Abstract

In an orthopaedic fixing system comprising at least one implant part which has at least one through-opening, and comprising fixing elements which are inserted into the through-openings, the through-openings having widened portions which receive a head-shaped thickening of the fixing elements, in order to fix the fixing elements in the implant part in an axial direction without however impairing their ability to rotate, it is proposed that the head-shaped thickenings of the fixing elements are compressible, that the widened portions have an outside diameter which is slightly smaller than the non-resiliently-compressed head-shaped thickening, and that the widened portions have undercuts, into which the head-shaped thickening after insertion into the widened portion engages resiliently.
