摘要： The device for performing osteosynthesis includes a fixation element, such as a bone plate having a bottom surface designed to bear against the bone, a top surface, and at least one through hole extending from the bottom surface to the top surface, the though hole having a central axis and configured and dimensioned to receive a multiaxially pivotal insert or bushing for a bone screw. A bushing insertable into the through hole, includes a central bore designed to receive a bone screw, the central bore having a longitudinal axis, and a peripheral outer surface designed to be in contact with the through hole. The bushing is configured and dimensioned to be radially compressible and radially expansible, and the cross section of the through hole, which is orthogonal to the central axis, is non-circular. The cross section of the bushing that is orthogonal to the longitudinal axis has a shape that corresponds substantially to the cross section of the through hole of the bone plate. When placed in the through hole, the bushing is rotationally fixed relative to its longitudinal axis, but remains pivotally adjustable within the through hole relative to the bone plate.

摘要： A bone plate system includes (a) Bone Plate having a bottom surface for contacting bone, an upper surface and at least one through hole extending from the bottom surface to the upper surface, the through hole having a central axis and a cross-section that extends orthogonally to the central axis and is one of at least partially polygonal, at least partially prismatic, and at least partially elliptical; (b) Bushing within the through hole, Bushing including a central bore designed to receive a bone fixation element, a cross-section of Bushing orthogonal to the longitudinal axis of Bushing is shaped substantially the same as the cross-section of the through hole so that Bushing is secured against rotation about its longitudinal axis; and (c) at least one Bone Fixation Element having a portion for anchoring within bone, Bone Fixation Element configured and dimensioned for insertion into the central bore of Bushing.
