Abstract
A spinal implant includes a wall defining a plane and having a first surface and a second surface configured to engage tissue. The wall defines a first opening configured for disposal of a first bone fastener and a second opening configured for disposal of a second bone fastener. The wall includes an inner surface that defines a passageway disposed between the first and second openings. A part configured for disposal in the passageway. The first bone fastener is engageable with the part such that the part translates relative to the inner surface in the plane to engage the second bone fastener and to resist backout of the second bone fastener from the second opening. Systems and methods are disclosed.
Claims20
A spinal implant comprising:
- a wall defining a plane and having a first surface and a second surface configured to engage tissue, the wall defining a first opening configured for disposal of a first bone fastener and a second opening configured for disposal of a second bone fastener, the wall including an inner surface that defines a passageway disposed between the first opening and the second opening;
- and
- a part configured for disposal in the passageway, the first bone fastener being engageable with the part such that the part translates relative to the inner surface in the plane to engage the second bone fastener and to resist backout of the second bone fastener from the second opening.
A spinal implant comprising:
- a plate defining a plane and having a first surface and a second surface configured to engage vertebral tissue, the plate defining a first opening configured for disposal of a first bone fastener having a proximal portion that defines an implant cavity and a distal portion configured to penetrate the vertebral tissue,
- the plate defining a second opening configured for disposal of a second bone fastener having a proximal portion that includes a shoulder and a distal portion configured to penetrate the vertebral tissue,
- the plate including an inner surface having flanges that define a channel disposed between the first opening and the second opening;
- and
- a slider,
- wherein the slider is translatable along the channel in the plane between a first orientation such that the second bone fastener is moveable within the second opening and a second orientation such that the first bone fastener engages the slider to translate the slider relative to the inner surface to overlap the shoulder to resist backout of the second bone fastener from the second opening.
A spinal implant comprising:
- a plate defining a plane and having a first surface and a second surface configured to engage vertebral tissue, the plate defining a first opening configured for disposal of a first bone fastener having a proximal portion that defines an implant cavity and a distal portion configured to penetrate the vertebral tissue,
- the plate defining a second opening configured for disposal of a second bone fastener having a proximal portion that includes a shoulder and a distal portion configured to penetrate the vertebral tissue,
- the plate including an inner surface that defines a first mating part disposed between the first opening and the second opening;
- and
- a rotatable part including a slider configured to engage the bone fasteners, an intermediate portion and a second mating part configured for mating engagement with the first mating part,
- wherein the rotatable part is movable in the plane between a first orientation such that the second bone fastener is moveable within the second opening and a second orientation such that the first bone fastener engages the slider to rotate the slider relative to the inner surface to overlap the shoulder to resist backout of the second bone fastener from the second opening.
