Surgical treatment of lumbar canal stenosis in the elderly

The effectiveness of spinal surgery for lumbar canal stenosis was investigated in the elderly. 164 patients with lumbar canal stenosis were surgically treated over 8 years. 125 patients were followed up by letter questionnaire. The outcome and patient satisfaction with the surgical procedures were compared between the 73 younger patients (< or = 64 years of age) and the 52 elderly patients (> or = 65 years of age). Intermittent claudication was satisfactorily improved in both the younger and the elderly groups. Both simple laminectomy and laminectomy with fusion could equally improve the symptoms of intermittent claudication. Although statistically not significant, there was tendency that laminectomy plus fusion effectively improved the symptoms of back pain and leg pain in both groups. 75% of the younger patients and 67% of the elderly were pleased with the outcome. The present study shows that elderly patients with lumbar canal stenosis should be actively considered for surgical treatment.
