Patent number: 10136933Abstract: The present disclosure provides, in certain aspects, unique methods and systems for connecting orthopedic components. In some forms, a male-type projection of a first orthopedic component is securely lodged within a female-type aperture in a second orthopedic component. In one embodiment, the projection, while received through a proximal entryway in the aperture, includes a first longitudinal region with deformed surface elements that provide a first securing zone within the aperture and a second longitudinal region with deformed surface elements that provide a second securing zone within the aperture. The first securing zone is located proximate the distal end of the projection, and the second securing zone is located proximate the proximal entryway of the aperture.Type: GrantFiled: October 25, 2013Date of Patent: November 27, 2018Assignee: Zimmer, Inc.Inventors: Steven L. Meulink, Paul J. Conrad

Patent number: 9987147Abstract: A method for selecting modular neck components for hip implants based on independent variables associated with physical characteristics of the implant, including leg length, offset, and anteversion. During surgery, the surgeon may be confronted with a need to change a preoperatively-chosen modular neck. For example, the surgeon may desire a change in at least one of the variables, e.g., leg length, offset, and/or anteversion. The present method allows the surgeon to quickly and easily select a different modular neck based on an evaluation of one of the variables without requiring reevaluation of the other variables. The method may include preoperative planning in which a template including a grid coordinate system is used.Type: GrantFiled: November 21, 2012Date of Patent: June 5, 2018Assignee: Zimmer, Inc.Inventor: Steven L. Meulink

Patent number: 6514288Abstract: The present invention provides an improved prosthetic stem for implantation in a bone. Specifically, the present invention provides a prosthetic femoral stem having a strengthening rib protruding from the substrate thereof and being flush with a porous coating formed thereon. The strengthening rib is advantageously positioned so as to increase the cross-sectional moment of inertia of the prosthetic femoral stem and thereby decrease the stress on the anterio-lateral surface of the femoral stem. A protrusion in accordance with the present invention may also be utilized with a prosthetic femoral stem absent a porous coating. In such an embodiment, the height of the protrusion is such that the protrusion will be surrounded by the cement mantle formed when the prosthetic femoral component is cemented in a femoral canal.Type: GrantFiled: February 23, 2001Date of Patent: February 4, 2003Assignee: Zimmer, Inc.Inventors: Steven L.
