Abstract:

[Abstract] Objective To summarize complications and early clinical effect of less invasive stabilization system and the femoral condylar support plates in treatment of AO type C distal femoral fractures. MethodsWe reviewed46patients who had internal fixation of AO type C distal femoral fractures. Of all46patients,25were with less invasive stabilization sys? tem and 21were with femoral condylar support plates fixation. Comparative analysis was performed using intraoperative in? dex, postoperative complications and the Evanich score at follow- up. Results All46patients were followed up with a mean time of19.6months after surgery. The difference in incision length, blood loss, fracture healing time was significant between the2groups（P<0.05）but not in the duration of operations and hospital stays（P>0.05）. The statistical signifi? cance was also found in the total incidence of postoperative complications and the Evanich score at the last follow-up（P< 0.05）. Conclusion Patients with less invasive stabilization system fixation had the characteristics of less trauma, shorter fracture healing time, less postoperative complications and better functional recovery compared with femoral condylar sup? port plates. Less invasive stabilization system had became an ideal internal fixation in treatment of AO type C distal femoral fractures.
