  • Patent number: 7503934
    Abstract: A prosthetic device for anterior-oblique insertion into an intervertebral space is provided. The prosthetic device includes a first component having a first flange for engaging a first vertebra from an anterior-oblique approach, the first flange being angled relative to the longitudinal and transverse axes of the first component, and a second component having a second flange for engaging a second vertebra from an anterior-oblique approach, the second flange being angled relative to the longitudinal and transverse axes of the second component, and wherein the first and second components cooperate to permit articulating motion between the first and second components.

  • Publication number: 20050043802
    Abstract: 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.

  • Publication number: 20040225365
    Abstract: A prosthetic device for transforaminal insertion into an intervertebral space is provided. The prosthetic device includes a first component having a first curved flange for engaging a first vertebra from a transforaminal approach, the first component having a first articular surface, and a second component having a second curved flange for engaging a second vertebra from a transforaminal approach, 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.

  • Publication number: 20040220670
    Abstract: A prosthetic device for insertion into a spondylosed intervertebral space is provided. The prosthetic device includes a first component having a first flange for longitudinally engaging a first vertebra during longitudinal insertion therein, and a second component having a second flange for longitudinally engaging a second vertebra during longitudinal insertion therein. One of the first and second components comprises a projection and the other of the first and second components comprises a recess, the projection and recess being adapted to engage one another. One of the projection and the recess are offset relative to the other of the projection and the recess to accommodate the spondylosed relationship between the first and second vertebrae.

  • Publication number: 20040220668
    Abstract: A method for correcting spondylolisthesis from the lateral approach is provided in which a pair of insertion members are inserted laterally into upper and lower vertebrae, a connecting member is affixed to the insertion members, and a rotating force is applied to the connecting member to encourage the upper and lower vertebrae into a desired position relative to one another.
