The present invention relates to reduction and fixation of bone fractures of distal radius and wrist. The invention enables to mobilise the distal fragment in 3 planes and also to correct rotational deformity. The object of the present invention is to realize an external fixator which enables to reduce a fracture and at the desired position and fix the fracture. In case of unsuccessful reduction attempt for the second trial there is no need to dismount the fixator. Another object of the present invention is to realize an external fixator which enables to reduce a fracture in 3 dimensions and to correct the rotational deformity in a preferred degree. Another object of the present invention is to realize an external fixator which can practically be mounted to malunion zone and can be used for reducing in corrective osteotomy operations.
