The long-term results of traumatic posterior dislocation of the hip

Out of a total of 91 patients with traumatic posterior dislocation of the hip treated between 1936 and 1974 in the Mansfield area, 81 patients were reviewed. The average follow-up period was 12.5 years, although there was a large number of cases with a follow-up of more than 15 years and a smaller number with a follow-up of 30 years. The overall results were surprisingly poor despite early reduction of the dislocation in the majority of cases. We found that 15 years after simple dislocation 24 per cent of the cases had a poor result by both clinical and radiological criteria, but in the more severe grades of initial injury the results became worse, with 73.3 per cent of the patients graded as fair and poor, and only 26.7 per cent graded excellent or good.
