The implant is configured to engage the vertebrae in a predetermined alignment and the gear member includes gear teeth exposed to the exterior and configured to be accessible by a tool member at a plurality of angular positions around the perimeter of the implant device.

Abstract: Provided herein are bone grafts and methods of making and using the same, as well as products and kits that include such bone grafts. In particular, bone grafts are provided that include osteogenic stem cells in a mix of osteoinductive demineralized bone matrix and osteoconductive cortico-cancellous chips.

Abstract: A method for inserting an intervertebral artificial disc is provided with the intervertebral disc including a first endplate having a plurality of protrusions for attaching to an adjacent vertebrae and an extension portion extending towards a second adjacent vertebrae. A second endplate is provided with a plurality of protrusions for attaching to a second adjacent vertebrae and an extension portion extending towards the first adjacent vertebrae. A flexible member having an upper portion and a lower portion and a slider plate positioned within the upper portion of the flexible member is also provided. The extension portion of the first endplate is adapted to fit within a first cavity in the upper portion of the flexible member and the extension portion of the second endplate is adapted to fit within a second cavity in the lower portion of the flexible member.

Abstract: A device is disclosed for reducing a vertebral compression fracture, comprising a superior end plate and an inferior end plate disposed along a vertical axis. The superior end plate and the inferior end plate are slidably separable in a vertical direction along the vertical axis. An interior chamber is provided in fluid communication with a port extending from an exterior to the interior chamber. The device is deployable within a vertebral body and expandable within the vertebral body by injecting a flowable material into the interior chamber thereby displacing the superior and inferior end plates along the vertical axis.

Abstract: Intervertebral implants for implanting into an intervertebral space are provided. The implants can comprise one or more layers that are operably attached to one another. An implant can comprise a first layer having a first mating surface that mates with a second mating surface of a second layer. The first mating surface and the second mating surface can have features that allow them to complement each other. The implants can include one or more bore holes for receiving a fixation member. The bore holes can be horizontal, vertical or diagonal. In some cases, the bore holes will be blind bore holes.
