Abstract
An interbody fusion device for fusion of vertebrae, and methods thereof. The device includes a first piece having upper and lower surfaces configured to engage the endplates of two opposing vertebrae, and a second piece that is adapted to either be inserted into the first piece or to be used independently of the first piece. The interbody fusion device can include a surface treatment, such as a porous surface treatment, to promote fusion between the device and a vertebra. The interbody fusion device may also include one or more depressions. The one or more depressions may be used in combination with a material to promote fusion between the device and a vertebra.
Claims20
An interbody fusion device for fusion of vertebrae, comprising:
- a body comprising an upper surface and a lower surface, wherein the upper and lower surfaces are adapted to contact endplates of two opposing vertebrae;
- an opening formed through the body that breaks a plane of the upper and lower surfaces;
- and
- a depression formed into at least one of the upper and lower surfaces of the body, wherein the depression is adapted to receive a component to secure the component to the body.
A method of fusing vertebrae, comprising:
- removing at least a portion of a disc between first and second vertebrae, providing an interbody fusion device comprising:
- a body comprising an upper surface and a lower surface, wherein the upper and lower surfaces are adapted to contact endplates of two opposing vertebrae;
- an opening formed through the body that breaks a plane of the upper and lower surfaces;
- and
- a depression formed into at least one of the upper and lower surfaces of the body, wherein the depression is adapted to receive a component to secure the component to the body;
- inserting the first piece between the vertebrae,
- packing the second piece with material to facilitate fusion of the first and second vertebrae, and
- inserting the second piece fully into the first piece to mate the first and second pieces.
