Comparative Study
A comparison of the lenke and king classification systems in the surgical treatment of idiopathic thoracic scoliosis.
Retrospective case control study. ⋯ At intermediate follow-up, there does not seem to be significant radiographic or patient reported differences whether fusion levels are in agreement, longer, or shorter than those recommended by the Lenke or King classification systems.

Prospective clinical series with comparison to retrospectively collected data. ⋯ The critical ratio correlates more closely with the presence or absence of postoperative symptoms than measures of hematoma volume, and is consistent with the clinical expectation that greater thecal sac compression may result in more severe symptoms. Few guidelines exist for postoperative lumbar MRI interpretation. The critical ratio is an important contribution.

Circumspinal decompression with dekyphosis stabilization was prospectively performed with thoracic myelopathy due to ossification of posterior longitudinal ligament (OPLL). Neurologic outcome was reviewed. ⋯ The OPLL plaque in the thoracic spine might be most easily, safely, and completely removed or floated, and the spinal cord is circumferentially decompressed through circumspinal decompression with dekyphosis stabilization.

A modified Delphi study conducted with 28 experts in back pain research from 12 countries. ⋯ These definitions provide standards that may improve future comparisons of low back pain prevalence figures by person, place and time characteristics, and offer opportunities for statistical summaries.
