Multicenter Study
Predictors of outcome in patients with chronic back pain and low-grade spondylolisthesis.
Retrospective case series. ⋯ This investigation, although limited by a number of factors including small sample size and retrospective, unblinded review, suggests that active worker's compensation and litigation issues are associated strongly with poor results of operative management for chronic low back pain in adult patients with low-grade spondylolisthesis.

To examine the impact of preinjury job perceptions on chronic pain patients (CPPs) return to work after pain facility treatment. ⋯ There is a relationship between preinjury job perceptions and actual return to work after pain facility treatment. Voiced "intent" not to return to the preinjury type of job is highly predictive of not returning to work after pain facility treatment.

The aim of this study is to assess the ability of conventional lumbar spine magnetic resonance imaging (MRI) to demonstrate the pars interarticularis. The right and left L4 and L5 pars in 50 patients undergoing lumbar spine MRI for low back pain, with or without radiculopathy, were assessed and classified into four types. ⋯ The gold standard was set by the consensus opinion of two consultant musculoskeletal radiologists on the available plain radiographs of the lumbar spine. MRI was found to have a sensitivity of 57% to 86%, specificity of 81% to 82%, positive predictive value of 14% to 18% and negative predictive value of 97% to 99% for the diagnosis of a pars defect.

Pain perception is a complex psychosomatic phenomenon and is influenced by different psychological variables. Apart from their pain perception, chronic pain patients also suffer from different bodily complaints. The clinical significance of this finding is not yet clear. Bodily complaints in chronic pain patients may represent (a) a bodily expression of depressive symptoms, (b) a sign of chronicity, and (c) the expression of a heightened bodily awareness in the sense of hypochondriasis. ⋯ From a cognitive-behavioral perspective the results support the hypothesis that psychological disturbance in chronic pain is a cause of long-standing pain perception and the result of the chronification process.
