title: [An analysis of surgical treatment methods in femoral neck fractures based on a patent information search].
abstract: Patent inventive discoveries in the USSR over the period 1949-1989 are analyzed together with the world patent discoveries, inventions, designs (Ukraine since 1989 included) over the period 1978-1998, which are divided into several groups different in principle, criteria of analysis are singled out, new notions of "cruel", dosage, dynamic compression are determined. By making use of principles of biological low-invasive metallo-osteosynthesis and new notions of "cruel", dosage, and dynamic compression optimal options were found for fixation of fractures of the femoral neck: low-traumatic nail set in the neck at an angle of 130 degrees fit with a small-sized diaphyseal put-in lamina and a local stimulation of union or spongiosa for the neck of the femur screw with an attachment preventing caput femoris rotation, and a springy element combined with a small-sized diaphyseal put-in lamina (that is, a modified system of the dynamic screw for the neck of the femur).
