Abstract: The osteosynthesis method in accordance with the invention renders it possible to heal bone fractures of any nature, even relatively complex ones, without plaster, without pain, without external elements and within very short periods.This method consists in drilling a longitudinal passage 5 into the fractured bone from one of its extremities, in drilling a transverse hole 10 through each piece of bone, in inserting a peg 11, 12 in each transverse hole, in exerting on these pegs via a drawbar comprising a mandrel 17 in this instance whereof the screw-threaded extremity 18 is screwed into an internal screw thread of the peg 12 and whereof a shoulder 19 bears on a peg 13, a longitudinal force placing in intimate contact and exposing to a particular degree of compression the two surfaces of the break and in thus maintaining this compressive force until healing has occurred, then after this healing action, in removing the different parts in reverse order to that of their insertion.
