Use of a retrograde intramedullary interlocking nail for the treatment of distal femoral fracture

Objective To assess the clinical outcomes of retrograde intramedullary interlocking nail(RIIN)for the treatment of distal femoral fracture.Methods Between June 2000 and December 2001,19 cases of fracture of distal femur were treated with RIIN. At surgery,The Merchan knee functional score were used to evaluate the results. Results The average duration of follow up was 18.5 months. 18 of all patients achieved solid bone union at an average of 5.3 months. There were no malunion,infection and refracture in this series. According to the Merchan knee functional score, the excellent result was obtained in 9 cases,good in 7 cases.Conclusion Retrograde intramedullary interlocking nail is one of the effective alteratives for treatment of distal femur fracture. It can provide a stable and reliable fixation which is of benefit for early functional exercise.
