  • Patent number: 7887537
    Abstract: An external fixation system having a fixation component (20) comprising: a) a first capture member (24) adapted to capture a second element (26) of an orthopedic fixation system; and (b) a second capture member (22) adapted to capture a second element (28) of an orthopedic fixation system and coupled to the first capture member such that the coupling (86,94,110) allows the first capture member and the second capture member to rotate about three axes relative to each other element and move along that axis; wherein the coupling is adapted to secure the first and the second capture members from rotation with an activation (100); and wherein the second capture member is adapted to capture the second element by snapping onto the second element from substantially perpendicular to longitudinal axis of the second element

  • Publication number: 20030036761
    Abstract: This invention relates to methods, devices, and systems for preventing complications, including for example, infection associated with any percutaneous or external fixation of bones by placing a pharmacological sleeve over an external fixation element. The pharmacological sleeve may be comprised of a polymer sleeve having one or more internal splines along at least part of the inner surface of the sleeve. The sleeve may be suffused or coated on any or all surfaces with a pharmacological coating which allows accumulation of drugs in the tissue surrounding the external fixation element, thereby reducing potential complications.

  • Patent number: 5968046
    Abstract: A method and apparatus for reducing a fracture provides a provisional fixation pin to provisionally affix the bone plate to the bone prior to the installation of the bone plate with permanent attachment, such as bone screws. The method and apparatus of the present invention will maintain some reduction without significantly compromising the bone. The method utilizes a provisional fixation pin having an upper or proximal unthreaded shaft section and a lower externally threaded shaft section. A cutting tip is provided at the extreme distal end of the fixation pin. In between the proximal and distal sections is an enlarged diameter section that has an annular surface sized and shaped to conform to the countersunk surface of openings in the bone plate.
