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.
Claims16
A method for stabilizing vertebral bodies, said method comprising:
- providing a vertebral implant including:
- a first attachment fixture having a first anterior region and a first posterior region;
- a first insert having a first fastener aperture and disposed within a first anterior cavity of the first anterior region, wherein the first insert is rotatable in the first anterior cavity;
- a second insert having a second fastener aperture and disposed within a second anterior cavity of the first anterior region, wherein the second insert is rotatable in the second anterior cavity;
- a second attachment fixture having a second anterior region and a second posterior region;
- a third insert having a third fastener aperture and disposed within a third anterior cavity of the second anterior region, wherein the third insert is rotatable in the third anterior cavity;
- a fourth insert having a fourth fastener aperture and disposed within a fourth anterior cavity of the second anterior region, wherein the fourth insert is rotatable in the fourth anterior cavity;
- a third attachment fixture having a third anterior region and a third posterior region;
- a fifth insert having a fifth fastener aperture and disposed within a fifth anterior cavity of the third anterior region, wherein the fifth insert is rotatable in the fifth anterior cavity;
- a sixth insert having a sixth fastener aperture and disposed within a sixth anterior cavity of the third anterior region, wherein the sixth insert is rotatable in the sixth anterior cavity;
- fixating the first attachment fixture to a first vertebral body;
- fixating the second attachment fixture to a second vertebral body;
- fixating the third attachment fixture to a third vertebral body;
- coupling, via a first connecting member, the first attachment fixture to the second attachment fixture;
- and
- coupling, via a second connecting member, the second attachment fixture to the third attachment fixture
- wherein the vertebral implant has a first fastener including:
- a head sized and shaped to contact the first fastener aperture of the first insert;
- and
- a first set of proximal threads adapted to mate with complimentary threads of the first fastener aperture of the first insert, and
- wherein each of the first insert, second insert, third insert, fourth insert, fifth insert, and sixth insert are cylinders each having two bases separated by a curved outer surface extending around the two bases, and wherein each of the first fastener aperture, second fastener aperture, third fastener aperture, fourth fastener aperture, fifth fastener aperture, and sixth fastener aperture is disposed on the curved outer surface of a respective one of the first insert, second insert, third insert, fourth insert, fifth insert, and sixth insert.
