Treatment of geriatric pelvis fractures - What are the knowledge gaps?

The incidence of insufficiency fractures of the pelvis is rising in developed countries. The aim of this review is to summarize the current evidence regarding the classification, treatment, and surgical strategies for these fractures. Several classifications have been developed such as the AO Spine Sacral Injury Classification System, the Fragility Fractures of the Pelvis (FFP), and the OF pelvis classification. The treatment option consists of non-operative treatment, sacroplasty, ileosacral screw or rod fixation, lumbopelvic fixation and approaches to the anterior ring including fixateur externe or interne, pelvic plates or screw fixations. The advantages and disadvantages of each technique are depicted. The knowledge gap in this field is large and future directions are discussed.
