Publication number: 20160302870Abstract: Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.Type: ApplicationFiled: July 7, 2015Publication date: October 20, 2016Inventors: Zachary Christopher Wilkinson, Ryan Lloyd Landon, Brian William McKinnon

Patent number: 9233002Abstract: Systems, methods and devices for tensioning posterior crucial ligaments during cruciate or bi-cruciate ligament-sparing arthroplasty. Non-limiting examples of such systems may include at least one series of tibial inserts of equal size; the at least one series of tibial inserts having at least one set of tibial inserts of equal thickness. The at least one set of tibial inserts of equal thickness may include at least two tibial inserts having different geometries in a posterior portion, the different geometries being configured to change the tension in the posterior cruciate ligament (PCL). The different geometries in the posterior portions of the tibial inserts are configured so as to allow the posterior cruciate ligament to be tensioned or loosened independently of the tibial insert thickness and/or size.Type: GrantFiled: July 23, 2013Date of Patent: January 12, 2016Assignee: Smith & Nephew, Inc.Inventors: Nathaniel Milton Lenz, Zachary Christopher Wilkinson

Publication number: 20150088265Abstract: Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. Other embodiments provide improved lateral and/or medial inserts having a mesial lip that helps relieve and/or prevent impingement between the femoral component and the tibial eminence. Other embodiments provide improved femoral components having various chamfers to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.Type: ApplicationFiled: December 1, 2014Publication date: March 26, 2015Applicant: SMITH & NEPHEW, INC.Inventors: Nathaniel Milton Lenz, Richard Michael Smith, Zachary Christopher Wilkinson, Brian William McKinnon, Abraham Biglari Salehi, Jonathan Kirk Nielsen, Michael D.

Patent number: 8926709Abstract: An orthopaedic implant including a base portion and first and second transverse portions extending transversely from the base portion to thereby define an inner region of the implant sized for receipt of an end portion of a bone therein. The implant further includes at least one anchor structure projecting from the base portion and sized and configured for receipt within an opening formed in the end portion of the bone. The anchor structure extends along a longitudinal axis and includes a proximal end attached to the base portion and an opposite distal end, and further includes a tapered outer surface that inwardly tapers in a proximal-to-distal direction along the longitudinal axis. In one embodiment, the anchor structure also includes one or more grooves extending into the tapered outer surface, with a flowable material positioned about at least a portion of the tapered outer surface and positioned within the grooves, and with the flowable material configured to cure to a hardened state.Type: GrantFiled: August 11, 2011Date of Patent: January 6, 2015Assignee: Smith & Nephew, Inc.Inventors: Nathaniel Milton Lenz, Zachary Christopher Wilkinson
