FFP type IIc. Initial diagnostics showed a unilateral fracture of the sacral ala right-sided and a displaced fracture of the anterior pelvic ring in this 83-year-old female (a).

She was stabilized subsequently with a trans-sacral bar and an anterior plate osteosynthesis (note the long screws reaching the posterior column) (c). A radiograph taken 5 months later demonstrated no implant failure or displacement; however, the patient sustained a pertrochanteric fracture due to recurrent fall (d)
