Patent number: 8751198Abstract: 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.Type: GrantFiled: September 20, 2007Date of Patent: June 10, 2014Assignee: Smith & Nephew, Inc.Inventors: David C. Kelman, Michael A. Croxton, Charles Wayne Allen, William L. Waltersdorff

Patent number: 8491664Abstract: 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.Type: GrantFiled: February 25, 2009Date of Patent: July 23, 2013Assignee: Smith & Nephew, Inc.Inventors: Stephen McMahon, Charles Wayne Allen, David C.

Patent number: 8425526Abstract: 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.Type: GrantFiled: October 17, 2007Date of Patent: April 23, 2013Assignee: Smith & Nephew, Inc.Inventors: William L. Waltersdorff, Charles Wayne Allen, Kevin W. Belew, Michael Scott McCaig
