Plate augmentation leaving the nail in situ and bone grafting for non-union of femoral shaft fractures.

We reviewed 15 patients with femoral non-union after interlocking intramedullary nailing treated with plate augmentation and bone grafting with the nail in situ. The mean time from primary nailing to plate augmentation and bone grafting was 10 months. At the time of presentation, the patients had undergone an average of 1.6 operations from the time of their original injury. To achieve stability of the fracture, we applied an AO plate on the lateral aspect of the femur. The retained nail maintained alignment of the fracture, and plating did not require an extensive surgical approach. In all patients, there was visible motion at the fracture site; however, the motion disappeared after plate augmentation. All patients achieved radiological solid union at an average of 7.2 months.
