Background: Despite the advances in techniques and the improvements in surgical implants, treatment of distal femoral fractures remains a challenge in many situations. Long-term disability can still occur if inappropriate treatment is done. This study was conducted to evaluate the results of distal femoral nailing in treatment of the distal femur fractures.

Methods: In this cohort study, among patients referred to Kashani hospital in Isfahan, Iran from December 2005 to December 2007, 36 patients with distal femoral fracture were enrolled in our study. Patients were treated with retrograde femoral nailing. The patients' demographic information, Anterior Cruciate Ligament (ACL) tearing, duration of surgery, volume of hemorrhage, and after-surgery complications such as stiffness, infection and rate of union was obtained and reported.

Findings: The mean of time of surgery was 97.4 ± 11.6 minutes. There were not any ACL tearing in studied patients. In first two weeks, infection was seen in 4 patients that recovered. The rate of union was 100% after 6 month.

Conclusion: Regard to results, retrograde nailling has very good results in treatment of distal femoral fractures.

Key words: Distal femoral fracture, Retrograde nailling.
