Abstract
Official abstract text for this publication.
A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs B 1 and B 2 with respective radii R 1 and R 2 and respective centers Z 1 and Z 2 located at a distance X≧0 extending transversely to the resilient element whereby the ratio R 1 :R 2 is in the range between 0.5 and 2.0.
First claim
Opening claim text (preview).
What is claimed is: 1. A device for bone fixation defining at least one through hole extending therethrough, the through hole including first and second through apertures separated from one another by a first resilient element deformable radially outward from the first aperture to expand the first aperture and contract the second aperture, the second aperture being sized and shaped to receive therein a bone fixation element, the second through aperture being smaller in size than the first through aperture, a periphery of the first through aperture comprising at least two substantially circular arcs B 1 and B 2 with respective radii R 1 and R 2 and respective centres Z 1 and Z 2 located at a distance X>0 extending transversely to the resilient element whereby the ratio R 1 :R 2 is in the range between 0.5 and 2.0, wherein the through hole further comprises a third through aperture which does not overlap the first and second apertures, the third through aperture being separated from the first through aperture by a second resilient element deformable radially outward from the first aperture to expand the first aperture and contract the third aperture, the third aperture being sized and shaped to receive therein a bone fixation element.
