<p>The invention concerns a spinal implant (10) which can be used in a minimally surgically invasive procedure to stabilise upper and lower vertebrae (54, 56) relative to one another. The implant has a rigid body (12) with upper and lower receiving formations (22, 24) to receive spinous processes (58, 60) of the adjacent vertebrae. Arms (14, 16) extend laterally from the body. These can pivot about a posterior-anterior axis (46) relative to the body and are formed with openings (36, 44) spaced laterally from the posterior-anterior axis. The arms can be locked relative to the body when pivoted to positions in which the openings are aligned with the facet joints (76) of the vertebrae so that facet screws (59) can be passed through the openings and engaged in the facet joints thereby to anchor the arms relative to the vertebra and fixate the facet joints.</p> |
