Free vascularized fibular grafts in the treatment of congenital pseudarthrosis of the tibia.

Five patients with congenital pseudarthrosis of the tibia treated by a free vascularized fibular graft are described. Follow-up evaluation ranged from 15 to 81 months, with a mean of 40 months. Bony union was attained in three of five cases as determined roentgenographically. The remaining two cases failed to attain bony union. All cases except one, who was treated with a below-knee amputation, subsequently attained bony union. However, four cases had five fractures after bony union. We discussed unsolved problems regarding the free vascularized fibular graft and fracture after bony union.
