[Therapeutic problems of acetabulum fracture in polytrauma].

Fractures of the pelvis and the acetabulum now occur more frequently in multiple injured patients. Anatomical and biomechanical considerations have led to special classifications of acetabulum fractures and to clear indications of operative stabilization. Because of the difficulty of operation including good preparation the biomechanical concept in treatment often must be modified, especially in patients with multiple injuries. 12 multiple injured patients with acetabulum fractures underwent operative stabilization of this fracture during the last 2 years. Nearly all types of fractures were seen. The acetabulum fractures more frequently showed difficult forms than otherwise reported. Sometimes the severe condition of the patient prevented an optimal treatment according to biomechanical points of view. Very often the operation was considerably delayed by general or local problems of the patient. The concept in diagnosis and indication of operation and the problems of operative treatment are demonstrated by the aid of several cases.
