title: Treatment of femoral diaphyseal nonunions.
abstract: There have been conflicting reports regarding treatment of femoral diaphyseal nonunions using reamed intramedullary nailing. Although high union rates have been reported using this technique, not all orthopaedic surgeons have experienced the same success. A retrospective review of charts and radiographs of 39 adult patients with nonunions of the femoral diaphysis treated at the authors' institution with reamed intramedullary nailing, compression, and with and without interlocking was done. The time from the index procedure to nonunion repair was 4 to 75 months (average, 19 months). Fifteen patients had 18 procedures between the index operation and nonunion repair. The average followup from nonunion repair to the most recent examination was 22.5 months (range, 3-108 months) with a median of 15 months. At the last followup, the overall union rate was 74% after one procedure and 97% after two or more procedures. There were seven complications including two infections, one pulmonary embolus, one occurrence of a deep venous thrombosis, a hematoma, and one case of malrotation. The data support the use of antegrade reamed nailing as a successful technique for treatment of most femoral diaphyseal nonunions.
