Unstable pelvic fractures: a retrospective analysis

Abstract

Thirty-nine patients with unstable pelvic fractures were analysed retrospectively. The mean age of the group was 41 years (range 15–77). Of these cases 35 had sustained high energy trauma. The mean Hospital Trauma Index-Injury Severity Score of the population was 32 (16–66). Nine cases were haemodynamically unstable on admission. The type of unstable pelvic fracture was classified according to Tile. Sixteen patients had a type B fracture and 23 had a vertical instability (type C) fracture. In two patients, an open fracture was seen. Directly associated injuries were diagnosed in 11 patients, of which eight showed damage of the urogenital system, three of the rectum and three of the peripheral nerve system. In seven cases the fracture was treated non-operatively; in the remaining 32 patients the pelvic ring was stabilized operatively. Additional therapy for hypovolaemic shock due to pelvic bleeding was necessary in six cases. The overall mortality in this series was 13 per cent. Early and aggressive resuscitation and standardized treatment in well-equipped and staffed injury centres is mandatory in these severely traumatized patients to achieve optimal results and to minimize the risk of fatal outcome.
