Abstract
An interlocking intervertebral disc prosthesis is provided. The prosthesis can include a left prosthetic body and a right prosthetic body that interlock with one another. A kit for replacing an intervertebral disc with an interlocking intervertebral disc prosthesis is also provided. A method for surgically implanting an interlocking intervertebral disc prosthesis is also provided.
Claims32
An interlocking intervertebral disc prosthesis, comprising:
- a left prosthetic body comprising at least one rigid endplate;
- a right prosthetic body comprising at least one rigid endplate, each of the prosthetic bodies having a lateral surface, a medial surface, a posterior surface, an anterior surface, a superior surface, and an inferior surface;
- means for interlocking the left prosthetic body to the right prosthetic body, the interlocking means located on the medial surfaces of the prosthetic bodies;
- and
- means for accepting an insertion tool located on a surface of the left prosthetic body and a surface of the right prosthetic body.
An interlocking intervertebral disc prosthesis, comprising:
- a left prosthetic body comprising at least one rigid endplate;
- a right prosthetic body comprising at least one rigid endplate, each of the prosthetic bodies having a lateral surface, a medial surface, a posterior surface, an anterior surface, a superior surface, and an inferior surface;
- at least one male fastener located on the medial surface of one of the left prosthetic body and the right prosthetic body and at least one female fastener located on the medial surface of the other of the left prosthetic body and the right prosthetic body;
- wherein the male and female fasteners are configured and positioned such that the left prosthetic body and the right prosthetic body interlock in an applied position;
- and
- one or more openings for accepting an insertion tool located on a surface of the left prosthetic body and a surface of the right prosthetic body.
An interlocking intervertebral disc prosthesis, comprising:
- a left prosthetic body comprising at least one rigid endplate;
- a right prosthetic body comprising at least one rigid endplate, wherein each of the left and right prosthetic bodies has a medial surface, a lateral surface, a posterior surface, an anterior surface, a superior surface, and an inferior surface;
- at least one additional prosthetic body comprising at least one endplate, the at least one additional prosthetic body having a left surface, a right surface, a posterior surface, an anterior surface, a superior surface, and an inferior surface;
- means for interlocking the at least one additional prosthetic body to the left and right prosthetic bodies or any additional prosthetic bodies positionable between the left and right prosthetic bodies, the interlocking means located on the medial surfaces of the left and right prosthetic bodies and the left and right surface of the at least one additional prosthetic body;
- and
- means for accepting an insertion tool located on a surface of each of the prosthetic bodies.
A method for surgically implanting an interlocking intervertebral disc prosthesis in an intervertebral space of a patient, the method comprising:
- removing the natural intervertebral disc from the intervertebral space;
- inserting a multi-piece prosthetic into the intervertebral space, the multi-piece prosthetic comprising a left prosthetic body comprising at least one rigid endplate and a right prosthetic body comprising at least one rigid endplate;
- and
- interlocking the left prosthetic body and the right prosthetic body.
A method for surgically implanting an interlocking intervertebral disc prosthesis in an intervertebral space of a patient, the method comprising:
- removing the intervertebral disc on the right lateral side and the left lateral side of the intervertebral space;
- impacting a left and a right intervertebral disc prosthetic bodies individually in the intervertebral space, each of the prosthetic bodies having a lateral side;
- attaching a pair of compression forceps to the lateral sides of the right and left intervertebral disc prosthetic bodies;
- and
- squeezing the compression forceps to attach the left and right intervertebral disc prosthetic bodies to one another.
A method for surgically implanting an interlocking intervertebral disc prosthesis in an intervertebral space of a patient, the method comprising:
- removing the intervertebral disc on the right lateral side and the left lateral side of the intervertebral space;
- impacting a left and a right intervertebral disc prosthetic bodies individually in the intervertebral space using a left and right insertion tool, each of the prosthetic bodies having a lateral side;
- attaching a pair of compression forceps to the lateral sides of the right and left insertion tools;
- and
- squeezing the compression forceps to attach the left and right intervertebral disc prosthetic bodies to one another.
An interlocking intervertebral disc prosthesis, comprising:
- a left prosthetic body comprising at least one rigid endplate;
- a right prosthetic body comprising at least one rigid endplate, each of the prosthetic bodies having a lateral surface, a medial surface, a posterior surface, an anterior surface, a superior surface, and an inferior surface;
- and
- means for interlocking the left prosthetic body to the right prosthetic body and accepting an insertion tool, the interlocking and accepting means located on the medial surfaces of the prosthetic bodies.
