Immunohistological analysis of dichotomizing sensory nerve fibers projecting to the lumbar multifidus muscles and intervertebral disc (IVD), facet joint (FJ), or sacroiliac joint (SIJ) in rats. ⋯ Our results document the presence of dichotomizing sensory nerve fibers projecting to lumbar multifidus muscles and to IVDs, FJs, and SIJs. Referred low back muscle pain may reflect disorders of lumbar posterior structures, such as FJs and SIJs, rather than disorders of lumbar anterior structures, such as IVDs.

Randomized Controlled Trial
The efficacy of systematic active conservative treatment for patients with severe sciatica: a single-blind, randomized, clinical, controlled trial.
Prospective single-blind, randomized, clinical, controlled trial. ⋯ Active conservative treatment was effective for patients who had symptoms and clinical findings that would normally qualify them for surgery. Although participating patients had greater faith in the sham exercises before treatment, the symptom-guided exercises were superior for most outcomes.

Prospective radiographic and clinical analysis. ⋯ After primary surgery for adult scoliosis, frontal radiographic parameters did not correlate with HRQOL measures. In univariate analysis, patient age, SVA, and PT correlated with activity scores, although the correlation coefficients did not reach high values. After multivariate analysis, SVA was not a predictor of function.

Case report. ⋯ The treatment option achieved instant reduction, decompression, and fixation. A new treatment option for this type of injury is recommended.

A retrospective-cohort investigation (N = 245) utilizing a review of patient medical records and costs accrued through the Workers' Compensation Fund of Utah. ⋯ Medical costs among compensated Utah patients receiving lumbar fusion have risen dramatically since the 1990s, whereas compensation costs have not. Biopsychosocial variables continue to be predictive of these costs, although to a more modest degree than in prior studies. Further investigations should look at other factors leading to increased medical costs.
