摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to traumatology and orthopedics, and can be used in methods of open reduction and fixation of shifted acetabular fractures experimentally. Method involves surgical approach, exposing the fragments of an acetabulum, their open reduction with fixation by screws and plates. Corpse is placed on its side； Harding outer-front access to the hip joint is performed, which is used for hip replacement. It involves anterior dislocation of femur. That is followed by femoral neck osteotomy. Hip head is removed, the trochanteric portion of the hip is withdrawn backwards. Further, an acetabular fracture of the B2.2 type according to the AO / ASIF international classification is modeled by osteotomy of the acetabulum with creating column diastase. At the next step, displaced columns of cotyloid cavity approach each other, achieving maximum accurate reposition. That is followed by placing a reposition-fixing support ring into the cotyloid cavity of the corresponding cotyloid cavity so that the first flange is above the upper edge of the cotyloid cavity, and the second flange is located at the junction of the ischial bone and the rear edge of the acetabulum, and the third flange is positioned to confine the front edge of the cotyloid cavity and the horizontal branch of pubic bone. Then the ring is fixed to the articular surface of the main fragment of the acetabulum linked to the iliac bone by inserting the screws through a group of holes of the support ring within the articular surface of the main fragment of the acetabulum. That is followed by successively introducing one screw at an angle into the posterior column through the corresponding opening of the ring and its articular surface, and into the front column through the corresponding opening of the ring and its articular surface, leaving part of each screw above the inner surface of the ring. Further, cotyloid cavity recomposition is continued by pulling the columns
