Résumé : The word osteosynthesis was proposed by A. Lambotte in 1904. His definition, given in 1908, is still valid today: "Osteo-synthesis is the artificial contention of the bone fragments of fractures, by special devices acting directly on bones, exposed or not, with the aim to strongly fix them in their original position". The authors review the methods of contention before the invention of osteosynthesis and later the developments of bone fixation techniques. They insist in particular on the durable innovations of various pioneers including A. Lambotte, R. Danis, R. Hoffmann and G. Küntscher. The School of Brussels has been implicated in the developments and conceptualisation of osteo-synthesis.
