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 intervertebral 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, wherein the superior surface and the inferior surface each have a contact area configured to engage adjacent vertebrae, the spacer defining an opening extending from the superior surface to the inferior surface of the spacer, and the spacer defining a cutout extending from the proximal end to the opening;
- and
- a plurality of inserts, each insert at least partially defining a fastener aperture sized and dimensioned for receiving a fastener, wherein each insert is coupled to the spacer such that at least a portion of the insert is received in the cutout in the spacer
- wherein the superior surface and the inferior surface are configured with a roughened or porous surface, and
- wherein the plurality of inserts are spaced from each other.
A stand-alone implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine, the implant comprising:
- a spacer having a first spacer portion and a second spacer portion, each of the first and second spacer portions having a first end and a second end, wherein the second end of the first spacer portion is coupled to the first end of the second spacer portion, the first and second spacer portions forming a superior surface and an inferior surface, wherein the superior surface and the inferior surface each have a contact area configured to engage adjacent vertebrae;
- and
- a plurality of members, each member having an upper surface, a lower surface, a first lateral portion, a second lateral portion, and at least one hole traversing the member for receiving a fastener;
- wherein each member is coupled to the spacer such that the first end of the first spacer portion engages the first lateral portion of the member and the second end of the second spacer portion engages the second lateral portion of the member
- wherein the superior surface and the inferior surface of the spacer and the upper and lower surface of the member are configured with a roughened or porous surface, and
- wherein each member is paced from the other member.
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 an 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 and the upper and lower surface of the member are configured with a roughened or porous surface.
