The term lumbar spinal stenosis can refer to one or more of the following anatomic states:

Narrowing of the intraspinal (central) canal

Narrowing of the lateral recess

Narrowing of the neural foramen

This topic will focus on the pathophysiology, clinical features, and diagnosis in regard to stenosis of the intraspinal (central) lumbar canal. This condition, most commonly caused by degenerative bone disease, is increasingly recognized as a cause of disability in the aging population [1,2].
