Patent number: 10342555Abstract: A patient specific guide block for a knee includes a plurality of bone interfacing portions and a cutting slot. The plurality of bone interfacing portions are configured to overlie portions of an end of a bone. The bone interfacing portions each have a surface that is generally a negative of the portion of the bone that the respective bone interfacing portion overlies. The bone interfacing portions are angularly offset from each other such that a first of the bone interfacing portions overlies an anterior portion of the bone, and a second of the bone interfacing portions overlies a portion of bone generally perpendicular to the anterior portion of bone. The cutting slot is oriented in a fixed position relative to the bone interfacing portions such that the cutting slot directs a cutting tool at a fixed angle and at a fixed depth relative to the bone interfacing portions.Type: GrantFiled: March 5, 2018Date of Patent: July 9, 2019Assignee: Smith & Nephew, Inc.Inventors: Abraham Biglari Salehi, David Timothy Mehl, Mark Ellsworth Nadzadi, Aashiish Agnihotri, Jason Sean Jordan

Patent number: 9532788Abstract: A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.Type: GrantFiled: May 12, 2015Date of Patent: January 3, 2017Assignee: Smith & Nephew, Inc.Inventors: Jason Sean Jordan, Michael Dean Hughes, Mark Ellsworth Nadzadi, Brian William McKinnon, Paul Charles Crabtree, Jr., David Timothy Mehl
