Retrograde femoral nails for intercondylar femoral fractures

Abdelsalam Eid, Shamel Elgawhary


Introduction: Intercondylar femoral fractures require much effort to anatomically reduce the articular surface and to obtain stable ixation to allow knee movements until fracture healing. Open reduction and plate fixation is usually done. MIPO is becoming popular, particularly with locked plates. However, some authors reported the successful use of supranails in intercondylar femoral fractures. Material and methods:Ten patients with intercondylar femoral fractures AO Type C2 were treated by fixation using a retrograde femoral nail after fixing the condyles with a cannulated screw. Results: All fractures united, including one delayed union that required a bone graft without change of fixation. Mean time to clinical union was 3.8 months. Mean time to radiological union was 5.4 months. According to the modified HSS knee score the mean level of pain was 31.5. Eight patients had a knee ROM > 90°. Two patients had extension lag of 10°. Three patients had minor residual valgus, one had minor residual varus. The mean modified HSS score was 82.6. Conclusion: Retrograde femoral interlocking nails could effectively fix intercondylar femoral fractures until union occurs.
