The invention relates to an external fixer (1) for osteosynthesis, wherein a frame (2), which is provided with at least one bar (3a, 3b), absorbs the mechanical strain and can be joined to the bone by connecting means, wherein the connecting means are joined to the frame by means of clamping jaws (4). A module (5a), which can be placed on the frame, is also provided and is used to cause a relative movement of two bone fragments towards each other. The module comprises at least two components (6a,7a). The first component (6a) can be connected to the frame and the second component (7a) can be connected to at least one clamping jaw of a connecting means which is joined to a first bone fragment. The module also comprises a means (8a) enabling the second component to move in relation to the first component, such that the bone fragment, which is connected to the second component by means of the clamping jaw can be moved as a result of said relative movement.
L'invention concerne un élément de fixation externe (1) pour ostéosynthèse, comportant un cadre (2) doté d'au moins une barre (3a, 3b) pour recevoir les sollicitations mécaniques, ce cadre étant relié à l'os par des éléments de liaison raccordés à l'os par des mâchoires de serrage (4). L'invention est caractérisée en ce qu'un module (5a) placé sur le cadre permet de déplacer deux fragments osseux dans un mouvement relatif l'un par rapport à l'autre. Ce module comprend au moins deux éléments (6a,7a) dont un (6a) est relié au cadre et l'autre (7a) est relié à au moins une mâchoire de serrage d'un élément de liaison raccordé à un fragment osseux. Le module est en outre pourvu d'un dispositif (8a) qui permet de déplacer le deuxième élément par rapport au premier, ce mouvement relatif rendant mobile le fragment osseux relié au deuxième élément par la mâchoire de serrage.
