Abstract: Embodiments of the disclosure provide a spinal stabilization rod useful for connecting a set of bone fasteners that can anchor a spinal stabilization system onto vertebral bodies. The spinal stabilization rod comprises rigid sections for coupling with bone fastener assemblies engaged in vertebrae and a flexible band for coupling the rigid sections. A bumper may be disposed around the rod to encase the flexible band. The spinal stabilization system may include a dampener.

Abstract: An inter-vertebral implant wherein at least one of the side walls defining a hole from the exterior of the implant to the fusion promotion cavity and having a posterior portion and an anterior portion, the side wall hole being elongated in a direction between the posterior and anterior ends of the side wall hole. In some embodiments, the side wall hole is tapered toward the posterior portion of the implant and can be tear drop shaped. In some embodiments the cephalad and caudal surfaces may be convex with radii of curvature which can be the same for all implant sizes. The surfaces may include teeth which can extend beyond a central cavity. A nose, tapered in the saggital and transverse planes may be included on the anterior end of the implant. Some embodiments also include a threaded hole (with a depth that can be the same for all implant sizes) and an adjoining slot for engaging an insertion instrument. Each of the portions of the implant can have the same length for all implant sizes.

Abstract: An offset trial stem system includes a baseplate and a trial stem. The trial stem has a main body portion and a baseplate connection portion. The baseplate connection portion is threadably attached to the baseplate, and is offset from, and connected to, the main body portion by a transition portion. A threaded member is provided for attaching the trial stem to the baseplate. The threaded member is mounted for reciprocating and rotating movement in the trial stem.

Abstract: An offset, press-fit tibial stem system includes a baseplate, a main body portion, a baseplate connection portion attached to the baseplate and being offset from, and connected to, the main body portion by a transition portion. The main body portion has a first centroidal axis passing therethrough and the baseplate connection portion has a second centroidal axis passing therethrough. The offset is such that the first centroidal axis and the second centroidal axis are slightly spaced apart and substantially parallel so as to each pass through the main body portion.

Abstract: A combination stem trial and broach includes a broach having a first attachment device at one end thereof. The first attachment device includes a first threaded member and a first orientation member. An elongated stem trial has a second attachment device at a first end thereof for engagement with the first attachment device. The second attachment device includes a second threaded member for connection with the first threaded member and a second orientation member for connection with the first orientation member.
