Abstract
An implant for use in bone fixation, includes combination of the two materials: metal and plastic. The implant defines several passages with axles (3) running through the implant, which are suitable for receiving a bone fixation device, such as a bone screw. The passages are provided with a peripheral perimeter, which is made of a different material than the material of the implant surrounding the perimeter. The implant is, on the one hand, not too rigid and, on the other hand, does not present problems as regards the screw-implant interface.
