An implant comprising a plurality wedge components configured to be inserted into a disc space, the implant comprising:
- a first component having a first ramped surface;
- and
- a second component having a complementary ramp surface,
- wherein advancement of the second component and complementary ramp surface against the first component and first ramped surface in a first direction causes the first component to move in a second direction that is generally perpendicular to the first direction.
A wedge system configured for insertion of at least one wedge component into a disc space, comprising:
- a first wedge component comprising a first wedge component first ramped surface;
- a wedge system cannula with a longitudinal axis;
- and
- a ramped insertion tool slideably movable along the longitudinal axis of the wedge system cannula,
- wherein a first direction is parallel to the longitudinal axis of the wedge system cannula;
- wherein a second direction is generally perpendicular to the first direction, and
- wherein advancement of the ramped insertion tool against the first component in the first direction causes the first component to move in the second direction.
A method of inserting a plurality of wedge components through a trans-sacral access point into a disc space, the method comprising:
- accessing the disc space through the trans-sacral access point;
- inserting a first component via a trans-sacral approach into the disc space;
- inserting a second component through the sacrum into the disc space towards the first component;
- pushing the first component radially towards a disc annulus with the second component.
