From: Can preoperative magnetic resonance imaging be used for sagittal kyphotic flexibility assessment in patients with kyphosis secondary to symptomatic old osteoporotic thoracolumbar fracture?

A RKAs measured on standing radiographs, supine MRI, and intraoperative prone radiographs were 48.0°, 34.4°, and 32.0°. Compared with the RKA measured in standing position, the RKA measured on supine MRI decreased by 13.6° (95% confidence interval 11.4°–15.8°), whereas the RKA measured on intraoperative prone radiographs decreased by 16.1° (95% confidence interval 13.7°–18.5°). B Graph showing the linear dependency between SK flexibility measured on magnetic resonance imaging (MRI) (horizontal axis) and on Intraoperative radiograph (IR) (vertical axis). IR flexibility is on average 2.4° higher than flexibility of sagittal kyphosis curve on MRI (R.2 = 0.912, p < 0.001)
