Abstract: The present invention relates to a medical fastening device for the fastening of grafts, wherein the medical fastening device is suitable for being inserted in a bone tunnel of a bone, and wherein said medical fastening device comprises a first fastening element and a second fastening element.

Abstract: The invention relates to a device for trapping the end of at least one fascicle (10) of soft material in a bone tunnel (1), comprising: a ferrule (100), a screw (200) and a washer (300), the ferrule comprising a proximal upper rim (140) and screwing elements (150), with a longitudinal axis (151) inclined ? degrees in relation to the longitudinal axis (101) of the ferrule, and an inner thread (152) reciprocal to the outer thread (201) of the screw, the assembly being designed such that as the screw, with the washer, screws into the inner thread (152), the outer face (301) of the washer (300) approaches the inner face (142) of the proximal upper rim (140), an upper passage being formed between the two, via which the soft material projects, which is trapped in this way.
