Abstract
Stand-alone interbody fusion devices for engagement between adjacent vertebrae. The stand-alone interbody fusion devices may include a spacer or endplates and one or more inserts, members, or frames coupled to the spacer or endplates. The inserts, members, or frames may be configured and designed to provide the apertures which are designed to retain bone fasteners, such as screws or anchors, and secure the implant to the adjacent vertebrae.
Claims14
An intervertebral implant for implantation in an intervertebral space between adjacent vertebrae, the implant comprising:
- a frame having a front portion and a plurality of arms extending from the front portion and joined together to form a ring-like structure, the front portion at least partially defining a fastener aperture sized and dimensioned for receiving a fastener;
- and
- at least one endplate including at least one outer surface having a contact area configured to engage adjacent vertebrae, the at least one endplate being affixed to the frame such that the at least one endplate contacts at least a portion of the plurality of arms,
- wherein the frame includes a rear portion that extends from an upper surface to a lower surface configured to contact adjacent vertebral bodies, the rear portion configured to be sized to be equal to a width and height of the at least one endplate.
A stand-alone implant for implantation in a treated area of an intervertebral space between vertebral bodies of a spine, the implant comprising:
- a frame including a front portion having a first end and a second end, a first arm extending orthogonally from the first end of the front portion, and a second arm extending orthogonally from the second end of the front portion, wherein the first and second arms join together at a rear portion to form a continuous ring-like body, and at least one hole traversing the front portion for receiving a fastener;
- and
- at least one endplate secured to the frame such that the at least one endplate rests on at least one of the first and second arms, the at least one endplate forming a superior surface, an inferior surface, or both of the superior surface and the inferior surface to form a contact area configured to engage adjacent vertebrae,
- wherein the frame includes a rear portion that extends from an upper surface to a lower surface configured to contact adjacent vertebral bodies, the rear portion configured to be sized to be equal to a width and height of the at least one endplate.
