OBJECTIVE The aim: To analyse the results of the delayed acetabulum posterior wall fractures treatment and to identify the negative factors affecting the outcome. PATIENTS AND METHODS Materials and methods: The patients' treatment results have been assessed in 5 years after the surgery. The surgery was performed in 21 to 120 days after the injury, 44±11 days on average. 23 individuals (19 men and 4 women) were included in the retrospective analysis. RESULTS Results: Anatomical fracture reposition was achieved in 12 (52.2%) cases, imperfect but satisfactory reposition - in 7 (30.4%) cases. 4 (17.4%) cases resulted in unsatisfactory reposition. Hip arthroplasty was performed in 5 patients over the following 5 years. CONCLUSION Conclusions: The delayed fractures of the acetabulum posterior wall (21 to 120 days after the injury) is the complicated task for a surgeon. The aseptic necrosis and deforming arthrosis were found in 1-5 years after treatment. The preparation for the anatomical reposition takes a big amount of time and effort from the orthopedic team because of technical peculiarities.
