Abstract:
1. A system for fixation of fractures comprising a polyethylene chassis and one or more one-piece fixation elements in the form of screws and/or pins which are adapted to be received in a bone structure, wherein each fixation element is also received in the polyethylene chassis and wherein the polyethylene chassis is made of UHMWPE (ultra high molecular weight polyethylene) which has an elasticity giving a locking effect by friction on the fixation elements in such a way that said fixation elements are frictionally engaged by said UHMWPE chassis as said fixation elements are received by said UHMWPE chassis and thereby are capable of being locked by friction regarding movement in axial, rotational and angular directions as said fixation elements are received by said UHMWPE chassis, said UHMWPE chassis being spaced from said bone structure when said fixation elements are frictionally engaged by said chassis.
