The role of the retrograde nailing in distal femur fractures: about 7 cases

We report a series of seven cases of fractures of the distal end of the femur treated by retrograde centro-medullary nailing in the Orthopedic-Trauma Department at the Hospital Ibn Sina over the period 30/05/2010 - 30/04/2015. The average age of patients was 54 years, with a slight male predominance (57,1%). Road traffic accidents were the main cause of these fractures (71.4%) and they mostly affected the right side of body (57,1%). From a surgical point of view, the mean time between symptom onset and treatment initiation was 2 days. Spinal anesthesia was performed in five cases. The average length of stay in hospital was 5 days. The mean time of consolidation was 4 months in all patients, there was only one case of delayed consolidation (6 months). Patients had good functional outcomes with mean knee flexion 120 degrees, with only one case of limited flexion 90 degrees. There was one case of consolidation delay and one case of pseudarthrosis. No deaths, or superficial or deep sepsis, or thromboembolic complications or fat embolism were registered. In general we had satisfactory outcomes. Our study highlights that retrograde femoral nailing is an essential osteosynthesis technique for the surgical treatment of the distal femur fractures.
