Abstract
A spinal implant may be used to stabilize a portion of a spine. The implant may promote bone growth between adjacent vertebrae that fuses the vertebrae together. An implant may include an opening through a height of a body of the implant. The body of the implant may include curved sides. A top and/or a bottom of the implant may include protrusions that contact and/or engage vertebral surfaces to prevent backout of the implant from the disc space. A variety of instruments may be used to prepare a disc space and insert an implant. The instruments may include, but are not limited to, a distracter, a rasp, and one or more guides. The implant and instruments may be supplied in an instrument kit.
Claims36
A spinal implant, comprising:
- a distal end;
- a proximal end opposite the distal end;
- a top extending between the distal end and the proximal end, wherein at least a portion of the top is shaped to contact a first vertebra;
- a bottom extending between the distal end and the proximal end opposite the top, wherein at least a portion of the bottom is shaped to contact a second vertebra, wherein the second vertebra is adjacent to the first vertebra;
- an anterior side extending between said top and said bottom and having:
- a first curvature between the distal end and the proximal end of said spinal implant;
- and
- a first groove located on the first curvature near said proximal end and
- extending from and passing through said top to said bottom;
- a posterior side extending between the top and the bottom opposite said anterior side and having:
- a second curvature between said distal end and said proximal end of said spinal implant;
- and
- a second groove located on the second curvature near said proximal end and extending from and passing through said top to said bottom;
- and
- an opening extending through the spinal implant from the top to the bottom.
A spinal implant, comprising:
- a body, wherein the body comprises:
- a distal end;
- a proximal end opposite the distal end;
- a top extending between the distal end and the proximal end;
- a bottom extending between the distal end and the proximal end opposite the top;
- a curved anterior side between said top, said bottom, the distal end, and the proximal end of said body;
- a curved posterior side opposite said curved anterior side and between said top, said bottom, said distal end, and said proximal end;
- two grooves recessing into said body from and passing through said top to said bottom on said anterior side and said posterior side;
- and
- an opening extending through the body from the top to the bottom.
