An interbody at least one surface including a plurality of members that are independently configured and dimensioned to move from a first position to a second position is disclosed.

An implant may include a body having a first blade having a first retracted position in the body and a first extended position where the first blade extends outwardly from the body, a second extendable blade, and a blade actuating member configured to translate through the body in directions parallel to the lateral axis. When the blade actuating member is moved in a first direction along the lateral axis, the first blade moves towards the first extended position; and in the first extended position, the first blade extends from the superior surface at a first non-zero angle with respect to the superior-inferior axis; and the second blade moves towards a second extended position in which the second blade extends from the inferior surface at a second non-zero angle with respect to the superior-inferior axis.

An intervertebral scaffolding system is provided having a laterovertically-expanding frame operable for a reversible collapse from an expanded state into a collapsed state, the laterovertically-expanding frame having a stabilizer, one or more tensioners, or a combination of the stabilizer with one or more tensioners. The stabilizer slidably engages with the distal region of the laterovertically-expanding frame and both the stabilizer and the one or more tensioners are configured for retaining the laterovertically-expanding frame from a lateral movement that exceeds the expanded state, and the stabilizer can include a locking element that engages with the expansion member to lock the expansion member to the stabilizer when the expansion member is fully inserted into the frame. The expanded state, for example, can be configured to have an open graft distribution window that at least substantially closes upon the reversible collapse.

A spacer for separating bones of a joint, the spacer includes a first endplate configured to engage a first bone of the joint; a second endplate configured to engage a second bone of the joint; tissue engaging projections, wherein the tissue engaging projections are moveable from a retracted position to a deployed position; and an actuation subassembly that extends between the first endplate and the second endplate, wherein the actuation subassembly comprise a drive nut, a drive screw coupled to the drive nut, and a cam frame coupled to the drive screw, wherein the cam frame is disposed between the first endplate and the second endplate to engage the tissue engaging projections.

An expandable implant may include a superior endplate and an inferior endplate. The superior endplate may have at least one track extending in a proximal-to-distal direction and an inferior endplate may have at least one track extending in the proximal-to-distal direction. An adjusting shim may be disposed within the at least one track to adjust a spacing and angle of inclination of the implant. Some embodiments may include a plurality of tracks for adjusting a spacing and an angle of inclination between the superior endplate and the inferior endplate. Some embodiments may be configured to adjust an orientation of the implant relative to a disc space in both the sagittal plane and the coronal plane. Various embodiments disclosed herein may be used in an Anterior lumbar interbody fusion (ALIF), Transforaminal lumbar interbody fusion (TLIF), or a lateral Lumbar Interbody Fusion (LLIF) procedure, for example.

A method of joining adjacent bone includes providing a medical device having a first implant portion, a second implant portion attached to the first implant portion, and a driver assembly having an instrument adapted to form an opening in bone. The driver assembly is integrally connected to and removably attached to the second implant portion at a connection, distal from the first implant portion. The driver assembly further has a wire driver extending therefrom, distal from the first implant portion. The method further includes inserting the wire driver into a wire driver tool; placing the first implant portion against a first bone structure; inserting the first implant portion into the first bone structure; removing the second implant portion from the driver assembly; using the driver assembly to form an opening in a second bone structure, adjacent to the first bone structure; and inserting the second implant portion into the opening.

The present invention relates to an intervertebral fusion device (10) comprising a superior component (12), an inferior component (14) and a core component (16). The superior component (12) and the inferior component (14) are receivable in an intervertebral space between first and second vertebrae with the core component (16) insertable between the superior and inferior components to determine a separation between the superior and inferior components. A bone graft conveying aperture is defined in at least one of a superior component top surface (18) of the superior component and an inferior component bottom surface (20) of the inferior component. The core component defines a bone graft material holding space which is enclosed except at at least one of a core component top surface and core component bottom surface of the core component and a bone graft material delivery opening. The bone graft material delivery opening extends from outside the core component side to the bone graft material holding space. The bone graft material delivery opening is closed by a closure component.

The present invention relates to an intervertebral fusion device (10) comprising a superior component (20), an inferior component (40), and a core component (80) inserted there between. The intervertebral fusion device further comprises first and second retention mechanisms which resist ejection of the core component from between the superior and inferior components. Each of the first and second retention mechanisms comprises first and second portions. One of the first and second portions is unitary with one of the superior and inferior components. The other of the first and second portions is unitary with the core component. The first and second portions each comprise an inter-engaging formation which are urged in an opposite direction. The first inter-engaging formation is urged to inter-engage with the second inter-engaging formation upon insertion of the core component between the superior and inferior components.

The present invention relates to an intervertebral fusion device (10) comprising a superior component (20), an inferior component (40) receivable in an intervertebral space between first and second vertebrae, with the core component (80) insertable between the superior and inferior components to determine a separation between the superior and inferior components. The superior, inferior components and core components comprise respective formations and profiles. The formations (54, 68) present a barrier to separation of the core from one of the inferior and superior components during insertion of the core component. The profiles guide the core component during insertion of the core component while presenting no barrier to separation from each other during its insertion. The components comprise further formations (39, 76) which present a barrier to separation of the components from each other once the core has been fully inserted between the inferior and superior components.

A bone structural device including a plurality of bone structural segments, wherein adjacent bone structural segments are pivotally connected to one another about a pivot axis, and the bone structural segments are expandable in height, which is in a direction generally parallel to the pivot axis.
