a comminuted fracture, and the middle mass of the bone is sunk into the calcaneus. e, f CT demonstrated calcaneal medial wall crush, and intercalary displacement of bone mass
