摘要:
A device for fixation of bone fragments at bone fractures including at least two fixation means (5, 6), a securing plate (4) and at least one securing means (23) for the fixation means. Each fixation means (5, 6) has a first fixing portion (19) for fixing the fixation means in an inner bone fragment (3), a second fixing portion (21) which serves in conjunction with the securing means (23) for locking the fixation means in a hole (9) which runs through the securing plate (4) disposed on the outside of an outer bone fragment (2) and allowing movement of the outer bone fragment relative to it, so that the fixation means are prevented from changing their angular position relative to the securing plate and relative to one another, and a middle portion (22) which is situated between the fixing portions (19, 21) and runs through the outer bone fragment (2), along which middle portion the outer bone fragment can slide inwards towards the inner bone fragment (3) in which the fixation means is fixed, and the securing means (23) has an external thread for screwing it firmly into a hole (9) in the securing plate (4).
