Abstract
A bone implant comprises a core 10 having an integral anchoring structure 12 at its surface. The structure 12 comprises an array of upwardly extending mutually spaced pointed claw-like teeth 14 for digging into bone to which the implant is to be attached, and a network of pores 16 underlying the array and communicating with the exterior of the surface via openings 18 between the teeth, the pores allowing for the circulation of nutrients to promote bone growth.
