Introduction: degenerative lumbar spinal stenosis is a serious health problem in the older adults at present. The surgical treatment seems to attain better results, but the controversy is whether all the patients suffering the disease can be treated with this procedure or not. Objectives: to show the results of the surgical treatment of degenerative lumbar spinal stenosis in over 65 years-old patients. Methods: a prospective and descriptive study was carried out in patients aged over 65 years and diagnosed with degenerative lumbar spinal stenosis in the Center of Research on Old Age, Aging and Health from January 1^st 2009 to January 1^st, 2011. The series was finally made up of 28 patients. The study variables were age, sex, symptoms, location, main comorbid conditions, and classification according to radiographies and to magnetic resonance. The choice of the surgical technique depended on the stenosed anatomical area. The Oswestry Disability Index and the Analogue Visual Scale of pain were the evaluation instruments. Results: males (67.6 %), the location of disease at two vertebral levels and comorbid cardiovascular conditions prevailed. The predominant symptom showed similar values among lumbar pain, the irradiated pain and claudication. Oswestry Disability Index and the Analog Visual Scale of pain showed the significant improvement of patient in the postsurgical period. Good results reached 89.2 %. Conclusions: laminectomy for central stenosis and regaging for the lateral recess seem to be adequate.
