Abstract
Intervertebral endoprosthesis discs suitable for surgical implantation between two vertebrae having and methods thereof. The prosthetic disc may have an endoprosthesis body including an anterior region and a posterior region designed to be positioned between a first vertebra and a second vertebra with a first and second movable insert positioned rotatably in anterior cavities and is rotatable to adjust the fasteners.
Claims18
An vertebral prosthesis for surgical implantation across at least two vertebrae comprising:
- a first attachment fixture and a second attachment fixture each attachment fixture comprising an anterior region and a posterior region designed to be positioned on a surface of a vertebra, at least a first anterior cavity and a second anterior cavity positioned in the anterior region,
- a first movable insert having a first fastener aperture and positioned rotatably in the first anterior cavity, wherein the first movable insert is rotatable in the first anterior cavity, and
- a second movable insert having a second fastener aperture and positioned rotatably in the second anterior cavity, wherein the second movable insert is rotatable in the second anterior cavity independent of the first movable insert,
- wherein a first insertion angle of a first fastener extending through the first fastener aperture may be adjusted by rotating the first movable insert and a second insertion angle of a second fastener extending through the second fastener aperture may be adjusted by rotating the second movable insert;
- and
- a stabilization body attached to the first and the second attachment fixtures to extend from the first vertebra to the second vertebra.
An vertebral prosthesis for surgical implantation across at least two vertebrae comprising:
- a first attachment fixture and a second attachment fixture each attachment fixture comprising an anterior region and a posterior region designed to be positioned on a surface of a vertebra, at least a first anterior cavity and a second anterior cavity positioned in the anterior region,
- a first movable insert having a first fastener aperture and positioned rotatably in the first anterior cavity, wherein the first movable insert is rotatable in the first anterior cavity, and
- a second movable insert having a second fastener aperture and positioned rotatably in the second anterior cavity, wherein the second movable insert is rotatable in the second anterior cavity independent of the first movable insert;
- and
- a stabilization body connecting the first attachment fixture to the second attachment fixture.
An vertebral prosthesis for surgical implantation across at least two vertebrae comprising:
- a first attachment fixture and a second attachment fixture each attachment fixture comprising an anterior region and a posterior region designed to be positioned on a surface of a vertebra, and at least one anterior cavity positioned in the anterior region,
- at least one movable insert having a fastener aperture and positioned rotatably in the anterior cavity, wherein the movable insert is rotatable in the anterior cavity;
- and
- a stabilization body connecting the first attachment fixture to the second attachment fixture.
