Result: The endplate fractures occurred in 10 out of 46 intervertebral discs (22%) and the pedicle fracture occurred in 4 cases (3.3%) of 120 pedicles. The average correction angle of the convex group was 5.7 °, and the average correction angle of the concave group was 2.7 ° (p <0.001). The incidence of endplate fractures was 6 in 19 (32%) in the convex group and 3 out of 22 (14%) in the concave group (p >0.05). The incidence of pedicle fractures was 3 in 58 pedicles (5.2%) in the convex group and 1 in 62 pedicles (1.6%) in the concave group (p >0.05). The average correction angle for the HW group was 5.8 °, and the average correction angle for the LW group was 3.0 ° (p <0.01). The endplate fractures were 6 of 14 (43%) in the HW group and 4 of 32 (13%) in the LW group (p=0.046). Pedicle fractures occurred in 1 of 54 pedicles (1.9%) in the HW group and 3 of 66 pedicles in the LW group (4.5%) (p >0.05).
