A novel feasible technique for rapid removal of broken proximal femoral nails: A case series

Proximal femoral nail (PFN) fixation is a technique widely used to treat various femoral fractures, but femoral re-injury may occur, leading to PFN breakage. Broken nail removal, particularly removal of the distal broken nails, is usually challenging. Herein, we describe a feasible approach to successfully remove broken femoral intramedullary nails in three sites (proximal, middle, and distal section) of the PFN. Three patients required surgery for PFN breakage. We performed a novel technique using minimal exposure and a cerclage wire to remove the PFN fragment, which a distal knot on the wire was applied to hold the PFN fragment, and the removal trajectory was completed through the minimal exposure, a distal femoral bone window, and the marrow cavity. We successfully operated these three patients and removed the PFN fragments rapidly and effectively. In conclusion, this novel technique is rapid, feasible, and cost-effective, and can also be promising in removing intramedullary nail breakages in other long bones.
