Self-broaching, rotatable, push-in interbody fusion implant and method for deployment thereof

摘要: An interbody spinal fusion implant (20) for insertion across a disc space between adjacent vertebral bodies of human spine has body (22) two top side and bottom junctions, with at least pair diagonally opposed junctions having distance therebetween that does not significantly exceed the height. The also includes one or more bone penetrating protrusions (36) extending outwardly from upper lower walls implant. is inserted on its (28, 28') then rotated 90 degrees into place. protrusionsm penetrate endplates upon rotation, thereby securing within spine. passage (38, 38') therethrough wall (30) to (30') promote through (20). Because specialized overdistraction avoided when an initial position final deployed position.
