Abstract: A device for fixation of inner and outer bone fragments comprises at least three fixation means (5), at least one tilting preventing means (6) and a securing plate (7). The fixation means (5) are configured to allow, during secondary compression of the inner and outer bone fragments (2, 3), a sliding movement of the fixation means and said outer bone fragment relative to one another and thereby an interruption of an engagement of the securing plate (7) with the outer bone fragment (3) without affecting the angular position of the fixation means relative to the securing plate and relative to one another. The tilting preventing means (6) is configured to allow, during said secondary compression, a sliding movement of the at least one tilting preventing means and said outer bone fragment (3) relative to one another and thereby an interruption of the engagement of the securing plate (7) with the outer bone fragment.
