Objective: To evaluate the effect of auto graft use on union time and knee functions in patients treated with retrograde intramedullary nails for the treatment of nonunion after locking plates, which are commonly used today in distal femur fractures. Materials and Methods: A retrospective study of 18 manufacturers with no intramedullary internal localization and no femoral union was studied. All people with nonunion in the 1/3 distal and without active signs are taken care of. At the end of 9 months, no sign of union and grown with intramedullary civilian after implant training were examined. Evaluation and value of union were evaluated. Continuous concordances Student’s t-test compared. P value <0.05 was considered significant. Results: The mean follow-up period of the patients was 24.7 (12-36) months. Varus deformity was observed as a complication in 3 patients. Based on the Mize score of the patients, good results were obtained in 12 patients, excellent results in 3 patients, and reasonable results in 3 patients. Considering the mean union times, it was 5.2 (4-7) months. The mean maximum knee flexion was 91.7 (10-120) degrees preoperatively and 106 (70-120 degrees) postoperatively. No significant difference was observed in terms of union time in auto graft use. Conclusions: Successful results can be obtained with retrograde intramedullary nails as a treatment option in distal femoral nonunions. Although the use of auto graft does not affect the result in terms of union time, more studies on this subject would be beneficial.
