Publication number: 20070179616Abstract: A prosthetic device for posterior placement in an intervertebral space defined between an upper vertebrae and a lower vertebrae may include an upper articular portion configured to be at least partially disposed in the intervertebral space and a lower articular portion configured to be at least partially disposed in the intervertebral space below the upper articular portion, the upper and lower articular portions being configured to provide articulating motion to the upper and lower vertebrae. The upper and lower articular portions each may include a posterior section configured to be disposed in a location posterior of the intervertebral space. The posterior section of one of the upper and lower articular portions may include a post, and the posterior section of the other of the upper and lower articular portions may include a receiving portion configured to interact with the post during articulation.Type: ApplicationFiled: January 30, 2006Publication date: August 2, 2007Applicant: SDGI Holdings, Inc.Inventors: Danny Braddock, Marc Peterman, Scott Hodges, Kidong Yu, Steven Humphreys

Publication number: 20050154467Abstract: An artificial spinal joint for creating at least a portion of a coupling between a superior vertebra and an inferior vertebra comprises an inferior arthroplasty half. The inferior arthroplasty half comprises an inferior articulating component for placement in an intervertebral disc space between the superior and inferior vertebrae, a first posterior arm, and a first bridge component coupled between the inferior articulating component and the first posterior arm. The artificial spinal joint further includes a superior arthroplasty half. The superior arthroplasty half comprises a superior articulating component for placement in an intervertebral disc space between the superior and inferior vertebrae, a second posterior am, and a second bridge component coupled between the superior articulating component and the second posterior arm. The first posterior arm and the second posterior arm cross an anterior-posterior axis defined centrally through and extending from the intervertebral disc space.Type: ApplicationFiled: January 7, 2005Publication date: July 14, 2005Applicant: SDGI Holdings, Inc.Inventors: Marc Peterman, Steven Humphreys, Scott Hodges
