Specifically, a hip surgery method is disclosed in which an image of a patient's femur can be obtained and used to design and prepare a mold that contains an aperture for guiding a drill at the desired location and angle. During surgery the mold can be quickly and accurately positioned on the exposed femur head. Then, a drill bit can be inserted through the aperture and an opening for a pin can be drilled into the femur head. The mold can have a unique contoured surface adapted to fit to the femur head in a single unique position such that the opening is made in a unique desired position. The apparatuses and methods facilitate faster, more accurate surgery and are less invasive.

  • Patent number: 8795381
    Abstract: Methods and apparatus of the present invention provide for orthopaedic replacement of the hip while substantially preserving muscles and soft tissues around the hip joint resulting in reduced healing time and decreased risk of dislocation following the procedure. In an exemplary embodiment, an intramedullary rod 1502 is inserted longitudinally into the femur. A prosthetic femoral neck 3102 is then inserted from a point along the side of the patient's body and into the side of the femur and through a pre-existing lateral bore in the intramedullary rod 1502 and through the remainder of the femur to join the prosthetic femoral head 1102. The methods and apparatus include structures and techniques for fixing the prosthetic femoral neck 3102 in relation to the intramedullary rod 1502.

  • Patent number: 8747482
    Abstract: An orthopaedic prosthesis includes a curved outer surface configured to abut a patient's bone when the orthopaedic prosthesis is implanted therein. The outer surface may or may not be electrically conductive. A channel is defined in the outer surface in which one or more electrical conductors are positioned. A switch is positioned at a first location on the outer surface and is configured to establish an electrical connection between the electrical conductor and the outer surface (e.g., an electrical trace) and/or another electrical conductor when the first location of the outer surface is pressed against the patient's bone. The switch may be embodied as an end of the electrical conductor or a more complex switch such as a push-button type switch.

  • Patent number: 8734457
    Abstract: An instrument for use in a joint replacement procedure includes a trial head that corresponds to the head of an orthopaedic joint component having an upper surface defined by a curved surface and a bore formed in a lower surface and a trial connector for connecting the trial head to a stem part of the orthopaedic joint component which is intended for location in the intramedullary cavity of a bone. The trial connector can be fitted into the bore in the trial head at a variable angular orientation.

  • Patent number: 8709092
    Abstract: A variety of options for for fracture fixation after total hip arthroplasty or total knee arthroplasty. The ability to pre-engineer fracture fixation contingent solutions into femoral or tibial components provides a distinct clinical advantage in the planning and execution for periprosthetic fracture fixation. Methods and apparatus include targeting devices allowing for intimate association of fixed angle locking screws in pre-drilled holes in an existing prosthetic, femoral nail, or other components including additional fixation components. Such apparatus and methods further include alignment devices and other components to allow for ease of repair of periprosthetic fractures utilizing the pre-engineered solutions.

  • Patent number: 8702804
    Abstract: The present teachings are directed to a shoulder prosthesis having an adjustable radial offset and/or angular inclination provided by relative rotation of an adapter interdisposed between a stem and a head. In one example, a prosthesis has a stem having a first longitudinal axis. The prosthesis can also include an adaptor including a first taper. The first taper can have a first taper axis. The prosthesis can include a head supported by the adaptor. The head can be selectively oriented and then coupled to the first taper and the combination can be selectively orientated and the coupled to the stem.
