Abstract: The present invention relates to a bone implant comprising a porous body comprising particles of bioactive glass having a particle size of at least 500 ?m, wherein the composition of the bioactive glass is 45-59 weight-% of SiO2, 18-25 weight-% of Na2O, 17-25 weight-% of CaO and 0.1-6 weight-% of P2O5, and a film having a thickness of 10 ?m-200 ?m, made of a biocompatible polymer and arranged at least partially around the body.

Abstract: The present invention relates to a bioactive glass having the composition of SiO2 44-65 wt-% of the final total weight, Na2O 5-26 wt-% of the final total weight, CaO 10-25 wt-% of the final total weight, K2O 0-1 5 wt-% of the final total weight, MgO 0-6 wt-% of the final total weight, B2O3 0-4 wt-% of the final total weight, and P2O5 0-7 wt-% of the final total weight, for use in the long- and short-term prevention and/or treatment of conditions relating to or caused by bone infections, provided that the total amount of Na2O and K2O is 10-30 wt-% of the final total weight, and that any source of oxygen capable of releasing oxygen in the form of molecular oxygen or reactive oxygen species, is absent.
