  • Publication number: 20080215157
    Abstract: A provisional prosthetic system that replicates the characteristics of a corresponding, nonprovisional femoral prosthesis. The provisional prosthetic system may include a frame component and a shell component. The frame component of the provisional prosthetic system may be configured to be attached directly to a resected femur. In one exemplary embodiment, the frame component is impacted onto the resected femur to firmly seat therewith. Once the frame component is secured to the resected femur, a shell component of the provisional prosthetic system may be positioned on and secured to the frame component. In one exemplary embodiment, the frame component is made from a metallic material. This allows for the frame component to maintain the rigidity necessary to facilitate proper trialing. In another exemplary embodiment, the shell component is a plastic.

  • Publication number: 20080195222
    Abstract: A method for constantly controlling a direct application of pressure for bonding porous coatings to substrate materials used in orthopaedic implants. The direct pressure is applied to an interface between the porous coating and the substrate material via a pressure application mechanism unaffected by heat and air pressure conditions of the bonding process. The pressure application mechanism maintains a pressure on the implant which is constantly controlled throughout the bonding process.

  • Publication number: 20080147196
    Abstract: An assembly system configured to seat a first orthopedic component having either a male taper or a female taper with a second orthopedic component having the other of a male taper or a female taper. In one embodiment, the assembly system includes a taper seating connector having a fastener and a bushing moveable retained on the fastener. The fastener may be connected to the first orthopedic component and the bushing may be positioned adjacent the second orthopedic component. The corresponding tapers on the first and second orthopedic components may be configured to secure the first and second orthopedic components together. Thus, by exerting a sufficient force on the bushing, the bushing will move along the fastener, transferring the force to the second orthopedic component. In this manner, the corresponding tapers of the first and second orthopedic components may be seated.

  • Publication number: 20080147203
    Abstract: A provisional prosthetic system and the surgical methods for utilizing the same. In one embodiment, the provisional prosthetic system includes a keel and a plate configured to be secured to the keel. The keel may further include a body and at least one fin extending outwardly therefrom. The fin functions to prevent rotation of the keel once it is implanted within a bone. In one embodiment, the plate includes a captured screw having a flanged head and external threads. The captured screw is retained by the plate and configured to secure the plate to the keel. In this embodiment, the captured screw extends through an aperture in the plate. Further, the captured screw may be retained by the plate due to the interaction of the flange head and external threads of the captured screw with the top and bottom surfaces of the plate, respectively.

  • Publication number: 20080133023
    Abstract: The present invention relates to provisional prosthetic components for a medical device and the surgical methods for utilizing the same. In one embodiment, the provisional prosthetic component includes a first portion and a core. The first portion is capable of mating with another prosthetic component. The first portion of the provisional prosthetic component may have a scratch hardness which is less than the scratch hardness of the prosthetic component. This allows for the first portion to be placed in mating engagement with the prosthetic component without scratching or damaging the junction of the prosthetic component. Additionally, the core of the provisional prosthetic component may have a scratch hardness greater than the scratch hardness of the first portion of the provisional prosthetic component and/or a stiffness sufficient to minimize deflection of the provisional prosthetic component during trial reduction and range of motion testing.

  • Publication number: 20080097616
    Abstract: A constrained prosthetic knee having a modular hinge post and a rotating bearing. A cannulated hinge post is rotatably connected to the femoral component of the knee prosthesis so that a hinge post extension may be anteriorly positioned through the hinge post and into the tibial component of the knee prosthesis, after positioning of the femoral component in the femur and the tibial component in the tibia. The hinge post is preassembled to the femoral component so that such assembly is not required during the implantation procedure. A meniscal component forming the rotating bearing of the knee prosthesis is packaged together with the hinge post extension so that the appropriate hinge post extension is readily available. The meniscal component includes a mechanism for preventing lift off of the meniscal component from the tibial component, while allowing rotation of the meniscal component relative to the tibial component.

  • Publication number: 20080046091
    Abstract: An anchor for securing an implant within bone. In one embodiment, the anchor is used to aid in securing an acetabular cup within an acetabulum. The anchor may be implanted within an ischial defect of the pelvis, and is attached to an outer surface of the acetabular cup shell. The anchor is made at least in part of, and may be made entirely of, a porous metal material to facilitate the ingrowth of surrounding bone into the anchor for osseointegrating the anchor into the surrounding bone. The anchor may be secured to the acetabular shell by a screw fastener or by cement, for example. The anchor may be secured to the acetabular shell before the anchor and the acetabular shell are together implanted into the acetabulum, or the anchor may be implanted into the ischial defect, followed by seating the acetabular shell in the acetabulum and then securing the acetabular shell to the anchor.

  • Publication number: 20080027458
    Abstract: A blade plate, as well as instruments and methods for securing the blade plate to a bone to reduce a bone fracture. The blade plate includes a plate portion and a blade portion extending at an angle relative to the plate portion. The plate portion includes a plurality of holes for receipt of bone screws for securing the blade plate to the bone about the bone fracture. A strut screw, inserted through a hole in the plate portion, spans the angle between the plate and blade portions, and threadingly engages a hole in the blade portion to slightly draw the plate and blade portions together to compress and support the bone fracture. A pair of top screws are inserted through holes in the plate portion at angles with respect to the strut screw on either side of the strut screw. Additionally, the blade plate is designed to closely conform to the surface of the bone to minimize the gap between the bone and the blade plate.
