Fractures of the acetabulum in elderly patients: an update.

The incidence of acetabular fractures in elderly patients is increasing. Poor bone quality and concomitant diseases are the main features of these patients. Fracture patterns are marked by a high degree of variability in terms of patient and fracture characteristics. Preoperative planning with plain radiographs and computed tomography, including 3-dimensional reconstructions, is recommended. Treatment remains challenging because of precarious general health, severe osteopenia, comminution, and associated femoral head damage. Treatment options available include closed management, open reduction with internal fixation, percutaneous fixation in situ, and acute or staged total hip arthroplasty (THA) whether alone or combined with osteosynthesis. In the case of significant destruction of the articular cartilage, primary THA may provide the best solution. Whichever surgical method is chosen, the objective is rapid mobilisation of the patient on a walker or crutches. Late local complications that may occur after nonoperative or operative treatment include posttraumatic arthritis, nonunion, malunion, wound infection, dislocation, intrusive hardware, nerve palsy, and heterotopic bone formation. In this article an overview of the current trends in the management of acetabulum fractures in the elderly is presented.
