[Treatment of Periprosthetic Distal Femoral Fractures].

CONCLUSIONS The number of PDFF has been increasing. The main methods of internal osteosynthesis continue to be the angular stable plates and the retrograde femoral nail. Preoperative planning is important to determine the type and dimensions of the existing femoral component and to distinguish whether or not it has come loose. The choice of the implant may depend on the bone mass available for distal fixation. The retrograde femoral nail is usually the most suitable method of treatment for proximal PDFF (Su Type I). The angular stable plates can be used for PDFF originating at the femoral component (Su Type II and Type III). Very distal fractures classified as Su Type III with a loose femoral component require a revision surgery with a TKR with stems. The surgeon should be prepared for a revision surgery if the intraoperative finding is more complicated than anticipated based on the preoperative radiograph.
