Abstract: An orthopaedic attachment device (1) which can adopt at least two positions, an inoperative position and a locked position. The orthopaedic attachment device comprises two clamps (2a, 2b) mounted opposite each other through a resilient member, and held by a clamping rod along a median axis by through-holes. Each of the clamps (2a, 2b) comprises a body part that comprises a outer jaw (4b) and an inner jaw (4a), connected by a joining wall (5), and which defines an opening that is designed to accommodate a stiffening bar or a pin via an insert. The opening extends inwards from the clamp (2a, 2b) as far as the joining wall (5) towards a passage and a hinge region. In the inoperative position, the outer jaw (4b) is fixed, whereas the inner jaw (4a) is moveable inwards towards the resilient member.

Abstract: Pair of dynamic external fixation devices (100) for the reduction of fractures of bone fragments, said devices (100) being arranged on either side of a first bone portion traversed by a first pin (10) in a proximal position and a second bone portion traversed by a second pin (11) in distal position, while each of the dynamic external fixation devices (100) includes a first body (1) having a longitudinal axis profile (X, X?), having a proximal bore (5) passing through an axis (Y, Y?) in combination with the first pin (10), said first body (1) being embedded in a first coil spring (8), while said first spring (8) is nested in a second coil spring (12), mounted in conjunction with a second body mounted in conjunction on said first body (1), while the second body is mounted in conjunction with the second pin (11).
