Abstract
The invention relates to an implantable orthopaedic device comprising a load-bearing element, such as a bone plate, for fixing elements, such as bone screws, that can be oriented polyaxially. The load-bearing element is equipped with at least one opening for the passage of the fixing elements. A two part insert is provided in the opening, the insert having an external form that complements the internal form of the receiving opening and permits the polyaxial rotation of the insert in the opening. The insert is equipped with a central bore for receiving the body of the fixing element. The first insert element part has a central inner hollow chamber, into which the second insert element part can be introduced. The first insert element is flexible or has at least one slit, in such a way that when the two insert elements are displaced axially in relation to one another, the first insert element in the plate can be expanded at least partially in order to block the position and alignment of the fixing element in the device in a polyaxial manner.
