Patent ID: 7063725

Claim:
An implant for the spinal column, comprising: a body positionable in a spinal disc space, said body including a leading end portion and an opposite proximal end, an upper surface orientable toward an endplate of an upper vertevra and a lower surface orientable toward an endplate of a lower vertebra, said body having a height between said upper and lower surfaces corresponding to a desired disc space height between the upper vertebra endplate and the lower vertebra endplate, wherein said leading end portion is adapted for insertion into the disc space in a collapsed condition to restore the collapsed disc space to the desired disc space height as the body is inserted in the collapsed disc space, wherein said body includes: a first lateral section and second lateral section attachable to said first lateral section, wherein one of said first and second lateral sections includes a receptacle extending laterally therethrough for receiving a coupling pin: a first lateral surface on said first lateral section extending between said upper surface and said lower surface; a second lateral surface on said second lateral section opposite said first lateral surface extending between said upper surface and said lower surface; a first notch in said first lateral surface opening at said proximal end; a second notch in said second lateral surface opening at said proximal end; and further comprising a coupling member having first and second portions positionable in respective ones of said first and second notches to secure said first and second lateral sections to one another, wherein said first lateral section includes a first medial surface and said second lateral section includes a second medial surface oriented toward said first medial surface, said first and second medial surfaces configured to interdigitate when positioned against one another and said each of said first and second medial surfaces includes a plurality of ridges extending between said upper and lower surfaces.
