Biomechanical analysis. ⋯ The larger diameter screws were equivocal or significantly more resilient than the cement augmented standard diameter screws at the strongest of the insertion angles for all values. Since rigidity of the instrumentation construct is one of the very few factors that is surgeon controlled, this could influence the choice of instrumentation in revision spinal arthrodesis.

A retrospective case-control study. ⋯ Amicar was highly effective in decreasing perioperative blood loss and transfusion requirements in patients with neuromuscular scoliosis undergoing PSF and SSI. It was most effective in decreasing estimated intraoperative blood loss. This results in decreased transfusion requirements, costs, and potential transfusion-related complications.

Case series. ⋯ Apical convex rib head dislocation into the canal in NF-1 scoliotic patients can be suspected by conventional radiograms and be proven by CT and MRI. The rib dislocation is not a contraindication to deformity correction with modern spinal instrumentation techniques when preventive measures are applied.
-
Cross-sectional study. ⋯ There is a high prevalence of FJ OA in the community. Prevalence of FJ OA increases with age with the highest prevalence at the L4-L5 spinal level. At low spinal levels women have a higher prevalence of lumbar FJ OA than men. In the present study, we failed to find an association between FJ OA, identified by multidetector CT, at any spinal level and LBP in a community-based study population.

A retrospective study to review patients with acute thoracolumbar burst fractures who were conservatively treated. ⋯ Conservative treatment is safe and effective for selected patients with thoracolumbar burst fractures, even in some cases with neurologic deficit. The Load Sharing Classification could be used for guiding the treatment of thoracolumbar burst fractures not only in surgical approach choice but also in surgical decision-making.
