Comparative Study
Centralization: its prognostic value in patients with referred symptoms and sciatica.
Prospective, comparative cohort study. ⋯ Patients with sciatica and suspected disc herniation who have a centralization response to a mechanical evaluation will have significantly better outcomes. Patients who do not have centralization will be 6 times more likely to undergo surgery.

A prospective cross-sectional design was used to evaluate the Scoliosis Quality of Life Index (SQLI). SQLI is a 22-item self-reporting health-related quality-of-life questionnaire for idiopathic scoliosis patients. ⋯ SQLI is reliable and valid and demonstrates satisfactory distribution of scores. SQLI is a promising instrument in the assessment of AIS patients.

Randomized controlled trial. ⋯ The results indicate that the costs of this active back program are more than reimbursed as a consequence of earlier return to work.

Comparative Study
Facet tropism and interfacet shape in the thoracolumbar vertebrae: characterization and biomechanical interpretation.
Thoracolumbar facet and interfacet linear dimensions were measured and analyzed. ⋯ Facet tropism is a normal characteristic in humans, yet it varies along the thoracolumbar spine.

Retrospective case-controlled study of cervical laminoplasty. ⋯ Subaxial laminoplasty maintained the alignment. But if laminoplasty included the C2 lamina, the alignment worsened.
