[Osteoporotic fractures of the pelvic ring].

Due to the aging population, we are confronted with a growing number of osteoporotic and insufficiency fractures of the pelvic ring. They are the result of a low-energy trauma. With conventional X-rays, it is not always possible to identify the lesions. In all cases, additional CT or MRI examinations are necessary. The morphology of the lesions is very variable and represents a spectrum of instability. Conventional classification is not applicable for all fracture types. Therapy includes a wide range between conservative and operative concepts. The choice of treatment is determined by the degree and the localization of the instability. Osteosynthesis techniques differ from the techniques we use in adults. The trans-sacral positioning bar, iliolumbar fixation and angle stable plate osteosynthesis are used increasingly often.
