The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In one embodiment, the fusion device includes a body portion, a first endplate, and a second endplate, the first and second endplates capable of being moved in a direction away from the body portion into an expanded configuration or capable of being moved towards the body portion into an unexpanded configuration. The fusion device is capable of being deployed and installed in both configurations.

Apparatus and methods for providing spinal percutaneous delivery of an implant that can rigidly fixate the spinous process of a first superior bone and a second inferior bone of a functional spinal unit. In one aspect, the device comprises two bone abutment members connected via an interconnecting member. In another aspect, the method comprises implanting at least two spinal implant apparatus within a target disc space via an implantation apparatus. In another aspect, a placement instrument comprising an implant delivery segment, an anchor segment, and an articulating arm is disclosed.

The present invention provides an expandable fusion device capable of being installed inside an intervertebral disc space to maintain normal disc spacing and restore spinal stability, thereby facilitating an intervertebral fusion. In an exemplary embodiment, the present invention provides an intervertebral implant. The intervertebral implant may be configured to transition from a collapsed configuration having a first height and a first width to an expanded configuration having a second height and a second width.

An intervertebral implant can include a core and a flexible end plate. The core can have a core body that is elongate along a first direction and defines first and second outer surfaces. The flexible end plate can define an inner surface and an opposed bone facing surface that is configured to abut a vertebral body. The flexible end plate can be coupled to the core such that at least a portion of the inner surface faces the first outer surface and is spaced from the first outer surface. The flexible end plate is configured to resiliently flex toward a compressed configuration such that as the flexible end plate flexes toward the compressed configuration, a first end moves relative to the core along the first direction and the portion of the inner surface moves toward the first outer surface.

An acetabular hip implant and method includes an acetabular shell component having a first feature and a first insert having a second feature that cooperates with the first feature of the acetabular shell component and further includes a third feature. The implant further includes a second insert having a fourth feature that cooperates with the third feature of the first insert and further includes a fifth feature. A femoral head component includes a sixth feature that cooperates with the fifth feature. Interaction between the first and second features, between the third and fourth features, and between the fifth and sixth features mechanically constrains the acetabular hip implant to prevent dislocation of the femoral head during rotation.

An orthopedic system that includes a first augment that has a body and a first biasing member projecting from the body. The body has a first and second face. The first and second faces are separated by a thickness of the augment. The system also includes a femoral prosthesis that has an articular side that defines condylar portions and a bone-facing side opposite the articular side. The bone facing side defines an augment opening that is sized to receive the augment therein. When the first augment is received within the augment opening, the first biasing member presses directly against the femoral prosthesis so as to retain the body within the augment opening.

An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.
