Is it Really Necessary Going All Over the Top in Patients With Symptomatic Lumbar Spinal Stenosis?

The goal of this clinical trial is to evaluate the theory of epidural pressure by comparing a surgical procedure that aims to perform less bone resection compared to conventional surgery in patients with lumbar spinal stenosis. The main questions it aims to answer is: Is bony decompression of the lumbar canal performed until normalization of epidural pressure not inferior to conventional surgery in achieving clinical improvement in patients with symptomatic lumbar canal stenosis? Researchers will: Compare conventional open laminectomy to bony decompression of the lumbar canal until normalization of epidural pressure is achieved. Participants will: * Be randomized to one of the two surgical interventions: laminectomy guided by epidural pressure measure or conventional laminectomy. * Visit the clinic for checkups and tests until 1 year of follow-up.
