Two incisions are made on both sides of the lamina to relieve neural pressure. This creates a hinge on one side and a small hole on the other side of the lamina. A spacer made out of bone, metal or plastic is inserted in order to hold the spinal canal open.

No new-onset spinal deformities, no CSF leaks and a lower rate of spinal deformity progression were observed after laminoplasty for intradural spinal tumor, intra- or extra-medullary tumor resection 1).
