摘要：
FIELD: medicine.SUBSTANCE: reposition-fixing support ring for surgical treatment of displaced acetabular fractures has a concave shape and holes for insertion of screws. Ring has shape of a hemisphere, external and internal surfaces, two rows of holes in a hemisphere and three flanges with holes for introduction 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 acetabulum and the inferior endostane of the ilium. 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 the ring is located on that part of the outer surface of the hemisphere, which corresponds to the point of confluence of the front edge of the cotyloid cavity and the horizontal branch of pubic bone and is located on the line connecting the middle of the fusion point of the front edge of the cotyloid cavity and the horizontal branch of pubic bone and the posterior lower tip of the 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, which enhances fixing capabilities of ring. First row of holes is located on one line along the edge of the ring inlet, 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 hole
