A population-based, prospective cohort. ⋯ Emotional distress is a predictor for low back disability in persons with earlier LBP, but not in persons without. To prevent low back disability, emotional distress should be considered and treated in persons with LBP.
-
In vitro biomechanical flexibility experiment studying 5 sequential conditions. ⋯ Direct fixation of the pars ineffectively limits flexion and extension after a Type II hangman's fracture. If pars screw fixation can be achieved, posterior C2-C3 fixation more effectively stabilizes a hangman's fracture than anterior cervical plating.
-
A retrospective evaluation of anterior instrumentation of the vertebral bodies in the thoracolumbar spine. ⋯ There is adequate space anteriorly in the vertebral body, above and below the segmental vessels, for the insertion of one screw, even with staples.

Immunohistochemical and behavioral study using rat models of lumbar disc herniation and cauda equina syndrome. ⋯ Our findings suggest that activated p38 may play an important role in the involvement of microglia in the pathophysiology of pain following lumbar disc herniation and mechanical hypoalgesia, and motor nerve dysfunction of cauda equina following SCS.
