FIELD: medical engineering. SUBSTANCE: device has concave inferior surface and lateral notches on its sides. The plate has a row of holes for receiving screws having spherical supporting head part with inclined shaped surfaces symmetrically arranged in them for creating compression in required side when crewing the screw in or out, and central recess for fixing screw head. The central recess is designed as paraboloid of revolution so that the screw head is sizable in it when being screwed in under corresponding inclination angle. EFFECT: high stability of bone fragments fixation. 1 dwg
