NCT03365401

Brief Summary

Decompression surgery has proved to be effective for Lumbar Spinal Stenosis (LSS) with persistent pain. But the efficiency of the surgery for degenerated LSS remain uncertain and is the subject of this study. This is a multiple center open-label randomised trial. Patients were randomly allocated to surgical group or a nonoperative group. Because of the procedure , neither patients nor investigators were blinded. The primary outcome is the change of symptom measure by the Oswestry disability index 6, 12, and 24 months after procedure.

Eligibility Criteria

Age50 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
