Background: The open fracture of femur and leg is one of the most common fracture of orthopedic injuries. Utilization of external fixator has worldward acceptance. Pin tract infection, neurovascular injuries, compartment syndrome are common complication of this injuries. In this research complication and other pitfall treatment of has external fixator insertion were studied.

Material and Method: Is this study the patients with open fracture of periarticular fracture of knee and ankle were studied. One day after surgery the neurovascular injury has studied and when patients referred for exchange of external fixator the pin tract infection has studied.After data gathering by observation and checklist they analyzed by means of independent t-test and spss20.

Results: The rate of infection was %52. The rate of neurovascular injuries was %6. The rate of compartment syndrome and vascular injury was zero and the rate of tendon injury was %5.7. In comparison between pin tract infection and neurovascular injuries and tendon injury in open and close fracture only the injury of nerve has meaningful differences( P=0/049). In our study the kind of dressing (with Betadine) and kind of pin (stainless steel) was appreciated.

Conclusion: External fixator placement for open or comminuted fractures of the femur and leg is associated with a considerable degree of pin tract infection, but neurovascular effects and complications of tendon muscle, compartment syndrome is uncommon.
