RESUMO
Objective To study the effect of internal fixation of fibula on treatment of tibia and fibula unstable fractures. Methods 50 cases with middle and lower 1/3 fractures of tibia and fibula were treated with internal fixation of fibula and close reduction and external stabilization of tibia. Fibula was stabilized with plate and screw or intramedullary nail. Results All the 50 cases of the fracture achieved clinic union, reduction was satisfactory, and the average time of clinical union was 5 months. The functions of the joint were normal. No skin necrosis or infection occurred. Conclusion Fixation of fibula is suitable for treatment of close fracture combined with local skin injury or open fractures of tibia and fibula and lower 1/3 comminuted fracture of tibia combined with fibula fracture.
