Figure 2

The impact of rod stiffness on the restoration of the thoracic kyphosis and the correction of the vertebral rotation. Scatter plot showing the correlation between restoration of the thoracic kyphosis against the patient's number for the whole study population (A), and for the patients operated with smaller rods with a diameter of 5.5 mm (B). Scatter plot showing the correlation between correction of the vertebral rotation against the patient's number for the whole study population (C), and for the patients operated with smaller rods with a diameter of 5.5 mm (D). Footnotes: VR indicates vertebral rotation. Correlation coefficinet = (A) 0.344, (B) 0.232, (C) 0.370, and (D) 0.174.
