A spinal implant includes a hollow body having a distal end, a proximal end, and a pair of lateral walls extending from the distal end to the proximal end, the lateral walls having a concave-shaped cross-section and having concave, non-threaded interior surfaces for defining an at least partially cylindrical internal space between the lateral walls. The hollow body has upper and lower faces that are inclined relative to one another, whereby a distance between the upper and lower faces decreases from a first lateral side of the hollow body to a second lateral side of the hollow body opposite the first lateral side. The implant includes an anchoring member having bone anchoring projections that is inserted into the hollow body. The anchoring member is rotatable for enabling the anchoring member to be screwed into the internal space of the hollow body.
