  • Patent number: 8894716
    Abstract: A method of orienting a femoral head member of an implant relative to an acetabular member positioned in the acetabulum including implanting a femoral stem of an implant within an intramedullary canal of a femur, inserting an acetabular member in the acetabulum, positioning a femoral head member of the implant at least partially in the acetabular member with the femoral head member including a curved articulating surface and a plurality of indicia on the curved articulating surface, and orienting the femoral head member relative to the acetabular member and generally aligning one of the indicia on the curved articulating surface with an alignment feature of the acetabular member to signify an orientation of the femoral head member relative to the acetabular member.

  • Patent number: 8828009
    Abstract: Implants, surgical methods, and instrumentation for treating femoroacetabular impingement. In some embodiments, implants are provided or formed on the acetabulum to replicate the anatomy of the acetabulum (e.g., the acetabular rim and/or labrum, the bearing surface in the acetabulum, cartilage in the acetabulum, etc.). Also provided are embodiments of materials and instruments for use in installing and/or forming such implants on the acetabulum. Further provided are embodiments of guide jigs for use in preparing the acetabulum to receive such implants.

  • Patent number: 8751198
    Abstract: A method for forming an implant for a bone including the steps of generating a first general shape for the implant having a length extending along a long axis of the bone, determining an area moment of inertia of a cross section of the implant, determining an area moment of inertia for a cross section of bone coplanar to the cross section of the implant, calculating a percent stress shielding from the area moments of inertia of the implant and the bone, comparing the calculated percent stress shielding to a preset threshold, and iteratively generating additional general shapes for the implant by locally adjusting the cross section of the implant until the calculated percent stress shielding meets the preset threshold.

  • Patent number: 8491664
    Abstract: An apparatus for orienting a prosthetic femoral head relative to an acetabulum comprises a femoral stem and a femoral head member. The femoral stem is configured to be received within the intramedullary canal of a femur. The femoral head member is configured to couple to the femoral stem and further configured to be received in the acetabulum. The femoral head member further comprises an indicia configured to orient a relative position of the prosthetic femoral head to the acetabulum such that the indicia signifies proper relative position of the prosthetic femoral head in the acetabulum.

  • Patent number: 8425526
    Abstract: An adjustable impactor for a tool comprises a handle, a first link, and a second link. The first link is pivotably attached to the handle. The second link is pivotably attached to the first link. The second link has a connector configured to attach to the tool. A method for impacting an orthopaedic component inside a surgical cavity includes a step for pivoting a first link relative to a handle. Another step pivots a second link relative to the first link. The first and second links are locked. A step attaches a tool to the second link. An impacting step impacts the handle such that the handle transmits the force from the impact through the first and second links to the tool.
