Assemblies, systems, kits, and methods related to an endoprosthetic rotating hinge assembly. The exemplary embodiments disclosed herein can comprise a preassembled rotating hinge subassembly having a hingedly rotating femur box configured to be mechanically engaged to a femoral component via a femur fastening mechanism, the femur fastening mechanism being non-axially aligned with a tibial axis of rotation when the knee is in flexion or extension.

An expandable implant may include a superior endplate and an inferior endplate hingedly coupled together. 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. The implant may further include a proximal plate having a superior engagement surface and an inferior engagement surface. At least one shim may be disposed within the at least one tracks of the superior endplate and interior endplate, and the at least one shim may define an angle of inclination between the superior endplate and interior endplate. The at least one shim may be insert between the superior and inferior endplates to effectuate expansion and angulation. In various embodiments, the superior endplate may be supported by the superior engagement surface and the inferior endplate may be supported by inferior engagement surface.

An inclination guide for use with an implant insertion tool during a surgical procedure includes a unitary body having a clip configured to be coupled to a mounting surface of the implant insertion tool, an elongated riser extending from the clip, and an elongated indicator extending from the elongated riser to a distal end. Such a design allows for an inexpensive and lightweight inclination guide that may be easily and quickly adjusted after assembly.

The present invention relates to an anchoring system for attaching a prosthesis to a human body, comprising: an anchoring element, an abutment, an abutment screw for attaching the abutment to the anchoring element, the anchoring element comprises a connection area for the abutment, the connection area comprising a press-fit portion such that the abutment is attached to the anchoring element in the connection area by a press-fit connection, wherein the connection area comprises an anti-rotation geometry and the abutment comprising a corresponding mating anti-rotation geometry proximal to the press-fit portion, and where in the connection area comprises a conical portion proximal to the anti-rotational geometry forming a mating geometry for a corresponding conical portion in the through-hole of the abutment.

Methods and devices are disclosed for treating the vertebral column. An implant for treating the spine is provided comprising at least two articulations between the spacer and the bone facing surface of the fixation plate. Another implant for treating the spine is also provided, comprising two or more fixation plates attached to a spacer with two or more articulations, wherein the fixation plates are independently movable.

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 spinal fixation device includes an outer housing and an end plate assembly coupled with the outer housing. The outer housing defines an aperture and a longitudinal axis. At least a portion of the end plate assembly is slidably received within the outer housing. The end plate assembly includes a first end plate configured to engage a vertebral body, wherein the end plate assembly is selectively movable between a first position in which the first end plate is spaced apart from the outer housing and a second position in which the first end plate is adjacent the outer housing. Further, the first end plate is selectively adjustable to an angular orientation of a plurality of angular orientations with respect to the longitudinal axis of the outer housing.

An implant stabilizes two adjacent bones of a joint, while enabling a natural kinematic relative movement of the bones. Support components are connected to each bone of the joint, and a flexible core is interposed between them. The core and at least one of the support components are provided with a smooth sliding surface upon which the core and support component may slide relative to each other, enabling a corresponding movement of the bones. The surfaces may have a mating curvature, to mimic a natural movement of the joint. The core is resilient, and may bend or compress, enabling the bones to move towards each other, and or to bend relative to each other.
