Outcome after pelvic ring injuries

Open reduction and internal fixation of unstable pelvic ring fractures provides the best stability of fixation as well as the best late clinical results. Whereas several studies have supported this both in biomechanical studies and clinical trials, there is still controversy about the long-term outcome of these injuries. A series of 58 patients who had received surgical stabilization of Tile B- and C-type fractures between 1985 and 1990 were followed up for an average of 28 months. The follow-up included a detailed clinical and radiological examination, an evaluation of the patient's general social status and a detailed neurological and urological screening. The data were summarized in a new scoring system rating radiological, clinical and social results independently. Patients suffering B-type fractures showed 79% good and excellent results. Despite the fact that after C-type fractures 50% healed anatomically and 30% healed with a 5 mm or less residual posterior displacement, only 27% of the patients were rated good or excellent. Further studies must be conducted for closer evaluation of risk factors influencing the results after anatomical reconstruction of the pelvic ring.
