FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. A bone plate for the interaction with bone screws includes a mainly elongated body from a tissue-compatible, mainly rigid material, determining the plate plane and longitudinal axis, openings across the plate plane, consisting of the first and second round holes, crossing with the formation of edges, and a single rounding radial rib in both the round holes which deviates from their walls and passes around the holes in one plane to their centre. The first round hole is larger than the second round hole. The screws consist of a head and a rod for the fixation of parts of a fractured or injured bone. A rounding rib in the first round hole with an impact of the bone screw is made with a possibility of tightening with the thread, made on the screw head. The fixing system with the bone plate and bone screws for the fixation of bones, in which the said bone plate and, at least, two types of the bone screws, namely the bone screws with a partially spherical lower side of the head and the bone screws with the thread on the head, can be used.

EFFECT: inventions provide the possibility to use the bone screws of different types - with conic and spherical mounting surfaces to satisfy various requirements in the fixation of a fractured or injured bone.
