Abstract

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 with curved exterior surfaces and having concave, non-threaded interior surfaces for defining an at least partially cylindrical internal space between the lateral walls. The spinal implant also includes an anchoring member having bone anchoring projections including a screw thread on an exterior surface thereof, wherein at least one of the lateral walls adjacent the proximal end of the hollow body includes a reentrant thread adapted to cooperate with the screw thread of the anchoring member when the anchoring element is rotated for enabling the anchoring member to be screwed into the internal space of the hollow body.
