A prospective observational study. ⋯ This observational study with magnetic resonance imaging and histology showed that muscle degeneration was more common on the concave side in patients with DLS. Radiculopathy and spinal deformity may contribute to the PVM degeneration.
-
A propensity score-matched case-control study. ⋯ This study demonstrates that patients with acute postoperative deep wound infections after instrumented lumbar spinal fusion have improved outcome measures after surgery but have greater back pain and a decreased probability of achieving minimum clinically important difference.

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.

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.
