Spinal stenosis is a narrowing of spaces in the spine (backbone) that results in pressure on the spinal cord and/or nerve roots. Some of its surgical treatments include: –
A cervical laminoplasty is often performed to relieve the symptoms of spinal stenosis. It is a surgical procedure that treats a painfully restricted spinal canal by creating more space for the spinal cord and nerve roots, immediately relieving pressure.
Cervical Corpectomy is also used as surgical treatment of spinal stenosis when a portion of the vertebra and adjacent intervertebral discs are removed for decompression of the cervical spinal cord and spinal nerves.
Foraminotomy (when the foramen, the area where the nerve roots exit the spinal canal, is removed to increase space over a nerve canal) is also used as surgical treatment of spinal stenosis. This surgery can be done alone or along with a laminoplasty.
