AO less invasive stabilization system for treatment of distal femur fractures

[Objective]To report short-term outcomes of treatment of distal femur fractures with Less Invasive Stabilization System (LISS) and introduce the operation problems of LISS with related literature review.[Method]Four cases of distal femur fractures were reviewed, of which 2 cases were left and 2 were right. The age was from 36 to 53 years. The causes of the injuries were vehicle crashes for 3 cases and weight impression trauma for one case. AO fracture classification: A-type in two cases and C-type in two cases. All the patients were treated by LISS.[Result]All patients were followed-up for a period ranged from 3 to 6 months (averaged, 4 months). According to the scoring systems of Merchan, three patients had an excellent functional result, one patient had an good functional result.[Conclusion]LISS is an effective and minimally invasive method for the treatment of distal femoral fractures. There is usually no need for primary cancellous bone grafting, and fewer complications were observed postoperatively.
