Patent number: 8652212Abstract: 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 29, 2009Date of Patent: February 18, 2014Assignee: Zimmer, Inc.Inventors: Kirt L. Case, Oludele O. Popoola, Robby Kissling, Brion R. Mimnaugh, Archie W. Newsome, Clarence M. Panchison, Dirk L. Pletcher, Randy L. Schlemmer, Zhibin Fang, Juan Vivanco, Alicia Rufner

Patent number: 8308811Abstract: An acetabular implant for hip replacement surgery includes a shell component and first and second alternative bearing components interchangeably engageable with the shell component to provide a choice in bearing components. The shell component has a shell component engagement mechanism suitable for engaging the first alternative bearing component. A conversion ring is also engageable with the shell component, so that a shell component/conversion ring assembly provides a second shell component engagement mechanism suitable for engagement with the second alternative bearing component.Type: GrantFiled: March 31, 2010Date of Patent: November 13, 2012Assignee: Zimmer, Inc.Inventors: Archie W. Newsome, Randy L. Schlemmer, Erin M. Johnson, Richard A. Berger

Patent number: 7985259Abstract: An acetabular implant for hip replacement surgery includes a shell component and first and second alternative bearing components interchangeably engageable with the shell component to provide a choice in bearing materials. The shell component has an engagement mechanism suitable for locking engagement with the first alternative shell component. A conversion ring is lockingly engageable with the shell component to adapt the shell component to provide an engagement mechanism suitable for locking engagement with the second alternative shell component.Type: GrantFiled: July 16, 2009Date of Patent: July 26, 2011Assignee: Zimmer Technology, Inc.Inventors: Richard A. Berger, Erin M. Johnson, Archie W. Newsome, Randy L. Schlemmer

Patent number: 7828805Abstract: A hip stem centralizer datum guide and method are provided for positioning a proximal portion of a hip stem component within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.Type: GrantFiled: February 2, 2006Date of Patent: November 9, 2010Assignee: Zimmer Technology, Inc.Inventors: Stephen H. Hoag, James L. Crumley, Scott J Steffensmeier, Erin M. Johnson, Kevin S. Cook, Archie W. Newsome, Bobby Chan

Publication number: 20090048603Abstract: A hip stem centralizer datum guide (40, 100, 200, 300) and method are provided for positioning a proximal portion of a hip stem component (44) within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum (70, 72, 74, 76, 120, 220, 302) that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.Type: ApplicationFiled: February 1, 2007Publication date: February 19, 2009Applicant: ZIMMER TECHNOLOGY, INC.Inventors: Stephen H.
