Abstract

An implant for osteosynthesis, for example a bone nail, has an implant body which has at least one bore with a threaded portion and a bone screw which engages the thread when it is threaded into a bone for the fixation of the implant body. The threaded bore has an annular groove the diameter of which is larger than the thread outer diameter, and which receives a ring of a deformable material with an inner diameter which is smaller than the outer diameter of the thread of the bone screw so that the ring extends partially into the bore.
