A spine stabilization and fusion system includes a lateral cage having a lateral cage bore hole. The system also includes a lateral cage insertion shaft comprising a leading end, a mid-portion, and a terminal end. A shape of the leading end matches a shape of the lateral cage bore hole such that the leading end mates with the lateral cage bore hole via a friction fit. The system also includes a lateral plate having a lateral plate bore hole and a plurality of holes, where the lateral plate bore hole receives the mid-portion of the lateral cage insertion shaft, and where the plurality of holes receive fasteners to couple the lateral plate to one or more vertebra.

Systems for improved methods of performing a spinal fusion procedure that include an implant having an alignment guide system. The alignment guide system may include one or more guide lines configured to provide a visual indication when the implant is properly aligned within the disc space. In some embodiments, the system includes one or more tamp levelers that also aid with the proper alignment of the implant within the disc space.

An expandable intervertebral implant including a first wall comprised of a male portion and a female portion in telescoping engagement with each other and a second wall comprised of a plurality of links, wherein the first wall and second wall are coupled to each other by hinges at each of the leading and trailing ends of the implant. The expandable implant is configured to be inserted into a disc space in a collapsed, narrow profile configuration and then unilaterally expanded in an anterior or posterior direction to a fully expanded, larger foot print configuration.

A bone implant for enclosing bone material is provided. The bone implant comprises a mesh having an inner surface and an outer surface opposing the inner surface. The inner surface is configured to receive a bone material when the inner surface of the mesh is in an open configuration. A plurality of projections are disposed on or in at least a portion of the inner surface of the mesh. The plurality of projections extend from at least the portion of the inner surface of the mesh and are configured to engage a section of the inner surface of the mesh or a section of the outer surface of the mesh or both sections of the inner and outer surfaces of the mesh in a closed configuration so as to enclose the bone material. A tray, a kit and a method of making the bone implant are also provided.

An expandable medical implant that includes a lower lifting plate, an upper lifting plat, a distal lifting block, a proximal lifting block, a rotational block, a lifting screw, and a locking nut, and related methods of use. Also, an expandable medical implant that includes a lower lifting plate having a proximal lower angled lifting portion, an upper lifting plate having a proximal upper angled lifting portion, a center fork block, a lifting lobe, a distal screw, and a proximal nut, and related methods of use.

A method of inserting an expandable intervertebral implant is disclosed. The implant preferably includes first and second members capable of being expanded upon movement of first and second wedges. The first and second wedges, while being capable of moving with respect to each other and the first and second members are also preferably attached to the first and second members. In addition, the first and second wedges are preferably capable of moving only in a first direction, while movement in a second direction is inhibited. The first and second wedges are also preferably prevented from torsionally moving with respect to the first and second members.

A knee joint endoprosthesis apparatus includes a tibial component for anchoring to a tibia and a meniscal component. The tibial component and the meniscal component are coupled to one another in a coupling position and are completely separated from one another in a separating position. The tibial component has a top side defining an abutment plane, against which a bottom side of the meniscal component abuts in the coupling position. The knee joint endoprosthesis apparatus also includes a coupling device for coupling the tibial component and the meniscal component in the coupling position. The knee joint endoprosthesis apparatus is transferrable from the separating position into the coupling position by a relative movement of the tibial component and the meniscal component.

A joint spacer has first and second endplates, with each having a bone engaging surface, and at least two cams with an inclined cam surface positioned on an opposite side. First and second slides, each having ramps with an inclined surface are engaged with the cams of the endplate. The first slide has an angled portion at an end, and the second slide has a hinge portion. A threaded shaft has a hinge portion connected to the slide hinge portion, connecting the shaft to the slide, enabling the shaft to pivot. A nut is threaded to the shaft, and can contact and interfere with the angled portion of the first slide to drive the first slide with respect to the second slide. This results in engagement of the cams and ramps to drive the endplates apart to increase the spacer height.

An expandable cage system for use in spinal surgery includes a top portion having an outwardly extending top arm, and a bottom portion having an outwardly extending bottom arm. The bottom arm is configured to engage with the top arm such that upon engagement, the top portion and the bottom portion are substantially restricted from movement relative to each other in an anterior-posterior direction, and in a medial-lateral direction. The expandable cage system further includes a removable shim configured to be positioned between the top portion and the bottom portion to hold the expandable cage in an expanded position within a spinal cavity.

Techniques and systems for distracting a spinal disc space and supporting adjacent vertebrae are provided. Trial instruments are insertable into the disc space to determine a desired disc space height and to select a corresponding implant. Implants can be also be self-distracting and the implant providing the desired disc space height can be implanted in the spinal disc space.
