Prospective inception cohort study. ⋯ Patients with chronic LBP had more fear-avoidance beliefs for work than patients with acute LBP. There were small changes in fear-avoidance beliefs during the year of follow-up, except for a rapid decrease during the first month in the FABQ-PA in the acute sample. Fear-avoidance beliefs predicted pain and disability at 12 months after adjusting for socio-demographic and pain variables. Distress was a stronger predictor than fear-avoidance beliefs.

Presented is a case series of 3 patients, all of whom developed neurologic deficits due to cord or cauda equina compression during elective extremity surgery. ⋯ Spontaneous neural injury is rare but can occur to the anesthetized patient. Neurologic examination should be routinely performed in the recovery room; and if significant neurologic deficits are seen, investigative workup should not be delayed. If an intraspinal lesion is identified, immediate decompression may offer favorable results. Neurologic deficits should not be dismissed as peripheral palsies without careful evaluation.

Review Meta Analysis
The McKenzie method for low back pain: a systematic review of the literature with a meta-analysis approach.
Meta-analysis of randomized controlled trials to evaluate the effectiveness of the McKenzie method for low back pain (LBP). ⋯ There is some evidence that the McKenzie method is more effective than passive therapy for acute LBP; however, the magnitude of the difference suggests the absence of clinically worthwhile effects. There is limited evidence for the use of McKenzie method in chronic LBP. The effectiveness of classification-based McKenzie is yet to be established.

Immunohistochemistry for tumor necrosis factor (TNF) and protein gene product (PGP) 9.5 in vertebral endplates of patients with discogenic low back pain and Modic Type 1 or Type 2 endplate changes on MRI. ⋯ The results suggest that endplate abnormalities are related to inflammation and axon growth induced by TNF. TNF expression and PGP 9.5-positive nerve in-growth in abnormal endplates may be a cause of low back pain.

Retrospective analysis of our experience with os odontoideum at the Children's Hospital of Philadelphia. ⋯ Our data supports two separate etiologies for the os odontoideum: post-traumatic and congenital. The data should raise awareness that some children with preexisting syndromes may develop os odontoideum without previous trauma.
