About this trial

Long-term clinical results of two methods of surgical treatment (spinal decompression with or without fusion) in patients with single-level lumbar stenosis will be compared. A clear framework for surgical treatment methods and standardized postoperative rehabilitation treatment will be set to obtain the maximum homogeneity of the patient groups.

This trial should provide the first level of evidence for the need for spinal fusion in patients with single-level lumbar stenosis, subject to the high homogeneous comparison groups. Additional results will allow comparing the economic aspects of different surgical treatments for 2 years after surgery.
