  • GRAFT ANCHOR SYSTEM AND METHOD
    Publication number: 20130261677
    Abstract: A graft anchor has first and second arms each having a leading end, a trailing end, an inner surface, and an outer bone contactable surface. The graft anchor also has a resilient bridge extending between the inner surface of the first arm and the inner surface of the second arm to space apart the first arm and the second arm. The resilient bridge defines a graft receiving pathway between the inner surfaces of the first and second arms. The resilient bridge also defines a deflection point about which a force acting upon the resilient bridge in a direction from the leading end to the trailing end causes the leading ends of the first and second arms to move toward one another and the trailing ends of the first and second arms to move away from one another.

  • Bone cement system for bone augmentation
    Patent number: 8546462
    Abstract: A bone cement is provided that includes a solid component and a liquid component. The solid component and liquid component are mixed together to form the bone cement. After completion of the solid and liquid component mixing, the bone cement has an initial viscosity effective for manual application or manual injection onto or into a targeted anatomical location, e.g., bone, and the cement has stable viscosity range that over both time and temperature is effective for uniformly filling the targeted anatomical location, for example an osteoporotic bone or a fractured vertebral body, with minimal to no leakage of the cement from the targeted anatomical location. Additionally, both the initial viscosity and the stable viscosity of the bone cement are within a range that renders the bone cement effective for injection with a manually operated syringe or multiple syringes.

  • Joint Prosthesis With Infinitely Positionable Head
    Publication number: 20130253659
    Abstract: A joint prosthesis includes a bone engaging portion, such as a stem, and articulating component, such as a humeral head, and an insert component that supports the articulating component and is removable from the stem. A mating component mates with the humeral head and is configured to engage the insert component at adjustable angles according to the anatomy of the patient's joint. In a revision surgery, the stem remains within the patient's bone while the insert component is removed with the mating component and humeral head fixed to the insert component. A new insert component may be prepared with the mating component and humeral head oriented to replicate the angular orientation of the previous prosthesis. The new insert component is then mounted within an insert cavity in the implanted stem and rigidly fastened to complete the revision.
