Background and Aim: Femoral fractures occur in 37 per 100,000 people per year. Distal femoral fractures are one of the challenging therapeutic facts, because of its high complications. So, many techniques have been introduced for its treatment. Up till know, there is no comparative study on Retrograde Intramedullary Nailing (RIN) and Locking Condylar Plate (LCP) in

Iran and the results of this study may help surgeons to evaluate the real success in these procedures.

Patients and Methods: In this observational-analytic-cross-sectional study, 38 patients who had undergone RIN or LCP during 2005-2007 were evaluated. The patients were called to come to clinic for re-evaluation of mobility and any possible deformity. For statistical analysis Pearson's correlation, dependent t-test and Chi-sqaure test was used. SPSS V. 16 was also used for data analysis.

Results: The distribution of age and gender were the same in two groups. The means of range of motion (ROM), duration of :::union::: and reoperation were similar as well. The frequencies of knee pain and septic knee were higher in patients who underwent RIN, but mal:::union::: was higher in LCP group.

Conclusion: According to results of this and previous studies, LCP is the recommended technique in distal femoral fractures. We found that the result of RIN was poorer in

Iran than other countries. We suggest further prospective studies with more sample size in this regard.
