As intramedullary nailing became more common in the treatment of femur shaft fractures, the incidence of nonunion increased which led to various treatment modalities for this complication. Accurate diagnosis of the etiology of nonunion and appropriate treatment is essential. Poller screws can help in preventing possible sagittal malalignment after intramedullary nail fixation and also be a minimally invasive method to treat hypertrophic nonunion derived from bone fragment mobility. We report 1 case along with literature review for the treatment of hypertrophic nonunion in femur.
