A 43-year-old male patient falls from a height of 3 m. A preoperative lateral radiograph (a) showing right calcaneus fracture with reduced Böhler angle (9°), length (81.9 mm), and height (70 mm), and the preoperative horizontal (b, c) computed tomography image showed Sanders type IIA fracture with increased calcaneal width (39 mm). The Steinmann pin retractor (d, e) was used during the operation. Postoperative lateral (f, g) and axial (h) radiographs show obvious correction of the Böhler angle (34°), and improvements in calcaneal length (88.8 mm), height (77.5 mm), and width (33 mm). AOFAS score was 89 at the last follow-up
