Surgical treatment of lumbar spinal stenosis in the elderly.
Unrelenting sciatica or intermittent neurogenic claudication in the elderly may be caused by degenerative lumbar spinal stenosis. This rather common condition is produced by advanced multilevel disc degeneration leading to facet hypertrophy, infolding of ligamentum flavum, descent of the pedicles, and occasional disc herniation. The symptoms of lumbar spinal stenosis usually do not improve with time. Despite the advanced age of some patients, surgical decompression may offer significant relief. Of 19 patients who underwent lumbar decompressive laminectomy, 18 showed sufficient improvement to return to normal daily activities.
