Patent number: 11986394Abstract: The present disclosure provides knee prostheses that replicate at least a portion of the function of an individual patient's anterior cruciate ligament (ACL). An exemplary knee prosthesis includes a femoral component configured to be implanted on the distal end of the patient's femur and a tibial component configured to be implanted on the proximal end of the patient's tibia. In extension, the femoral component and the tibial component may cooperate to limit anterior movement of the tibial component relative to the femoral component. In flexion, the femoral component may be free to rotate relative to the tibial component.Type: GrantFiled: April 24, 2020Date of Patent: May 21, 2024Assignee: Zimmer, Inc.Inventors: Adam H. Sanford, Vincent A. Webster, Dwight T. Todd, Anthony Romano, Christopher M. Byrd, Jody L. Claypool, Raymond C. Parisi

Patent number: 11771560Abstract: A modular reverse shoulder orthopaedic implant includes a humeral stem component and a separable fracture epiphysis component having a number of suture holes formed therein. The fracture epiphysis component is configured to receive a number of sutures for surgically repairing a proximal humeral fracture.Type: GrantFiled: October 19, 2021Date of Patent: October 3, 2023Assignee: DEPUY SYNTHES PRODUCTS, INC.Inventors: Jason M. Chavarria, Dwight T. Todd, Didier Poncet

Publication number: 20230113335Abstract: According to one example, a tibial prosthesis that can include a tibial bearing component, tibial baseplate, an insert and a fastener. The tibial bearing component can have medial and lateral proximal articular surfaces and an opposing distal surface. The tibial bearing component can define at least one recess therein with the recess having an opening at a periphery of the tibial bearing component. The tibial baseplate can be coupled to the tibial bearing component on the proximal surface thereof and having a distal surface configured to be disposed on a resected proximal surface of a tibia. The insert can be configured to be disposed within the recess and can engage the tibial baseplate and the tibial bearing component. The fastener can be insertable into the tibial bearing component and can be configured to retain the insert to the tibial baseplate.Type: ApplicationFiled: December 14, 2022Publication date: April 13, 2023Inventors: Brian D. Byrd, Kathleen Macke, Dwight T. Todd, James D. Wernle, Vanessa Croll, Jeff Blaylock, Abraham P. Habegger

Patent number: 11324598Abstract: Methods are disclosed for designing a tibial implant to minimize cortical impingement of a keel or other fixation structure when the tibial implant is implanted in the tibia bone. The design of the keel or other fixation structure on the tibial baseplate can be based on determining a common area between defined cancellous regions of at least two tibia bones. Methods are disclosed for designing a femoral component having a stem extension such that the stem can be sufficiently placed in the diaphysis of the femur when the femoral component is implanted. The method includes determining a canal axis in a femur that creates adequate engagement between a reamer and the diaphysis of the femur.Type: GrantFiled: January 15, 2020Date of Patent: May 10, 2022Assignee: Zimmer, Inc.Inventors: Yifei Dai, Christine Schaerer, Dwight T. Todd, Jeffrey E. Bischoff, Adam D. Henderson
