Patent ID: 8231675

Claim:
A modular intervertebral implant kit for constructing an intervertebral implant comprising: a plurality of upper endcaps, each of the upper endcaps comprising a lower surface having at least a portion that is substantially flat, and an upper surface configured to contact a vertebral endplate, wherein at least one of the upper endcaps has a different shape or size than at least one other upper endcap and the upper surface of each upper endcap is a different shape than the lower surface of the upper endcap, and at least one of the upper endcaps comprises a convexly curved upper surface; a plurality of lower endcaps, each of the lower endcaps comprising an upper surface having at least a portion that is substantially flat, and a lower surface configured to contact a vertebral endplate, wherein at least one of the lower endcaps has a different shape or size than at least one other lower endcap and the lower surface of each lower endcap is a different shape than the upper surface of the lower endcap; a body configured to be disposed between the upper endcaps and lower endcaps, the body having a substantially flat upper surface configured to engage the substantially flat lower surface portion of the upper endcaps, and the body having a substantially flat lower surface configured to engage the substantially flat upper surface portion of the lower endcaps, wherein assembling at least one body between one upper endcap and one lower endcap forms an implant sized and configured for insertion between vertebral endplates.
