Spinal implant

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.
