METHOD FOR FIXATION OF BONE FRAGMENTS AT BONE FRACTURES

摘要

The present invention relates to a device for fixation of bone fragments at bone fractures. The device comprises at least two fixation means (5, 6) and a securing plate (4). With the object of preventing or counteracting re-dislocation, the respective fixation means (5, 6) each have a first fixing portion (19) for fixing the fixation gleans in an inner bone fragment (3), a second fixing portion (21) for locking the fixation means to the securing plate (4) which is disposed on the outside of an outer bone fragment (2) and allows 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 and runs through the outer bone fragment, along which middle portion the outer bone fragment can slide inwards towards the inner bone fragment in which the fixation means is fixed.

主权项

1. A method for fixation of inner and outer bone fragments at bone fractures against rotational forces, comprising:
engaging an outer surface of the outer bone fragment with a securing plate; inserting at least two fixation means through the securing plate; fixing first fixing portions of the at least two fixation means to the inner bone fragment; fixing second fixing portions of the at least two fixation means to the securing plate; inserting a middle portion situated between the first and second fixing portions through the outer one fragment; and permitting sliding movement of the outer bone fragment along the middle portions relative to the securing plate towards the inner bone fragment and away from the securing plate during compression of the outer bone fragment and the inner bone fragment when the second fixing portions are fixed to the securing plate.
