A process for performing lumbar laminectomy is characterized by leaving the muscles intact along the base of spinous process and posterior faces of detached portions of lamina, facet joints, and transverse processes of at least one of adjacent superior and inferior vertebrae to preserve the blood flow to the detached portions and, thus, to create a living peace of bone used as fusion material between the bases of the transverse processes of the superior and inferior vertebrae.
