  • Patent number: 6488713
    Abstract: A hip joint prosthesis having a retainer for a modular bearing in an acetabular cup and also having a bearing extraction member mounted in the cup for removal of a primary bearing. One embodiment of the bearing extraction member is a plug which is located in a hole provided in the acetabular cup and which is covered by a polyethylene bearing directly molded into the cup. The plug is an internally threaded plug with a convex head and is adapted to be pulled out of its resting position in the cup with the aid of an extraction tool such that the head of the plug exerts a removal force on the molded polyethylene bearing, causing it to disengage from the cup.

  • Patent number: 6482232
    Abstract: An apparatus and method for tibial fixation of a soft tissue graft includes a body having a first side and a second side. A first plurality of spikes extend from the second side of the body each having a first length. A second plurality of spikes extend from the second side of the body each having a second length where the first length is longer than the second length. The first plurality of spikes are operable to engage the bone without the second plurality of spikes substantially engaging the soft tissue graft to permit proper tensioning of the soft tissue graft. The method includes forming a tunnel in a bone and forming a counterbore substantially perpendicular with the tunnel. The soft tissue graft passes through the tunnel and the counterbore and is secured within the counterbore with an apparatus which is nested within the counterbore.

  • Patent number: 6458161
    Abstract: An acetabular prosthesis for implantation in an acetabulum and surrounding pelvis is described. The acetabular prosthesis includes an acetabular cup having a substantially concave inner surface and a substantially convex outer surface, wherein an area defining a groove is located on the outer surface of the acetabular cup. An optional spacer member, having a raised ridge formed on a surface thereof, slidably engages the groove. The spacer provides augmentation and load bearing support in cases where bone tissue loss has occurred in and around the acetabulum. A fastener, such as a surgical screw, is used to secure the acetabular cup, and the optional spacer, to the acetabulum. At least one attachment member is integrally formed with the acetabular cup for fastening to a surface of the pelvis, such as the ilium and/or the ischium. Another optional spacer member is provided for the attachment member to provide augmentation around the attachment points on the pelvis.

  • Patent number: 6361731
    Abstract: A method for forming a temporary orthopedic implant used in an orthopedic surgical procedure. The method includes mixing bone cement during a surgical procedure. An appropriately sized cement mold is selected which is translucent and includes an input port. The cement mold is filled with bone cement to form the temporary implant. A surgeon determines that the cement mold is fully filled by viewing through the translucent cement mold. The surgeon further fills the cement mold by directing a nozzle within the input port of the cement mold. The cement mold may further be pierced to relieve any air pockets formed in the cement mold. The temporary implant is then subsequently implanted into a patient. The temporary implant may also include a re-enforcement member included into the temporary implant.

  • Patent number: 6338734
    Abstract: An implant for use in fixing an resected portion of a bone to a proximal portion of the bone. The implant includes an anatomically shaped plate member having a generally straight first portion and a second portion. The first portion has a bone receiving groove on its inner side and at least one lower wire receiving groove on its exterior side. The bone receiving groove is adapted to receive a generally straight portion of the proximal portion of the bone. The second portion is coupled to the first portion at a first end and terminates at a distal end in at least one inwardly directed hook-shaped member. The second portion is curved to generally match the contour of an end portion of the bone. The hook-shaped member is adapted to abut the resected portion of the bone to prevent the resected portion from migrating from the straight portion of the proximal portion of the bone.

  • Patent number: 6286670
    Abstract: A container for containing first and second components that are to be mixed with one another. The container includes a divider and a barrier mechanism. The divider isolates a first compartment containing the liquid component from a second compartment for containing the powder. A vacuum source is placed in fluid communication with the second compartment. The vacuum source is of sufficient size and pressure to cause the first component to be drawn through the second component to ensure thorough admixing of the first and second components after the integrity of the divider has been compromised. The barrier mechanism is disposed between the second compartment and the vacuum source and forms a barrier to resist infiltration of the first component but permit the passage of gas into the vacuum source. A method for forming a compound using the container of the present invention is also provided.
