Ulrich NH, et al. - The experts embraced this study to evaluate whether patients with confirmed multisegmental lumbar spinal stenosis benefited more from a single-level or a multilevel decompression. When compared with multilevel decompression, in multisegmental stenotic cases a single-level decompression was correlated with a significantly more favorable Spinal Stenosis Measure (SSM) symptoms and function score, respectively. This study presented evidence that in multisegmental stenotic cases a single-level decompression could be sufficient to improve patient’s symptoms and function.
