FIELD: medical equipment.

SUBSTANCE: invention relates to a device for primary stabilization of pelvic fractures. Device consists of Schanz pins and two 235 mm beams, a bolt, nuts, a threaded rod, brackets of washers from the Ilizarov apparatus. Two 235 mm beams have holes for connection and fixation with a bolt in the form of a lever of the second kind with a nut to change the angle between beams from 100 to 160 degrees.
