Lumbar spinal stenosis: conservative or surgical management?: A prospective 10-year study.
STUDY DESIGN A cohort of 100 patients with symptomatic lumbar spinal stenosis , characterized in a previous article , were given surgical or conservative treatment and followed for 10 years . OBJECTIVES To identify the short- and long-term results after surgical and conservative treatment , and to determine whether clinical or radiologic predictors for the treatment result can be defined . SUMMARY OF BACKGROUND DATA Surgical decompression has been considered the rational treatment . However , clinical experience indicates that many patients do well with conservative treatment . METHODS In this study , 19 patients with severe symptoms were selected for surgical treatment and 50 patients with moderate symptoms for conservative treatment , whereas 31 patients were r and omized between the conservative ( n = 18 ) and surgical ( n = 13 ) treatment groups .  Pain was decisive for the choice of treatment group . All patients were observed for 10 years by clinical evaluation and question naires . The results , evaluated by patient and physician , were rated as excellent , fair , unchanged , or worse . RESULTS After a period of 3 months , relief of pain had occurred in most patients . Some had relief earlier , whereas for others it took 1 year . After a period of 4 years , excellent or fair results were found in half of the patients selected for conservative treatment , and in four fifths of the patients selected for surgery . Patients with an unsatisfactory result from conservative treatment were offered delayed  surgery  after 3 to 27 months ( median , 3.5 months ) . The treatment result of  delayed surgery  was essentially similar to that of the initial group . The treatment result for the patients r and omized for surgical treatment was considerably better than for the patients r and omized for conservative treatment . Clinical ly significant deterioration of symptoms during the final 6 years of the follow-up period was not observed . Patients with multilevel afflictions , surgically treated or not , did not have a poorer outcome than those with single-level afflictions . Clinical or radiologic predictors for the final outcome were not found . There were no dropouts , except for 14 deaths . CONCLUSIONS The outcome was most favorable for surgical treatment . However , an initial conservative approach seems advisable for many patients because those with an unsatisfactory result can be treated surgically later with a good outcome
