Stenosis occurs as people age and the ligaments
of the spine thicken and harden, discs bulge, bones and joints
enlarge, and bone spurs (called osteophytes) form. Spondylolisthesis
(the slipping of one vertebra onto another) can also lead
to compression.
The goal of a laminectomy is to relieve pressure on the spinal
cord or spinal nerve by widening the spinal canal. This is
done by removing or trimming the lamina (roof) of the vertebrae
to create more space for the nerves.
