ABSTRACT:
A device for the gradual correction of a bone fracture which has already been set in the operating theatre comprises an elongated structure (1) which defines a longitudinal axis (L) which can be positioned parallel to the bone and comprises a pair of end supports (10, 11) releasably anchored to corresponding bolt-bearing end clamps (6, 7) of an external fixation unit (2) which has already been fitted to the fractured pieces (F1, F2), a central body (24) connected to supports (10, 11) by connection means formed by longitudinal (32) and transverse (25) adjustment means to correct the longitudinal distance and transverse offset between the supports respectively, angular adjustment means (39) to correct the relative inclination of one of the supports with respect to the longitudinal axis (L) rotating it about a transverse axis (T), and centering means (40, 49, 50, 51) to align the transverse axis (T) with the centre of the fracture. The transverse axis (T) is perpendicular to the plane of action of the longitudinal (32) and transverse (25) adjustment means.
