[Operative treatment of complicated distal femoral fractures]

To explore an effective way for treating severe complicated distal femoral fractures.

Twenty-six patients with complicated distal femoral fracture who all belonged to 33C3.3 type according to AO/ASIF classification, were treated with a lateral condylar buttress plate or self-designed aliform anatomical plate, and operated on with allogeneic bone grafting.

All cases were followed up for an average of 14 months (ranging 5-25 months). Twenty-four wounds were primary healing postoperatively, 2 wounds were infected and healed after dressing change. Twenty-four had bone healing after 4-11 months, 2 needed to operate again because of earlier weight-bearing resulting in fixation failure. According to shelbourne and Brueckmann score, the excellent and good rate was 88.46%.

The internal fixation for complicated distal femoral fracture by self-designed aliform anatomical plate and lateral condylar buttress plate with a great deal of allograft bone is an effective surgical method. As it has long oval holes and the holes are consecutive, the aliform anatomical plate is more suitable for severe complicated fractures. At the same time, autogenous-ilium transplantation can be substituted by the allograft bone.
