Background: The indication for osteosynthesis with a retrograde intramedullary nail in femur fractures has increased in recent years and with it, the number of complications. Three surgical techniques are described for the management of the proximal fragment of the broken intramedullary osteosynthesis. From March 2001 to January 2019, 321 osteosyntheses with retrograde femoral intramedullary nails were performed at our institution. The implant rupture rate associated with nonunion was 0.9%. Minimally invasive techniques were performed to remove the implant, preserving the soft tissues. Definitive reosteosynthesis was achieved with the consequent consolidation in an average time of 140 days. Conclusions: The techniques used were simple, safe, minimally invasive, and reproducible.
