Fragility fracture of the pelvis (FFP) classification. The FFP classification is outlined according to the characteristic fracture morphology. The main lesions are in red and the less common lesions are in orange. Non-operative treatment is recommended for FFP I and FFP II. Operative stabilization is recommended for FFP III and FFP IV. FFP II with prolonged pain or restricted mobilization should be considered for operative treatment as well.
