Surgical treatment of both-column fractures by staged combined ilioinguinal and Kocher-Langenbeck approaches.

Between 1981 and 1989, 18 patients affected by both-column acetabular fractures were operated on by staged combined ilioinguinal and Kocher-Langenbeck approaches. Postoperative reduction quality and long-term radiographic results were evaluated according to the Matta radiological systems. The Harris hip scoring system was used for the functional results. Average follow-up was 53.2 months, ranging from 24 to 132 months. Reduction was anatomical in five cases (27.8 per cent), satisfactory in 11 (67.1 per cent), and non-anatomical in two cases (11.1 per cent). Radiographic long-term results were excellent in nine cases (50 per cent), good in five (27.8 per cent), fair in two (11.1 per cent) and poor in two (11.1 per cent). The Harris score was more than 90 in eight patients (44.4 per cent), between 80 and 90 in seven (38.8 per cent), between 80 and 70 in one (5.5 per cent), and less than 70 in two (11.1 per cent).
