Device for osteosynthesis |
摘要 |
A device for osteosynthesis that includes a fixation element having at least one through hole designed to receive a pivotable bushing for a bone screw. The through hole having a central axis and a cross-section extending orthogonally to the central axis defined by two incomplete semicircles connected to each other by at least two non-circular cut outs forming grooves in the fixation element. The device also includes at least one bushing insertable in the through hole. The bushing has top and bottom surfaces, a longitudinal axis, a central bore designed to receive a bone screw, and a peripheral outside face having at least two outwardly extending protrusions defining an axis of rotation of the bushing extending through the protrusions. A cross section of the bushing orthogonal to the longitudinal axis is shaped such that the bushing is pivotable about the axis of rotation defined by the protrusions.
