摘要：
The invention relates to a pair of dynamic external attachment devices (100) for reducing fractures of bone fragments, said devices (100) being arranged on either side of a first bone portion through which a first pin (10) passes in proximal position and a second bone portion through which a second pin (11) passes in distal position, while each of the dynamic external attachment devices (100) includes a first part body (1) having a longitudinal profile with axis (X, X), comprising a proximal through-bore (5) with axis (Y, Y) engaging with the first pin (10), said first part body (1) being enclosed in a first helical spring (8), while said first spring (8) is nested in a second helical spring (12), mounted so as to interact with a second part body mounted so as to interact with said first part body (1), while the second part body is mounted so as to interact with the second pin (11).
