We evaluated the effect of revision with dynamic compression plate and cancellous bone graft for aseptic nonunion after intramedullary nailing of femoral shaft fracture. Fifty patients with aseptic nonunion of femoral shaft fracture after intramedullary nailing were reviewed and analyzed retrospectively between 1996 and 2007. There were 40 men and 10 women with an average age of 44 years (range, 19-76 years). Thirty-five were diaphyseal fractures, 8 were distal fractures, and 7 were proximal fractures. Twenty-eight fractures were defined as atrophic nonunion, 13 fractures were hypertrophic nonunion, and 9 fractures could not be defined clearly. All fractures were managed by retaining previous implants, open reduction and internal fixation with dynamic compression plate, and supplementation by cancellous bone graft. The average follow-up period was 76 months (range, 24-128 months). Functional evaluations were done by Harris Hip score and Hospital for Special Surgery knee score. All nonunions united on average at 24 weeks (range, 18-32 weeks). One superficial wound infection occurred. At follow-up, each patient was evaluated to have satisfactory function results, with near normal hip/knee functions without noticeable pain, and full return to preinjury activities/work without pain.Augmentative dynamic compression plate with cancellous bone graft is a reliable and effective treatment for revision of aseptic nonunion of femoral shaft fracture after intramedullary nailing.
