ORTHOPEDIC EXTERNAL FIXATION SYSTEM FOR THE TREATMENT OF COMPLEX FRACTURES UNDER PRECARIOUS SURGICAL ENVIRONMENTAL CONDITIONS

摘要

The present invention relates to an integrated orthopedic external fixation system (1), for the treatment of complex or displaced fractures under precarious environmental conditions, of the type comprising an external fixator (2, 2') and a plurality of bone screws (3, 3') for fixing the fixator to a fractured long bone. Advantageously, the system (1) according to the present invention comprises: a pair of cylindrical portions (4, 5) interconnected coaxially together by means of interlocking connection means (6, 7) able to adjust the movement towards and away from each other of these portions (4, 5); a plurality of through-holes (16, 16') formed transversely with respect to the axis (X) of the body of the fixator (2, 2') and at a predefined distance from the opposite free ends (21, 22) of the fixator (2, 2'), for receiving a respective bone screw (3, 3'); each bone screw (3, 3') having a smooth cylindrical central section and being slidably engaged in a guided manner inside the corresponding hole (16, 16') of the body of the fixator (2, 2'); a threaded front tip portion, intended to come into screwing engagement with said long bone, in a substantially self-tapping manner; and a threaded rear tail portion intended to come into screwing engagement with the corresponding hole (16, 16') of the fixator body (2, 2'), in a substantially self-tapping manner.
