The present invention relates to pins for reduction and osteosynthesis of bone fractures. The pin according to the invention is characterised essentially by the fact that it comprises a threaded rod 2, a tapped nut 3 screwed onto the threaded rod 2, the nut being defined by at least two parts, a first part 4 of frustoconical shape and a second part 5 which essentially has the general shape of a hemisphere, the large base of the frustoconical part and the base of the hemispherical part being connected in such a way that the vertices 9 and 10 of the two parts are arranged on either side of the planes 11 of the two bases 7, 9. Application: osteosynthesis of fractures, in particular of the lower end of the radius. <IMAGE>
