Revision surgery for femoral shaft aseptic nonunion associated with broken distal locked screws

Using exchange locked nailing or one-stage femoral lengthening to treat femoral shaft aseptic nonunion associated with broken distal locked screws can achieve a high success rate. The key of the technique to remove broken screws is withdrawing the nail a little bit to release the incarcerated broken screw end. Then, the screw end is pushed out with a used Knowles' pin or a smaller size screwdriver under the image intensifier guidance.
