RESUMEN
Objective To assess the clinical outcome of retrograde intramedullary interlocking nail in the treatment of femoral suplracondylar or intercondylar fracture with femoral shaft fracture.Methods 3 cases of femoral supracondylar fracture with femoral shaft fracture and 6 cases of intercondylar femoral fracture with femoral shaft fracture experienced the fixation with retrograde intramedullary interlocking nail.Results The patients were followed up for 7～ 20 months,on an average of 10 months.All the patients recovered in an average time of 6 months,with excellent knee joint movement.Conclusion Retrograde intramedullary interlocking nail has obvious advantages in the treatment of femoral supracondylar or intercondylar fracture with femoral shaft fracture and the clinical outcome is satisfactory.
