ABSTRACT:
An external fixator includes two elements (20) of at least one pin (21, 22), each element maintaining a bone fragment (11; 12), and a telescopic piece (50 comprising an internal bar (41) and an external bar (42), each pin element being connected to either the internal or the external bar. One of the bars includes first guiding means for cooperation with corresponding second guiding means being at least indirectly dependent on the other bar, the first and second guiding means being separated from each other by roller sliding means intended to reduce the friction during the relative movement of the bars.
