Abstract
The invention concerns an external fastening device for reducing bone fractures (6 and 6'), comprising two pairs (A and B) of rings (1) which are each provided for a bone stump (6 and 6') and in which the rings (1) are secured coaxially to each other and are locked on the relevant bone stump (6 and 6'), thanks to the positioning through the bone of small rods or subtended wires (7) which intersect inside the bone section and are tightened at opposite points of the ring (1) connected to them by means of clamps (9), whereby each pair (A and B) of rings is supported by a clamp (13a and 13b). The relevant displacements of the single pairs (A and B) of rings (1) are controlled by a single integral control unit (14). Thanks to this unit (14), a pair (A) of rings (1) can be moved in both directions lengthwise (L) and can be moved angularly, in both directions (R), around an axis orientated in the sagittal direction (S), while the other pair (B) of rings (1) can be moved, in both directions, in the sagittal direction (S) and in a transverse direction (T) and can be rotated, in both directions (P), around an axis orientated in a transverse direction (T).
