FIELD: in medicine for compression osteosynthesis of bone fragments. SUBSTANCE: screw has a threaded portion, a head and a necking portion. It is made of material with shape memory property. The necking portion of the screw is deformed by tension. A ratio of a diameter of the deformed necking portion to a diameter of the necking portion before deformation is consists 0.7-0.9. EFFECT: enhanced structure of the screw for osteosynthesis. 1 cl, 1 dwg
