Publication number: 20230200857Abstract: An implantable, modular spine stabilization system that allows for multi-level treatment of the spine by providing either rigid fixation or dynamic stabilization at different levels to be treated is provided. This modular spine stabilization system may be configured to span multiple spine levels, and have a curvature that closely matches the curvature of the spine over those multiple levels to be treated. Further, the modular spine stabilization system allows adjustment of the curvature of the overall system such that the system may be adapted for a patient for a customized fit. Instruments are also provided for the assembly and/or implantation of the modular spine stabilization system. The associated instruments may include instruments for adjusting the curvature of the system to the patient, and for implanting the curved system into the patient. The instruments may be configured for implantation of the system in a minimally invasive surgery.Type: ApplicationFiled: February 20, 2023Publication date: June 29, 2023Inventors: Stephan Eckhof, Markus Salvermoser, Rudolph Bertagnoli, William R.

Publication number: 20130079783Abstract: An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The system also includes a cutting tool which is used to form a cutout in an adjacent vertebra.Type: ApplicationFiled: November 16, 2012Publication date: March 28, 2013Inventors: Rudolph Bertagnoli, Daniel Murrey, John P.

Patent number: 8394142Abstract: A method and apparatus for customizing an intervertebral implant includes the initial step of obtaining a 3D anatomy of a series of vertebrae including an abnormal vertebra in a computer. The 3D anatomy of the series is then repositioned in the computer to eliminate the deformity caused by the abnormal vertebra. It is next determined whether a superior or inferior surface of the abnormal vertebra is an abnormal surface which causes the deformity, whereby an approximate gap between the abnormal surface and a desired normal surface is determined. Using that gap determination, a custom implant is constructed to engage the abnormal surface and fill the determined gap. Thus, when the implant is implanted between the abnormal surface and an adjacent surface of an adjacent vertebrae, the deformity is substantially compensated for. The implant may have articulation between the endplates to allow relative movement therebetween.Type: GrantFiled: June 13, 2005Date of Patent: March 12, 2013Assignee: Synthes USA, LLCInventors: Rudolph Bertagnoli, Thierry Marnay, Christophe Geisert, Eduard Kufeld, Barbara Schweizer

Patent number: 8337500Abstract: An instrument system, associated milling or drilling guide and method include use of a trial implant of a size corresponding to an actual implant for the intervertebral space, with a milling guide mounted on the trial implant. The milling guide includes a longitudinal guide chamber which is tapered from a forward end to a rearward end. The system also includes a cutting tool which is received in the guide chamber in order to form a cutout in an adjacent vertebra. This cutting tool includes a bearing member which pivotally engages the rearward end to form a pivot axis for the cutting tool in the tapered guide chamber. Either the milling guide can be inverted to form the cutout in the other vertebra; or the milling guide can be provided with two guide chambers, to be used with one cutting tool moved between them or two respective cutting tools.Type: GrantFiled: July 30, 2007Date of Patent: December 25, 2012Assignee: Synthes USA, LLCInventors: Rudolph Bertagnoli, Daniel Murrey, John P.

Publication number: 20080312693Abstract: A functionally dynamic stabilization unit and system for treatment of spinal instability are provided. Each unit, and collectively, the system, is configured to control flexion, extension and translation of the affected unstable vertebral area, thereby stabilizing the vertebral segments by restoring normal function. This is achieved by providing a unit and system that allow for lateral bending, axial compression, rotation, anterior segmental height adjustment, and posterior segmental height adjustment. The unit and system provide sufficient segmental stiffness, while also limiting, or controlling, the range of motion (i.e., sufficient stiffness in the neutral or active zone, while limiting or preventing motion outside of the active zone) to stabilize the vertebral segments. In use, the system mimics the natural movement of the normal spine. Furthermore, the system includes a rigid, fusion-promoting coupler configured for use in an adjacent level, or as a substitute for the functionally dynamic unit.Type: ApplicationFiled: December 7, 2007Publication date: December 18, 2008Inventors: Frank T. Trautwein, Bernhard Holtkamp, Rudolph Bertagnoli, Markus Salvermoser, Gary L. Lowery, Guntmar H. Eisen

Publication number: 20050043802Abstract: A prosthetic device for lateral insertion into an intervertebral space is provided. The prosthetic device includes a first component having a first laterally-extending flange for engaging a first vertebra from a lateral approach to the first vertebra, the first component having a first articular surface. The prosthetic device further includes a second component having a second laterally-extending flange for engaging a second vertebra from a lateral approach to the second vertebra, the second component having a second articular surface for cooperating with the first articular surface to permit articulating motion between the first and second components.Type: ApplicationFiled: February 6, 2004Publication date: February 24, 2005Applicant: SDGI Holdings, Inc.Inventors: Lukas Eisermann, Tai Friesem, Jean-Charles LeHuec, Hallet Matthews, Rudolph Bertagnoli
