Ulrich NH, et al. - The authors aimed to ascertain whether patients with confirmed multisegmental lumbar spinal stenosis benefit more from a single-level or a multilevel decompression. A single-level decompression was associated with a significantly more favorable Spinal Stenosis Measure (SSM) symptoms and function score in multisegmental stenotic cases. The evidence thus suggested that in these cases a single-level decompression could be sufficient to improve patient’s symptoms and function.
