Abstract
Methods for forming a shaped surface, for example, a shaped end plate between adjacent vertebral bodies, and a bone removal device for use in such methods. The device includes a contour having a predetermined profile corresponding at least in part to an implant, and a cutting element following the contour and having a cutting edge having a profile corresponding to the contour profile.
Claims26
A device comprising:
- a contour having a predetermined profile corresponding at least in part to the profile of an implant;
- and
- a cutting element rotatably attached to the contour, which cutting element has a cutting edge having a profile corresponding to the contour profile.
A system for preparing a site comprising:
- an access instrument operable to provide access to the site;
- and
- a bone removal device, which bone removal device comprises a contour and a cutting element attached to the contour, which contour has a profile corresponding at least in part to the profile of an implant to be inserted at the site, and which cutting element has a cutting edge having a profile corresponding to the contour profile.
A system for preparing a site comprising:
- means for providing access to the site;
- and
- means for shaping a surface at the site to have a profile corresponding at least in part to the profile of a device to be inserted into contact with the surface.
A method of preparing a space between first and second vertebral bodies to receive an implant, the method comprising:
- attaching first and second anchoring devices to the first and second vertebral bodies, respectively;
- attaching a distraction assembly to the first and second anchoring devices, wherein a first arm of the distraction assembly is attached to the first anchoring device and a second arm of the distraction assembly is attached to the second anchoring device;
- and
- attaching a bone removal device to the first distractor arm, which bone removal device comprises a contour and a cutting element attached to the contour, which contour has a profile corresponding at least in part to the profile of the implant, and which cutting element has a cutting edge having a profile corresponding to the contour profile;
- and
- shaping a first endplate of the first vertebral body with the cutting element.
A method of preparing a site between first and second vertebral bodies to receive an implant, the method comprising:
- creating space between first and second vertebral bodies;
- and
- shaping a first endplate of the first vertebral body with a bone removal device comprising a contour and a cutting element attached to the contour, which contour has a profile corresponding at least in part to the profile of the implant, and which cutting element has a cutting edge having a profile corresponding to the contour profile.
