A spinal implant comprising a hollow body having a leading end, a trailing end and a pair of lateral walls extending from the leading end to the trailing end, the lateral walls including concave, non-threaded inner surfaces defining an internal space of the hollow body. The implant includes an anchoring member insertible between the lateral walls and into the internal space of the hollow body, the anchoring member having bone anchoring projections defining an outer diameter of the anchoring member. When the anchoring member is inserted into the internal space of the hollow body, the concave inner surfaces of the lateral walls substantially conform to the outer diameter of the anchoring member.
