A spinal implant includes a hollow body having a pair of lateral braches extending from a leading end to a trailing end of the hollow body. The branches have opposing concave, non-threaded inner surfaces defining an internal space of the hollow body and outer surfaces defining an outer dimension of the hollow body. The hollow body has upper and lower faces extending between leading and trailing ends thereof. At least one of the lateral branches has a first opening extending between the outer and inner surfaces thereof, and a second opening located outside the internal space of the hollow body and extending between the upper and lower faces, the first and second openings being in communication with one another. The implant also includes an anchoring member insertible between the lateral branches and into the internal space of the hollow body, whereby the concave inner surfaces of the lateral branches substantially conform to the outer diameter of the anchoring member.
