We compared the sizes of the dural sac among conventional magnetic resonance imaging (MRI), axial loaded MRI, and upright myelography in patients with lumbar spinal canal stenosis (LSCS). ⋯ The axial loaded MRI demonstrated a significant reduction in the dural sac size and significant correlations of the dural sac diameters with the upright myelogram. Furthermore, the axial loaded MRI had higher sensitivity and specificity than the conventional MRI for detecting the severe constriction observed in the myelogram. Therefore, the axial loaded MRI can be used to represent positional changes of the dural sac size detected by the upright myelography in patients with LSCS.

A retrospective study. ⋯ Both CWO and COWO are safe and effective surgical methods for correction of thoracolumbar kyphosis. COWO can obtain larger correction and better sagittal alignment without additional neurological complications.

A retrospective clinical analysis of patients operated on for spinal tumors. ⋯ This study demonstrates that monitoring beyond tumor resection is of essential importance in order to detect all critical phases of surgical procedure and to counteract accordingly.

Randomized Controlled Trial Comparative Study
A randomized controlled trial on the effectiveness of a classification-based system for subacute and chronic low back pain.
A randomized controlled trial. ⋯ The classification-based system used in this study was not effective for improving physical therapy care outcomes in a population of patients with subacute and chronic low back pain.

Multicenter Study
Which Lenke 1A curves are at the greatest risk for adding-on... and why?
Multicenter review of prospectively collected data. ⋯ Understanding the difference between Lenke 1A-L and 1A-R curve types may be helpful in preventing the adding-on phenomena postoperatively. To prevent adding-on in 1A-R curves, we recommend fusing distally to 1 level above the neutral vertebra or 1 to 2 levels above the stable vertebra. In 1A-L curves, adding-on may simply be a need to balance some lumbar curve progression in a young, skeletally immature patient.
