A patient with a BMD T-score. a Preoperative X-ray examination revealed vertebral compression fracture at L1; the anterior vertebral body height was 23.3 mm and compressed 17.6 % and the central vertebral body height was 17.5 mm and compressed 38.2 %. Cobb angle was 18.2°. b Roenterography 1 week post surgery revealed that the anterior vertebral body height was 27 mm and was restored to 84.4 % of the original height and the central vertebral body height was 25.0 mm and was restored to 88.2 % of the original height. Cobb angle was 15.9°. Bone cement filling was adequate. c Roenterography at the final follow-up (8 months post surgery) revealed that the anterior vertebral body height was 26.8 mm and was restored to 83.8 % of the original height and the central vertebral body height was 24.4 mm and was restored to 86.1 % of the original height. Cobb angle was 16°. Bone cement filling was adequate
