RESUMEN
BACKGROUND AND OBJECTIVE: Non-operative treatment is widely accepted for early stages of lumbar spinal stenosis. In general, a trial of conservative treatment is recommended prior to surgery. However, there is an ongoing debate regarding benefits from non-operative treatment and their duration. METHODS: Thirty-eight patients were included in this prospective study. All patients received repeated epidural injections and facet joint injections as well as physiotherapy during a one week hospitalization. Patient characteristics, VAS scores, COMI and ODI scores and SF-36 were assessed prior to and immediately after treatment as well as after six, twelve, and 26 weeks. For six weeks after treatment, patients were asked to record a pain diary. RESULTS: Back and leg pain scores improved significantly on VAS up to three months follow-up. COMI score improved significantly over the entire follow-up. Regarding quality of life, mental sub-scores showed no improvement. Physical component summary scores improved for the first three months. CONCLUSIONS: Non-operative treatment offers pain relief and improves physical function for three months. COMI scores improve up to six months follow-up. Spine Tango registry offers standardized instruments for outcome evaluation of non-operative treatment.
