Whenever any work is done in the cervical spine, fusions are usually necessary to keep the spine stable. However, if the problem is small enough, a laminotomy or foraminotomy can be performed.
Laminotomy
A laminotomy removes a portion of the lamina, which relieves pressure on the spinal cord and reduces pain.
Foraminotomy
In a foraminotomy, the openings on the sides of the spine (the foramen) are made wider so the nerves are no longer pinched.
