An external bone fixation system for clamping bone pins and a connecting element is provided. The system includes a jaw and an upper element for retaining bone pins therebetween, a middle element, and a lower element, with the elements being disposed about a common axis. The upper element swivels relative to the middle element, and the lower element rotates relative to the middle element. A borehole extending through the lower element permits demountable attachment of the device to the connecting element, as well as rotation thereabout. Opposing surfaces of at least two of the elements are positively engageable. The upper, middle, and lower elements are coupled by a common fastener disposed along the common axis, while the jaw and upper element are coupled by at least one fastener that is not disposed on the common axis. A single fastener can be used to arrest two or three degrees of freedom of movement.

L'invention concerne un dispositif de fixation externe de fragments d'os fracturés. Ce dispositif qui peut être fixé à un élément de liaison (1), comprend une mâchoire (35), un élément pivotant supérieur (4), un élément pivotant central (5) et un élément pivotant inférieur (6). Ces éléments pivotants (4 ; 5 ; 6) sont placés le long d'un axe (38). Au moins deux vis osseuses (3) ou broches peuvent être serrées entre la mâchoire (35) et une surface de serrage (47) située sur l'élément pivotant supérieur (4). L'élément pivotant supérieur (4) peut tourner par rapport à l'élément pivotant central (5) autour d'un axe de rotation (60) qui est perpendiculaire à l'axe (38) et peut être calé contre la première face frontale (61) de l'élément pivotant central (5) qui est perpendiculaire à l'axe (38). L'élément pivotant inférieur (6) peut tourner par rapport à l'élément pivotant central (5) autour de l'axe (38) et peut être calé contre sa deuxième face frontale (62).
