The aim of this study was to compare the clinical outcome of spinal process osteotomy with two other midline-retaining methods, bilateral laminotomy and unilateral laminotomy with crossover, among patients undergoing surgery for lumbar spinal stenosis. ⋯ In a propensity scored matched cohort, there were no differences in the clinical outcome 12 months after surgery for lumbar spinal stenosis performed using the three different posterior decompression techniques. Bilateral laminotomy had shortest duration of surgery and shortest length of hospital stay. Surgical technique does not seem to affect clinical outcome after three different midline-retaining posterior decompression techniques.

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.

Multiple outcome measures exist to evaluate the outcomes of spinal decompression surgery; however, these tend to be complex and are difficult to express to the patient pre-operatively to accurately guide their expectations. We present outcomes, in terms of walking distance measurement, of a prospective single surgeon series of 76 consecutive patients with spinal stenosis. ⋯ This study demonstrates that walking distance is an accurate and accessible method of determining surgical outcomes.

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.
