The surgeon creates an incision to access the spine.  The surgeon then removes the spinous process from the vertebra that need treatment.  Next they remove the lamina.  Removing the lamina opens up the spinal canal.  This creates more space for the nerves, relieving pressure and decompressing the nerve. The surgeon may also need to treat the foramina.  These are openings on each side of the vertebrae where the nerve roots exit the spine.  When the procedure is complete, the incision is closed with sutures or surgical staples.
