Publication number: 20150282820Abstract: A patella drill guide includes a base portion rotatably mounted on a bone-gripping component. A trial portion with a contoured articulation surface is above the base portion. The base portion and trial portion have aligned drill guide bores. The base portion and trial portion can be rotated together on the bone-gripping component to optimize the positions of the drill guide bores with respect to the patella surface, thereby optimizing the locations of the mounting pegs of the patella implant component on the patella to optimize the orientation of the patella implant component. The base and the bone-gripping component may be unitary so that the entire assembly rotates on the patella about the central longitudinal axis of the bone-gripping component.Type: ApplicationFiled: June 11, 2015Publication date: October 8, 2015Applicant: DEPUY (IRELAND)Inventors: RICHARD SPENCER JONES, ABRAHAM P.

Patent number: 9144498Abstract: A modular orthopaedic implant system has first, second and third implant components. Two of the components have bores and the third component has a post. The third component can be assembled with either the first or second components with the post received in the respective bore of the other component. When assembled, the length of the post received within the bore of one of the components is greater than the length of the post received within the bore of the other component. The fatigue strength of the assembly with a greater length of the post received within the bore is greater, and this assembly can be used where such greater fatigue strength is needed and the other assembly can be used where a lesser fatigue strength is needed. Since the third component that is used in both assemblies may be the same, inventory may be reduced.Type: GrantFiled: March 15, 2013Date of Patent: September 29, 2015Assignee: DEPUY (IRELAND)Inventors: Michael A.
