Retrospective analysis of magnetic resonance imaging (MRI) and clinical findings about chemical radiculitis-associated anular tear in patients with radiculopathy. ⋯ The perianular enhancement adjacent to anular tears on MRI may be relevant in the diagnosis of symptomatic chemical radiculitis.

A cross-sectional study. ⋯ Our study highlights the fact that limited physical activity results in high bone turnover rate in patients with LSS.

Randomized Controlled Trial
Therapeutic effect of intrathecal morphine after posterior lumbar interbody fusion surgery: a prospective, double-blind, randomized study.
Prospective, double-blind, randomized, placebo-controlled study. ⋯ We demonstrated the efficacy of 0.4 mg intrathecal morphine after PLIF-surgery as indicated by a significantly lower cumulative piritramide requirement without any serious increase of opioid associated side effects. Therefore, morphine in a dose of 0.4 mg administered intrathecally seems to be a viable alternative therapeutic option to provide postoperative analgesia with PLIF-surgery.

Comparative Study
Clinimetric testing of three self-report outcome measures for low back pain patients in Brazil: which one is the best?
Translation, cross-cultural adaptation, and clinimetric testing of self-report outcome measures. ⋯ The results from this study demonstrate that the Brazilian-Portuguese versions of the RMDQ, the FRI and the PSFS have similar clinimetric properties to each other and to the original English versions. Of allthe measures tested in this study the PSFS seems the most responsive. These measures will enable international comparisons to be performed, and encourage researchers to include Portuguese speakers in their clinical trials.

A prospective cohort. ⋯ The PSAQ was highly responsive to change in patients who report improvement in back symptoms but unlike the ODI and RMDQ was unable to detect deterioration. Overall, the ODI was more responsive than either the PSAQ or the RMDQ.
