Abstract
An implant assembly is shown and described. The implant has at least one or a plurality of elastic, resilient or flexible arms that each have a detent adapted to retain at least one screw in a locked position in the implant. At least one of the arms has a portion that extends into a screw aperture such that an arm axis is generally parallel to the axis of the screw after the screw is received in the implant. In another embodiment, means or a system for locking the multi-component implant members together is shown.
Claims62
An implant comprising:
- an implant member adapted to be received in an implant receiving area between a first bone and a second bone, said implant member comprising a first wall containing at least one or a plurality of apertures wherein each of the at least one or a plurality of apertures are adapted to receive one screw having a screw body comprising a screw head and a threaded portion, wherein a top surface of the screw head extends transverse to a longitudinal axis of said threaded portion of the screw, said implant member having a first bone-engaging surface and a second bone-engaging surface opposite to the first bone-engaging surface having an imaginary plane lying midway between said first bone-engaging surface and said second bone-engaging surface;
- said first wall of said implant member comprising at least one or the plurality of arms extending from said first wall, and wherein each of said at least one or a plurality of arms comprises a detent comprising an inner surface, wherein the inner surface associated with said top surface of said one screw head after said one screw is received in each aperture of said at least one or the plurality of apertures, said detent being adapted to retain said one screw in each aperture of said at least one or the plurality of apertures, wherein each arm of said at least one or the plurality of arms comprises a generally elongated portion, the generally elongated portion defining an arm axis,
- each arm of said at least one or the plurality of arms being flexible, resilient or elastic, and wherein
- each aperture of said at least one or the plurality of apertures comprises an aperture axis parallel to a longitudinal axis of said one screw received in the each aperture said at least one or the plurality apertures, said arm axis of each arm of said at least one or the plurality of arms being generally parallel to said longitudinal axis of a screw received in the aperture.

An implant comprising:
- a first implant member comprising at least one or a plurality of apertures each aperture of said at least one or the plurality of apertures adapted to receive a screw having a screw body comprising a screw head, and a threaded portion, wherein a top surface of the screw head extends transverse to a longitudinal axis of said threaded portion of the screw, said first implant member having a first bone-engaging surface and a second bone-engaging surface opposite the first bone-engaging surface, and an imaginary plane lying midway between said first bone-engaging surface and said second bone-engaging surface;
- a second implant member adapted to be received between bones, said second implant member having an opening to receive and mate with said first implant member;
- said first implant member comprising at least one or a plurality of arms, each arm extending between said first and second bone-engaging surfaces, each arm of said at least one said plurality of arms associated with each aperture of said at least one of said plurality of apertures, in said first implant member, said each arm of said at least one or said plurality of arms being adapted to retain a screw in said each aperture of said at least one or said plurality of apertures, respectively, after said screw have been received in said each aperture of said at least one or said plurality of apertures, wherein at least a portion of said each arm of said at least one or said plurality of arms engages with said top surface of said screw;
- said each aperture of said at least one or said plurality of apertures having an aperture axis for receiving said screw, said arm axis of said at least one or said plurality of arms being generally parallel to said aperture axis;
- and
- said each arm of said at least one or said plurality of arms being flexible, resilient or elastic and each arm having a generally elongated portion having an arm axis, wherein the arm axis is coplanar to said aperture axis;
- wherein said first implant member comprises a plurality of walls, each wall of said plurality of walls define said at least one or said plurality of apertures, respectively, said each aperture of said at least one or said plurality of apertures having an aperture axis and at least one arm of said at least one or said plurality of arms associated therewith, said arm axis of said generally elongated portion being generally parallel to said aperture axis.

An implant comprising:
- an implant body adapted to be received in an implant receiving area between a first bone and a second bone, said implant body comprising at least one or a plurality of apertures, each aperture adapted to receive one screw having a screw body comprising a screw head and a threaded portion, wherein a top surface of the screw head extends transverse to a longitudinal axis of said threaded portion of the screw, the screw head defining a locking wall, said implant body having a first bone-engaging surface and a second bone-engaging surface opposite the first bone-engaging surface having an imaginary plane lying midway between said first and said second bone-engaging surfaces;
- said implant body comprising at least one or a plurality of resilient, elastic or flexible arms, each arm having a detent comprising an inner surface, wherein the inner surface is associated with said top surface of said screw head after said one screw is received in each of said at least one or said plurality of apertures, said detent being adapted to capture at least a portion of said locking wall of said screw, thereby locking or retaining said screw in said implant;
- each of said at least one or said plurality of resilient, elastic or flexible arms having a generally elongated portion having an arm axis;
- and
- said at least one or said plurality of apertures having an aperture axis for receiving said screw, said arm axis of said generally elongated portion being generally coplanar to said aperture axis.
