Management of tibial fractures with the orthofix dynamic external fixator

We report our experience with the use of the Orthofix external fixator for the management of closed and open tibial fractures. One hundred fractures were treated in 96 patients between May 1985 and December 1989. There were 47 closed and 53 open fractures. Of the open fractures, 11 were grade I, 16 were grade II and 26 were grade III. Forty-five closed fractures and 49 open fractures went on to solid bony union in an average of 15.2 and 20.5 weeks, respectively. Non-union requiring operative intervention occurred in two closed and four open fractures (6%). The other main complications were pin track infection (30% of cases) and malunion which occurred in 14% of closed fractures and 32% of open fractures. We concluded that dynamic axial fixation is a useful method of treatment for open and difficult closed tibial fractures. Our experience indicates that malunion and pin track infection remain common problems and have still to be overcome.
