Figure 1 (A) The angle of posterior convexity of the injured vertebra is measured as the angle between the line of the inferior endplate of the superior body of the injured vertebra and the line of the inferior endplate of the injured vertebra when the superior endplate of the injured vertebra is collapsed, (B) or the angle between the line of the superior endplate of the inferior body of the injured vertebra and the superior endplate of the injured vertebra when the inferior endplate of the injured vertebra is collapsed. (C) The vertebral height loss rate=(1-anterior vertebral height/posterior vertebral height)×100%. (D) The localized kyphotic Cobb angle is the angle between the upper endplate of the upper vertebra and the lower endplate of the lower vertebra. (Photo taken by iPhone 13, Apple).
