Thanks to an increasing life expectancy of our populations the number of elderly persons is steadily growing and will continue to do so. Among these, the rate of persons with illnesses and degenerative diseases is significant. The prevalence of osteoporosis is especially high in elderly women and leads to typical fracture patterns. Hip fractures, proximal humerus fractures, distal radius fractures and fractures of the vertebral column are the most common. In the last decade, we are confronted with a sharp increase of fragility fractures of the pelvis.
Until now, there is no consensus on how to identify and classify these lesions and there are no guidelines for treatment and after treatment. In particular, there is no common view on which patients need an operative treatment and which technique of osteosynthesis should be used.
This book fills the gap in available literature and gives a state of the art guide to the treatment of fragility fractures of the pelvis. With the sharp increase of these fractures and the lacking consensus, Fragility Fractures of the Pelvis will become indispensable for the physicians who take care of elderly patients with this pathology. Written by a team of expert opinion leaders, the aim of this book is to contribute to the scientific discussion in this area and to help provide the optimal care for these patients.
Professor Pol M. Rommens and Professor Alexander Hofmann are well-known and respected pelvic and acetabular surgeons. They have published numerous papers on the treatment and outcome of pelvic fractures, and developed a comprehensive classification of fragility fractures of the pelvis, combined with recommendations for treatment.
