Comparative Study
Radiographic assessment of degenerative lumbar spinal stenosis: is MRI superior to CT?
To determine the reliability and dependability of magnetic resonance imaging (MRI) and computerized tomography (CT) in the assessment of lumbar spinal stenosis and correlate the qualitative assessment to both a quantitative assessment and functional outcome measures. Multiple studies have addressed the issue of CT and MRI imaging in lumbar spinal stenosis. None showed superiority of one modality. ⋯ This study directly demonstrates that MRI is a more reliable tool than CT, but neither correlates with functional status. Both experience of the reader and the standardization of a qualitative assessment are influential to the reliability.

Satisfaction with the outcome of treatment is a widely used outcome measure but information about the determinants of patient satisfaction after surgery for central spinal stenosis (CSS) are lacking. The aim of the study was to analyze determinants of patient satisfaction 1 year after surgery for CSS without degenerative spondylolisthesis (DS). ⋯ Numerous factors have predictive value for satisfaction of outcome after surgery for CSS without DS. The results from this study can constitute background data in the shared decision making process when discussing surgery with patients suffering from CSS.

Multicenter Study Comparative Study
A comparison between different outcome measures based on "meaningful important differences" in patients with lumbar spinal stenosis.
Patient-reported outcome measures (PROM) are used to measure treatment efficacy in clinical trials. The impact of the choice of a PROM and the cut-off values for 'meaningful important differences' (MID) on the study results in patients with lumbar spinal stenosis (LSS) is unclear. ⋯ The MID in outcome scores for this population varied from 40 to 70 %, depending on the measure or cut-off score used. Further, the disagreement between domain specific measures indicates that differences between studies may be also related to the choice of an outcome measures. An international consensus on the use and reporting of outcome measures in studies on lumbar spinal stenosis is needed.

Multicenter Study
Degenerative lumbar spinal canal stenosis: intra- and inter-reader agreement for magnetic resonance imaging parameters.
To assess the inter- and intra-reader agreement of commonly used quantitative and qualitative image parameters for the assessment of degenerative lumbar spinal canal stenosis (LSS) by magnetic resonance imaging (MRI). ⋯ The inter- and intra-reader agreement of commonly used quantitative and qualitative image parameters for the assessment of LSS showed quite a variability with previously defined core parameters having good to excellent inter- and intra-reader agreements.
