title: [Lumbar spinal stenosis--claudicatio spinalis. Pathophysiology, clinical aspects and treatment].
abstract: The lumbar spinal stenosis (LSS) is defined as a narrowing of the spinal canal together with neuronal and vascular structures via circumjacent bone and soft tissue. In patients aged over 65 years, the LSS is among the most frequent causes of lumbago, either with or without sciatica. The prevalence will continue to augment because of the increased life expectancy. The leading symptom is neurogenic claudicatio with lumbogluteal or sciatic pain, which occurs while walking and leads to a limitation of the walking distance. Its typical constellation of symptoms including subjective leg weakness is leading to the tentative diagnosis. Nowadays, the imaging technique of choice for the diagnosis is magnetic resonance imaging. A conservative treatment is initially sufficient in most cases. The indication for surgery is given, if the pain and limitation of walking distance are not tolerable any more. Additional fusion should be taken into account, when degenerative spondylolisthesis or other pathomorphological alterations result in an instability. Conservative and surgical therapeutic goals imply pain relief, amelioration of the physical functionality, mobility and general quality of life.
