Ledit dispositif de positionnement destiné à la mise en place d'éléments de fixation (28, 28a) pour la pose d'un élément de consolidation (15) dans des os (11) d'une partie corporelle (115), comporte une partie de base (102) cupuliforme pourvue d'une douille de guidage fixe (104) et d'une douille de guidage (108) de préférence mobile pouvant être installée à différentes positions sur une piste de guidage (106) inclinée. Le déplacement sur la piste de guidage (106) inclinée permet de positionner les éléments de fixation (28, 28a) indépendamment de prescriptions fixes et permet à ces éléments d'être saisis par un dispositif d'accouplement (25) de l'élément de consolidation (15) comportant des spirales ou des fentes inclinées. Dans un autre mode de réalisation, la partie de base (102) est appliquée sur la zone arrière (16) de l'élément de consolidation (15), est mobile avec ledit élément de consolidation le long dudit élément de consolidation par rapport à l'os, et comporte un bras (125) s'étendant vers la zone avant (24) à une certaine distance le long de l'élément de consolidation (15), bras sur lequel est ménagé la piste de guidage (106). Un élément de fixation (28) peut être enfoncé et vissé à travers une douille de guidage (108) guidée dans la partie avant de la piste de guidage, devant l'extrémité avant de l'élément de consolidation. Lors de l'avance de l'élément de consolidation (15) jusqu'à l'élément de fixation, la douille de guidage (108) coulisse dans la piste de guidage (106) jusqu'à l'extrémité de cette dernière et positionne le dispositif de positionnement pour la pose d'autres éléments de fixation (28, 28a).
