The number of hip fractures in the elderly elevates as life expectancy increases. Therefore it is not infrequent to observe a femur fracture, distal to a previous proximal femur fixation (dynamic hip screw or fixed angle plate) used in intertrochanteric femur fractures, despite the reported annual mortality rate of 30-50% in patients with a femoral fracture. Given this situation, we used a retrograde intramedullary nail together with the percutaneous removal of previously implanted screws. We present eight cases of peri-osteosynthesis fractures in patients with an average age of 85.6 years (5 women and 3 men) and an average time from the proximal femur fixation to the new fracture of 3.5 years. The follow-up was 36 months and postoperative motion and pain were evaluated. Consolidation of the fracture was achieved in all cases. We found this technique effective; it was possible to achieve a stable fixation without adding morbidity due to the possibility of overlapping two implants, thus reducing the potential risk of a new fracture between implants.
