Schmorl's nodes: common, highly heritable, and related to lumbar disc disease.
Schmorl's nodes (SN) are common, but little is known of their relationship with degenerative change and back pain or genetic and environmental factors influencing their expression. We studied healthy female twin volunteers to determine the prevalence and clinical features associated with SN. ⋯ SN are common in middle-aged women and are strongly genetically determined. They are associated with lumbar degenerative change, which is a risk factor for back pain, but are not themselves an independent risk factor for back pain.

Randomized Controlled Trial Multicenter Study
Physiotherapist-directed exercise, advice, or both for subacute low back pain: a randomized trial.
Advice and exercise are widely recommended for subacute low back pain, but the effectiveness of these interventions is unclear. ⋯ In participants with subacute low back pain, physiotherapist-directed exercise and advice were each slightly more effective than placebo at 6 weeks. The effect was greatest when the interventions were combined. At 12 months, the only effect that persisted was a small effect on participant-reported function. AUSTRALIAN CLINICAL TRIALS REGISTRY REGISTRATION NUMBER: 12605000039684.

Reported here is the treatment of severe axial discogenic pain in a young man utilizing the new minimally invasive transdiscal radiofrequency technique called intradiscal biacuplasty (Baylis Medical Inc., Montreal, Canada). The new procedure is detailed and step-by-step fluoroscopic imaging presented. ⋯ Visual analog scale pain score decreased from 5 to 1 cm at 6-month follow-up, Oswestry disability scores improved from 14 (28% or moderate disability) to 6 points (12% or minimal disability) and SF-36-PF (physical function) score changed from 67 to 82. Potential advantages of cooled, bipolar radiofrequency to heat the posterior annulus are discussed.

Psychosocial variables are acknowledged predictors of back disability, but multivariate studies are needed to understand their independent and overlapping effects. The objective of this prospective cohort study was to evaluate independent and shared associations of psychosocial variables on work status after first onset of low back pain (LBP) in working men. ⋯ After first onset of men with subacute LBP, self-reported pain intensity and functional limitation account for most of the variance in work status explained by psychosocial factors; however, the resulting disability can be accompanied by mild to moderate mood symptoms. This suggests that interventions to improve function, if commenced early in the course of subacute pain, might prevent work disability.

To determine which literature-based definitions of low back pain (LBP) could be combined to produce sufficiently similar sets for use in a meta-analysis. ⋯ In a research area that currently lacks uniformly accepted definitions of outcomes, we successfully used a Delphi consensus process to reach substantial agreement on combinable LBP outcomes that would be combinable for a meta-analysis.
