Patent number: 9718241Abstract: An orthopedic component having multiple layers that are selected to provide an overall modulus that is substantially lower than the modulus of known orthopedic components to more closely approximate the modulus of the bone into which the orthopedic component is implanted. In one exemplary embodiment, the orthopedic component is an acetabular shell. For example, the acetabular shell may include an outer layer configured for securement to the natural acetabulum of a patient and an inner layer configured to receive an acetabular liner. The head of a femoral prosthesis articulates against the acetabular liner to replicate the function of a natural hip joint. Alternatively, the inner layer of the acetabular shell may act as an integral acetabular liner against which the head of the femoral prosthesis articulates.Type: GrantFiled: January 16, 2014Date of Patent: August 1, 2017Assignee: Zimmer, Inc.Inventors: Kirt Case, Oludele O. Popoola, Robby Kissling, Brion R. Mimnaugh, Archie Newsome, Clarence M. Panchison, Dirk Pletcher, Randy Schlemmer, Zhibin Fang, Juan Vivanco, Alicia Rufner, John Knight

Patent number: 8663337Abstract: A process for forming a ceramic layer comprising a compound of a metal on a deposition surface of a workpiece comprises providing a reactive gas, selecting the amounts of a vapor of the metal and ions of the metal relative to each other, generating the metal vapor, and projecting an ion beam of the metal ions. The metal vapor, the metal ions, and the reactive gas form the ceramic layer with a desired structure. The process may include the step of controlling a deposition surface temperature. In one embodiment, the metal vapor comprises zirconium vapor and the ion beam comprises zirconium ions. The relative amounts of the zirconium vapor and the zirconium ions are selected to form a zirconia ceramic layer on the deposition surface. The zirconia may have multiple crystal phases that are formed according to a predetermined ratio.Type: GrantFiled: March 6, 2012Date of Patent: March 4, 2014Assignee: Zimmer, Inc.Inventors: Jeffrey P.

Patent number: 8142511Abstract: A prosthesis has prosthetic components principally comprising metallic materials, in which a portion of an articular interface between respective components is a metallic-nonmetallic interface. At least a portion of the articular surface of a femoral head may include a ceramic material defining an articulation zone, such as at a polar region of the femoral head, so that the ceramic articulates with a metallic acetabular liner. The area covered by the ceramic may be engineered to optimize the contact conditions between the femoral head and the acetabular liner, such as by providing two clearances therebetween. A relatively smaller, polar articulation clearance is defined by the gap between the ceramic coating and the metallic acetabular liner. A relatively larger, equatorial non-articulation clearance between the femoral head and the acetabular liner is defined by the gap between the portion of the femoral head not covered by the ceramic coating.Type: GrantFiled: April 19, 2010Date of Patent: March 27, 2012Assignee: Zimmer, Inc.Inventors: Oludele O.
