摘要：
FIELD: medicine； medical equipment.SUBSTANCE: invention refers to medicine. Reposition-fixation support ring for surgical treatment of shifted poly-fragmentary acetabular fractures has a concave shape and holes for inserting screws, has the shape of a hemisphere, external and internal surfaces, two rows of holes in the hemisphere and three flanges with holes for insertion of fixing screws. Flanges are located on the external surface of the hemisphere so that when the ring is placed in the cotyloid cavity two of them are located on the same line connecting the middle of the junction point of the ischial bone and the lower edge of the cotyloid cavity and the inferior spine of iliac bone. First of two flanges is located on that part of external surface of hemisphere of ring, which corresponds to place of upper edge of cotyloid cavity. Second of the two flanges is located on that part of external surface of the hemisphere of the ring, which corresponds to the junction of the ischial bone and the lower edge of the cotyloid cavity. Third flange on ring is located on that part of outer surface of hemisphere, which corresponds to confluence of anterior edge of cotyloid cavity and horizontal branch of pubic bone and is on line connecting midpoint of confluence of front edge of cotyloid cavity and horizontal branch of pubic bone and posterior lower spine of iliac bone. Plane of the first flange is at an angle to the plane of the ring inlet. Plane of the second and third flanges of the ring is in the same plane as the plane of the ring inlet. Holes of three flanges allow additionally fixing fragments of cotyloid cavity to reposition-fixing support ring. At the ring, the first row of holes is located on one line along the edge of the ring entrance, from the edge to the center, and the second row of holes is located on one line, from the first row in the direction towards the hemisphere center. Holes of the second row are located relative to holes of the first row in staggered o
