Y-SHAPED PLATE FOR OSTEOSYNTHESIS OF EPIMETAPHYSEAL FRACTURES (VARIANTS) Russian patent published in 2005 - IPC

FIELD: medicine, traumatology, orthopedics.

SUBSTANCE: the present innovation deals with metalloosteosynthesis of intra-articular and peri-articular fractures. According to the first variant, the suggested plate contains an osseous plate with openings and a fixing unit as a fork with teeth and foramens for a screw. Osseous part of teeth, branching fan-shapely, circles metaphysis and has a curvature at the angle of 180°. Submergible parts of teeth are parallel to each other. Teeth are designed to be round in cross-section. Teeth are being in a plane parallel to that of osseous plate. The length of submergible part of teeth knowingly exceeds the diameter of a semilunar fragment of patient's elbow bone. According to the second variant, the plate contains an osseous plate with openings and a fixing unit as a fork with teeth and foramens for a screw. Osseous part of teeth, branching fan-shapely, circles metaphysis. Submergible parts of teeth are parallel to each other. Teeth are designed to be round in cross-section. The distance between submergible parts of teeth is 1.5-2 times higher against the width of an osseous plate. According to the third variant, the plate contains an osseous plate with openings and a fixing unit as a fork with teeth and foramens for a screw. Perosseous part of teeth, branching fan-shapely, circles metaphysis, and submergible parts of teeth are being parallel to each other. Teeth are designed to be round in cross-section. The plate has a curvature according to the shape of condylar edge of patient's brachial bone. Osseous part of teeth is supplied with a crosspiece to provide the chance to be fixed up with screws.

EFFECT: higher efficiency of osteosynthesis.
