To compare patient outcomes and complication rates after different decompression techniques or instrumented fusion (IF) in lumbar spinal stenosis (LSS). ⋯ As already demonstrated in the literature, decompression in patients with LSS is a very effective treatment. Despite better patient outcomes after laminectomy in combination with IF, caution is advised due to higher rates of surgical and general complications and consequent required measures. Based on the current study, laminotomy or laminectomy, rather than hemilaminectomy, is recommendable for minimum relevant pain relief.

To determine the static and dynamic radiological findings characteristic of symptomatic foraminal stenosis. ⋯ A large segmental range of motion in sagittal plane of L5-S1 and posterior instability of L5 are risk factors for symptomatic L5-S1 foraminal stenosis. These dynamic radiological findings support the diagnosis of symptomatic foraminal stenosis.
