Patent number: 7708777Abstract: A modular disc prosthesis system is provided that allows a disc prosthesis to be constructed, either pre- or intra-operatively, to have a desired degree of freedom or constraint when positioned between endplates of adjacent vertebrae. In particular, the components can be assembled to form a disc prosthesis having a center of rotation that is constrained or fixed such that, when the disc prosthesis is implanted between endplates of adjacent vertebrae, the adjacent vertebrae have one degree of freedom and move about a fixed center of rotation. Alternatively, one or more of the same components and one or more additional components of the system can be used to construct a disc prosthesis having a center of rotation that is unconstrained or that floats such that, when the disc prosthesis is implanted between the endplates of adjacent vertebrae, the adjacent vertebrae have multiple degrees of freedom and can move about a floating or moving center of rotation, i.e., a center of rotation that is not fixed.Type: GrantFiled: February 3, 2006Date of Patent: May 4, 2010Assignee: DePuy Spine, Inc.Inventors: Michael J. O'Neil, Jeffrey Karl Sutton, Andrew Dooris

Publication number: 20070100456Abstract: An intervertebral disc prosthesis comprises a superior endplate, an inferior endplate, and an intermediate core positioned between the endplates. The core comprises a central disc portion and a radial flange. The central disc portion of the core is defined by a superior bearing surface and inferior bearing surface. The radial flange of the core includes a first portion that extends radially outward from the central disc portion of the core. The radial flange also includes a second portion that extends axially from the first portion of the flange. The second portion of the flange extends a substantially greater distance toward the inferior endplate than toward the superior endplate. In one embodiment, the second portion of the flange extends completely to the inferior endplate and engages the inferior endplate when the inferior endplate is in a neutral position relative to the core.Type: ApplicationFiled: May 12, 2006Publication date: May 3, 2007Applicant: DePuy Spine, Inc.Inventors: Andrew Dooris, Christopher Rogers, Matthew Parsons
