Patent number: 8460393Abstract: An implant for a hip can include a lateral augment adapted to be coupled to a lateral side of a femoral body implant. The lateral augment can include a body portion having a first surface, a second surface opposite the first surface, and a protrusion extending from the second surface. The protrusion can have a shape adapted to mate with a complimentary shaped recess formed in the lateral side of the femoral body implant. An aperture can be positioned in the body portion and extend through the protrusion. A fastener can be received through the aperture and adapted to be threadably secured to the lateral bore. The fastener can be configured to have a length sufficient to pass through a portion of a greater trochanter for securing the portion of the greater trochanter and the lateral augment to the femoral body implant.Type: GrantFiled: March 5, 2010Date of Patent: June 11, 2013Assignee: Biomet Manufacturing Corp.Inventors: Aaron P. Smith, Tyler D. Witt, Hugh Apthorp, Keith R. Berend, Andrew Freiberg, John Barrington, David R. Brown

Publication number: 20130103038Abstract: Systems, devices, and methods are provided for measuring forces in the space of a knee during surgery. Such forces can be caused by tension in the ligaments of the knee. A femoral member is engaged with a distal femur. While the knee is flexed, partially extended, or fully extended, a force sensor and a gauge shim can be placed in the gap between the femoral member and the tibial plateau to measure the forces therebetween. The force sensor provides an accurate and quantifiable measurement of force, making knee replacement surgery and ligament tension balancing more accurate, standardized and repeatable. The force sensor comprises an elongate housing which comprises a thin force sensing distal portion and a proximal handle portion.Type: ApplicationFiled: December 10, 2012Publication date: April 25, 2013Inventors: Michael G. Fischer, Andrew Sizelove, Keith R. Berend, David Murray

Patent number: 8398646Abstract: An orthopedic device for preparing a knee joint for a prosthesis in a patient includes a femoral alignment guide. The femoral alignment guide has a patient-specific three-dimensional curved inner surface preoperatively configured from medical image scans of the knee joint of the patient to nestingly conform and mate and match only in one position to a corresponding three-dimensional femoral surface of a joint surface of the patient. The femoral alignment guide has a first guiding aperture corresponding to a distal portion of the femoral surface and a second guiding aperture corresponding to an anterior portion of the femoral surface.Type: GrantFiled: November 23, 2011Date of Patent: March 19, 2013Assignee: Biomet Manufacturing Corp.Inventors: Robert Metzger, Keith R. Berend, Michael E. Berend, Adolph V. Lombardi, Jr., Lance D. Perry, Ryan J. Schoenefeld

Publication number: 20110257758Abstract: A modular femoral hip joint prosthesis can include a proximal femoral body having a distal end and a proximal end. The proximal end can be adapted to mate with a femoral head. A femoral stem can have a proximal section and a distal section. The femoral stem can be adapted to matingly connect with the distal end of the proximal femoral body. The proximal section can have a porous metal coating that is adapted to facilitate bony ingrowth. The distal section can have at least one spline formed along an outer surface.Type: ApplicationFiled: March 2, 2011Publication date: October 20, 2011Applicant: Biomet Manufacturing Corp.Inventors: Aaron P.
