Cross-sectional retrospective review of 539 patients with lumbar spine magnetic resonance imaging (MRI). ⋯ Lumbar interspinous bursitis (Baastrup disease) is uncommon but not infrequent in symptomatic patients undergoing lumbar spine MRI. Patients with MRI evident Baastrup disease tend to be older, have central canal stenosis, bulging discs, and anterolisthesis. Further investigations determining the clinical significance of this finding are necessary.

Prospective validity study. ⋯ Based on these findings, we recommend use of live fluoroscopy to observe dynamic contrast flow during transforaminal epidural steroid injections.
-
An observational prospective cohort study. ⋯ For trained observers of a population of patients with CLBP in a rehabilitation setting, the interobserver reliability of the Waddell score was moderate and the intraobserver reliability was good. No influence of clinical characteristics was found on interobserver reliability. To optimize the homogeneity and variability of the Waddell score, we recommend summing up the individual signs instead of summing up the categories.

A retrospective evaluation of diffusion-weighted imaging, apparent diffusion coefficient (ADC) maps, and T2-weighted images in patients with cervical compression myelopathy. ⋯ ADC maps demonstrated internal changes in the early stages of chronic spinal cord compression, but had limitations for the detection of intramedullary changes in late-stage myelopathy.

Do corticosteroids produce additional benefit in nerve root infiltration for lumbar disc herniation?
Experimental animal study. ⋯ NRI prevented mechanical allodynia. However, no additional benefit from using corticosteroid was identified, suggesting that corticosteroid may be unnecessary for NRI.
