Thoracic hypokyphosis following AIS correction may be associated with reduced lumbar lordosis with potential adverse effects on the global sagittal balance. In the present study, we were interested in how the amount of thoracic kyphosis influences the sagittal profile and balance in selective thoracic (STF) and thoracolumbar fusions. ⋯ A critical thoracic kyphosis of 23° and more should be aimed for in hypokyphotic patients to potentially avoid post-operative sagittal plane deterioration with mechanical and likely also clinical consequences.

Dynamic contrast-enhanced (DCE)-MRI is used for examining the features of malignant tumours in radiology, and we can obtain more information in terms of the diffusion of the media over the course of time. The purpose of this study was to clarify the usefulness of DCE-MRI for distinguishing pyogenic spondylitis (PS) and tuberculous spondylitis (TB). ⋯ This study indicated that longer maximum contrast index, higher likelihood of diffusion pattern from the disc, and higher likelihood of enhanced disc are more specific to PS than TB. This less invasive imaging technique is useful for more accurate diagnosis of PS and TB. These slides can be retrieved under Electronic Supplementary Material.
