Abstract
Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer and one or more inserts or members coupled to the spacer. The inserts or members may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws, and secure the implant to the adjacent vertebrae.
Claims20
An implant for implantation in an intervertebral space between adjacent vertebrae, the implant comprising:
- a spacer having a superior surface, an inferior surface, a proximal end, and a distal end configured for insertion into the intervertebral space, wherein the superior surface and the inferior surface each have a contact area configured to engage adjacent vertebrae, the spacer defining a central opening extending from the superior surface to the inferior surface of the spacer, and the distal end of the spacer having a first spring feature configured to allow for compression and expansion of the spacer;
- and
- an anterior portion extending from the proximal end of the spacer such that the anterior portion and the spacer are a single piece, the anterior portion having an upper surface, a lower surface, a first lateral portion, a second lateral portion, and at least one hole traversing the anterior portion for receiving a fastener, wherein at least a portion of the upper surface or the lower surface of the anterior portion extends beyond the superior surface or the inferior surface of the spacer,
- wherein the superior surface and the inferior surface of the spacer are configured with a roughened or porous surface.
