The present invention refers to an external tutor for treating fractures in the radius distal end, said type of external tutor contemplates the use of longitudinal pins to be inserted in the bone structure. Its main advantage is that it provides stiffness and stability to the fractured zone, allowing, in turn, a higher mobility if compared to traditional resources. It consists of a planar and elongated part, comprising a body and a head articulated to it. Both the head and the body have orifices which are run through by the pins, which are withheld by pressure fitting-up bolts integrally lodged into threaded orifices matching said orifices through which the pins run through. Since the passing orifices in the head are oblique, both the pins and the tutor as a whole define a structure of triangular conformation.
