Publication number: 20240000576Abstract: A tibial spacer paddle comprises a spacer block comprising opposing bearing surfaces, an alignment slot extending into the spacer block; and a handle extending from the spacer block. The spacer block can include feet for passively engaging the femur or pegs for actively engaging a femoral component so that the spacer block is linked to the femur while the tibia rotates. A tibial spacer system comprises a provisional component having an alignment tab extending from a body and an alignment indicator located on the body, a femoral component and a pin extending from the femoral component. The pin can engage the alignment tab so that the provisional component is linked to the femur while the tibia rotates. In addition to or alternatively to the alignment tab and pin, the provisional component can include a tibial plate that can be rotationally connected to the provisional component.Type: ApplicationFiled: September 13, 2023Publication date: January 4, 2024Inventors: Brian D. Earl, Alexander P. Wolfe

Patent number: 10646237Abstract: Methods, systems and apparatuses including an orthopedic assembly are disclosed. The orthopedic assembly can include a femoral component and a guide. The femoral component can be configured to engage a resected distal surface of a femur. The femoral component can have a box cutout configured to provide access to a distal centrally located region of the femur. The box cutout can be disposed between a medial condyle, a lateral condyle and an anterior portion of the femoral component. The guide can be configured to selectively connect to the femoral component at one or more locations and can be spaced from the femur. The guide can have an opening therethrough configured to provide access to the box cutout and the distal centrally located region of the femur. One or more surfaces of the guide can define the opening, each of the one or more surfaces can be configured to act as a guide surface.Type: GrantFiled: December 12, 2016Date of Patent: May 12, 2020Assignee: Biomet Manufacturing, LLCInventors: Alexander P. Wolfe, Duke A. Fox, Nicholas William Hutchison

Publication number: 20200054351Abstract: A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.Type: ApplicationFiled: October 23, 2019Publication date: February 20, 2020Inventors: Jason D. Meridew, Tyler D. Witt, Ryan John Schoenefeld, William Jason Slone, Adolph V. Lombardi, Jeffrey H. Nycz, Matthew D. Munsterman, Alexander P. Wolfe, Tamon Kabata, James Nairus, John C. Clohisy
