Background: Intramedullary nails have been widely used to treat long bone fractures, most of which heal within the expected time. However, in some cases union fails to occur by the expected time due to various reasons. After treatment with intramedullary nails, fractures located at the metaphysis of long bones are especially prone for non-union. The main reason for the non-union is instability (rotational) at the fracture site. The treatment options available to deal with such a situation include exchange nailing, removal of nail and re-osteosynthesis with plating, or Ilizarov fixation. Materials and Method: Our study is a prospective study conducted from AUG 2016 to AUG 2018, involving 10 patients. Patients with fracture shaft of femur treated primarily with intramedullary nailing were included in the study were included in the study. Results: All cases were followed up monthly upto 4 month and then every three months upto 1 year. All cases started showing signs of healing from eight weeks onwards and the fracture united radiologically at the end of 4 months. Conclusion: Our study concludes that augmentation plating gives excellent mechanical stability and improves the biology for fracture healing and when combined with exchange nailing it has a very high success rate and is a reasonably good, effective and safe procedure for non-unions following intramedullary nailing of femur shaft fractures.
