MR imaging and multiplanar reconstruction were used to evaluate relative length of the spinal cord to the vertebral column in adolescent idiopathic scoliosis (AIS). ⋯ There was significantly reduced spinal cord to vertebral column ratios in the AIS patients with severe curve, suggesting a disproportional growth between the skeletal and the neural systems. The relative shortening and functional tethering of spinal cord may play an important role in the etiopathogenesis of AIS.

Cyclic mechanical stress (CMS) was applied to cultured nucleus pulposus and anulus fibrosus cells, and the production of inflammatory agents by these cells was evaluated. ⋯ The results of this study suggested that CMS might be involved in the pathomechanism of pain induction of lumbar disc diseases.

Validation of a translated, culturally adapted questionnaire. ⋯ The Spanish version of the FABQ has good comprehensibility, internal consistency, and reliability. It cannot be analyzed parametrically, but only nonparametrically. The total FABQ is at least as valid as its subscales and simpler to score, making it more suitable for routine clinical use.
