[Surgical treatment of lumbar spinal canal stenosis in elderly patients]

Lumbar spinal stenosis is one of the most frequent causes of spinal surgical interventions in over 60-year olds. The exact relationship between degenerative changes and the resulting symptoms is unclear since imaging shows stenotic changes in the spines of many symptom-free patients. The concurrence of imaging findings, the symptoms described and manifestations is crucial for the indication of surgical decompression. Nevertheless, spinal claudication that is refractory to conservative therapy is the most frequent indication for surgery. The success rate two years after OP is approximately 80% in over 75-year olds. Five years after surgical intervention, an improvement in the symptoms is still recognizable in 50% of these patients.
