[Our experiences with change of osteosynthesis from external fixator to internal fixation in fractures of the lower limb].

INTRODUCTION

In polytrauma patients and fractures with severe soft tissue damage of the lower limb the use of external fixator is indicated. To show the possibilities and limits of change of external fixation to internal osteosynthesis we performed a retrospective analysis.

PATIENTS AND

METHODS

Between 1.1.1993 to 30.6.1997 671 cases were primarily treated with external fixator. After a mean of 16.5 days a change of osteosynthesis was performed in 75 cases.

RESULTS

5 infections of the pin tracks, 3 infections of the wound, two thromboses, one case of thromboembolism and one osteomyelitis were seen in these 75 cases. One patient died due to severe brain damage after head injury. No further operations were necessary, all fractures showed primary healing. Taking the severe soft tissue damages and severe multiple trauma into account only few complications were observed.

CONCLUSION

The main problems and risks of internal fixation occur in the early phase of treatment, whereas complications after external fixation are more likely to occur in later stages. By a change from external fixation to internal osteosynthesis the advantages of both methods can be combined.
