[Fragility fractures of the pelvis].

Fragility fractures of the pelvis are increasing in frequency. In most cases patients suffer a minor injury, have intense pain in the pelvic region and impaired mobility. The new fragility fractures of the pelvis (FFP) classification distinguishes between four types with increasing instability. The FFP types I and II are treated conservatively. For FFP types III and IV and type II with unsuccessful conservative treatment, minimally invasive stabilizing techniques are recommended. Both the posterior and anterior pelvic ring must be stabilized. Alternative techniques for dorsal stabilization are iliosacral screw and transsacral bar osteosynthesis, transiliac internal fixator and lumbopelvic fixation. External fixation, retrograde transpubic screw fixation, anterior internal fixation and plate and screw osteosynthesis are alternatives for the anterior pelvic ring. Treatment of fragility fractures of the pelvis should be carried out as part of an orthogeriatric co-management.
