ABSTRACT
Lumbar spinal stenosis refers to a diversity of conditions that decrease the total
area of the spinal canal, lateral recesses, or neural foramina. Lumbar stenosis is
a common disorder that may be present in isolation, with or without associated disk
bulge or herniation, or can be associated with degenerative spondylolisthesis or scoliosis.
Symptomatic lumbar spinal stenosis is characterized by neurogenic claudication and/or
lumbar or sacral radiculopathy. Sixty percent to 85% of properly selected patients
have a satisfactory symptomatic improvement with surgical treatment.
