An orthopedic implant is positioned within the facet joint and is attached to the posterior surface of the SAP (superior articular process) of the inferior vertebral bone or onto the anterior surface of the IAP (inferior articular process) of the superior vertebral bone. The implant increases the distance between the IAP and SAP surfaces that make up a facet joint and reduce the joint laxity and at least partially correct the spondylolisthesis produced by a degenerative process.
