An open fracture of the ulna with bone loss, treated by bone transport.

We report a Gustilo and Anderson IIIc fracture of the ulna with 8 cm of bone loss which was reconstructed primarily by the technique of external fixation and bone transport. Five operations were performed over a period of 14 months (treatment index = 52.5 days/cm). A satisfactory functional result was achieved, demonstrating the efficacy of this technique for difficult forearm reconstructions and comparing favourably with other methods of managing large bone and soft tissue defects.
