Foraminal stenosis

A foraminal stenosis is relieved by enlarging the foramen (opening) with tiny reamers to make more room for the nerve root. Any hernia that may be present is also removed from the foramen.

A foraminal stenosis is a narrowing of the opening through which a nerve branches out from the spinal cord. The bone squeezes the nerve, causing the symptoms to appear. Dr. Iprenburg applies the PTED procedure to slightly enlarge the opening. This relieves the pressure on the pinched nerve.
