Degenerative lumbar stenosis: the neurosurgical perspective.

Degenerative lumbar stenosis is a complex entity caused by predictable patterns of degenerative pathoanatomy. Patients with spinal stenosis are treated by orthopaedic surgeons and neurosurgeons, who often have slightly different ideas regarding treatment strategies. However, data exist to support several recommendations, regarding fusion with or without instrumentation, surgical versus conservative treatment, and limitation of procedures to symptomatic levels. In the current study, the typical patterns of degenerative disease and surgical treatment and a view of the neurosurgical perspective of the treatment of patients with lumbar stenosis are presented.
