Background: the antegrade intramedullary reamed nailing is the method of choice for treating diaphyseal femoral fractures. Nevertheless, the retrograde technique has emerged as an alternative for situations in which the antegrade one presents certain disadvantages. Methods: between March 2001 and January 2011, 110 femoral retrograde nailings were performed. Thirty-four were performed in patients with diaphyseal femoral fractures. Mechanisms of injury were vehicular collision (15 cases), low energy trauma (18 cases) and ballistic trauma (1 case). Eleven patients (31%) presented associated injuries. Results:  thirty-three patients achieved consolidation (97%). Healing after procedure occurred at 84 days for the reamed group and 112 for the undreamed one. We had one case of consolidation delay that was resolved inserting a larger diameter reamed nail together with autologous graft. The average range of motion was 130o of flexion (minimum 100o, maximum 150o). Six patients (17.6%) reported knee pain. Conclusions:  the retrograde nailing for diaphyseal femoral fractures yields consolidation results similar to those of the antegrade nailing. The possible advantages are: simple technique, the avoidance of traction table use during surgery and shorter surgical time.
