A bone implant comprising a body (2) having in its outer region an open-celled porous lattice structure (3) formed from a plurality of regularly spaced unit cells (4), said unit cell (4) is designed as an assembled structure and each has an interior space (40) and a plurality of interconnected bars (41, 42, 43, 44). The porous lattice structure (3) is provided with a bone growth promoting coating (5) comprising calcium phosphate, the calcium phosphate coating (5) having a proportion of hydroxyapatite of up to 1% by weight. to form a porous inner coating that reaches deep into the porous lattice structure (3). In this way, the present invention creates a special variant of the coating, thereby departing from the conventional prevailing general idea of a coating that is relatively easy to apply and adheres well to the surface of the implant. can be done. |
