RESUMO
INTRODUCTION: Tillaux Fractures are an infrequent type of fracture that occurs in teenagers. The mechanism is an external rotation that causes stress on the anterior tibiofibular ligament, which displace the distal tibial physis fragment. METHODS: 6 patients (5 girls and one boy), with an age between 12-14 years, who had Tillaux fractures with a displacement more than 2 mm; were treated by orthopedic reduction and fixation with a screw. RESULTS: After surgery patients underwent cast immovilization for 4 to 6 weeks; starting then progressive partial bear-weight. After a follow-up of 5-7 months, all patients have achieved complete and painless ankle mobility with radiological images of consolidation. CONCLUSION: Treatment by orthopedic reduction and internal fixation with a screw is suitable for Tillaux fractures with a displacement of 2 mm or more.
