Abstract:
1. A bone fixation device comprising: a first bone implant with at least one through hole defined at least in part by a through hole wall, wherein said first bone implant comprises a hollow intramedullary nail with a longitudinal cavity, wherein said at least one through hole has two outer openings with an area A at a peripheral surface of the hollow intramedullary nail and two inner openings towards said longitudinal cavity; at least one second bone implant with a head and a shaft for insertion into said at least one through hole; and at least one closing cover for closing one of said two outer openings of said at least one through hole, wherein said closing cover is made of an elastic material and is removably attachable to said first bone implant; wherein said closing cover is dimensioned and shaped in such a way that, upon attachment to said first bone implant, the elastic material makes contact with at least a portion of the through hole wall at one of said two outer openings, and said closing cover covers at least the entire area A of one of said two outer openings and the head of said at least one second bone implant and any additional second bone implants inserted into said at least one through hole thereby preventing bacterial invasion through one of said two outer openings into said at least one through hole; and wherein the closing cover is removably fixable to the through hole wall at one of said two outer openings by a press-fit arrangement, a form-fit arrangement or an adhesive.
