This procedure is used to relieve spinal cord compression in the cervical spine. Its most common use is in severe cases in which the spinal cord is compressed at multiple levels.
This procedure is very similar to a laminectomy. However, instead of completely removing the lamina (bony roof), the lamina is hinged on one side and rotated away from the spinal cord - a procedure similar to cracking open a door.
This procedure allows marked expansion of the spinal canal and relieves compression of the spinal cord. It also is a good alternative to an anterior cervical decompression and fusion. The laminoplasty is performed posteriorly and does not involve fusion of the spine. It allows for decompression of the spinal canal while maintaining good stability.
