A 43-year-old male patient falls from a height of 4 m, over 10 years of smoking history. Preoperative lateral (a) and axial (b) radiograph showed bilateral calcaneus fracture with reduced Böhler angle (L: 2°, R: 5°), length (L: 80 mm, R: 75 mm), and height (L: 70 mm, R: 68 mm), and width (L: 44 mm, R: 42 mm). The preoperative horizontal computed tomography image (c) showed Sanders type IIIAC fracture. Steinmann pin retractor-assisted reduction with circle plate fixation via the sinus tarsi approach was used (d). Postoperative lateral (e) and axial (f) radiographs show obvious correction of the Böhler angle (L: 30°, R: 36°), and improvements in calcaneal length (L: 88.1 mm, R: 85 mm), height (L: 82.8 mm, R: 82.6 mm), and width (L: 36.2 mm, R: 36.9 mm). AOFAS score was 87 for left and 82 for right at the last follow-up
