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.
Claims74
An implant comprising:
- an implant member adapted to be received in an implant receiving area between a first bone and a second bone comprising at least one aperture adapted to receive a screw having a screw head;
- said implant member comprising at least one arm having a detent that becomes associated with said screw head after said screw is received in said at least one aperture, said detent being adapted to retain said screw in said at least one aperture;
- and
- said at least one arm being flexible, resilient or elastic and having a generally elongated portion having an arm axis that is substantially not parallel relative to a coronal plane of an implantee.
1 more element
An implant comprising:
- an implant member comprising a plurality of apertures each adapted to receive a screw having a screw head;
- and
- a second implant member adapted to be received between bones and having an open end configuration to mate with said implant member.
- said implant member comprising a plurality of arms associated with said plurality of apertures, respectively, in said implant member, said plurality of arms being adapted to retain a plurality of screws in said plurality of apertures, respectively, after said plurality of screws have been received in said plurality of apertures;
- each of said plurality of arms further comprising a generally elongated arm having an elongated arm axis that is generally not parallel to a coronal plane of an implantee;
- said plurality of arms being flexible, resilient or elastic and having a generally elongated portion having an arm axis that is generally not parallel relative to said coronal plane after the implant is implanted.
3 more elements
An implant comprising:
- an implant body having at least one aperture adapted to receive a screw having a locking wall;
- at least one resilient, elastic or flexible arm adapted to capture at least a portion of said locking wall, thereby locking or retaining said screw in said implant.
