ABSTRACT:
A spinal implant for use in distracting and maintaining spinal disc height while promoting fusion of adjacent vertebrae of a spinal column includes first and second side surfaces extending substantially parallel to each other. Upper and lower surfaces for engaging the adjacent vertebrae extend between the first and second side surfaces and extend from a first end portion to a second end portion of the spinal implant. The spinal implant includes recesses located in the first and second side surfaces for receiving an instrument to rotate the spinal implant. A method of fusing together the adjacent vertebrae using the spinal implant includes removing at least a portion of the spinal disc between the adjacent vertebrae. The spinal implant is inserted between the adjacent vertebrae with the first and second parallel side surfaces facing the adjacent vertebrae. The spinal implant is rotated into a position in which the parallel side surfaces extend from one of the adjacent vertebrae to the other adjacent vertebrae and the upper and lower surfaces engage the adjacent vertebrae.
