Treatment of supracondylar femur nonunions with open reduction and internal fixation.

We reviewed a consecutive series of 22 adults with 22 supracondylar femoral nonunions treated with open reduction and internal fixation (ORIF) to determine the results and complications associated with the procedure. Twenty-one of 22 nonunions (95%) healed. Knee Society pain scores improved from 18 to 88 (P < 0.001). Mean Knee Society functional scores improved from 4 to 55 (P < 0.001). Mean range of motion at follow-up was 1 degree to 96 degrees. ORIF and bone grafting of properly selected patients with nonunions of the distal femur resulted in high rate of union with few associated complications. All patients had improvement in pain scores and the great majority had improvements in functional scores.
