Spinal Stenosis

Spinal stenosis is defined as any developmental or acquired narrowing of the spinal canal, nerve root canals (lateral recess), or intervertebral foramina that result in compression of neural (nerve) elements. Most patients with spinal stenosis experience low back pain, with or without radiation into the leg, with standing or walking. These symptoms are often relieved with rest, lying down, sitting, or bending forward at the waist.
