  • Publication number: 20130331843
    Abstract: A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.

  • Publication number: 20130123788
    Abstract: An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a tensioning bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.

  • Patent number: 8337498
    Abstract: A milling tool system for accurately preparing a portion of the tibia preparatory to making femoral resections. The milling too system provides a minimally invasive procedure to provide an aperture within an exposed surface of the tibia, the aperture then being used as a referencing surface to accurately resect the femur. Once the femur resections have been made, the remaining uncut portions of the tibia are exposed and easily accessible for the tibial resections.

  • Publication number: 20110298806
    Abstract: Systems and methods for providing graphical information regarding one or more patients' medical information are described. The graphical information can be used in various methods of graphical comparison, including graphical diagnoses, graphical comparison between patients, over time with a single patient, and/or over time with and/or between multiple patients. The graphical information can be used in place of and/or in conjunction with existing methods and systems for conveying medical information, including one or more textual methods and systems. The graphical information is provided electronically to any electronic or computer device or is provided in hard copy, such as a part of a patient's chart. The use of graphical patient medical information permits rapid and improved conveyance of information, and improves recognition and understanding of the most relevant medical information.

  • Patent number: 7927336
    Abstract: An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a torque bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting.

  • Patent number: 5803905
    Abstract: A surgical camera assembly and method for visually producing an operative field with enhanced focal illumination is disclosed as including a retaining assembly operably disposed in connection with a light source. Preferably, the retaining assembly provides a sterile surface for orienting the light source in relation to the operative field and includes a means for retaining a first end of camera lens. Removably disposed in operable engagement with the retaining assembly, the camera lens comprises an elongated body and a variable focus and zoom capability for producing visual images of the operative field. The elongated body of the camera lens is removably introduced within a channel formed in the body of a housing assembly. In preferred relationship, the housing assembly provides a sterile surface for manually adjusting the variable focus and zoom capability of the camera lens for purposes of enhancing the visual images of the operative field produced by the lens.
