Objectives: The aim of the treatment of tibial plateau fractures is to obtain a pain-free and fully functional knee with closed reduction, percutaneous cannulated screw fixation and hexapodal external fixator reconstruction for high energy compound upper tibial fractures. Methods: Patients with comminuted tibial plateau fractures underwent closed reduction, percutaneous fixation with cannulated screws, and reconstruction with hexapodal external fixator. The follow-up period was 24 months. Results: The clinical and radiological results were good or excellent. The average knee flexion was 125°. Conclusion: Our results are successful in the initial stage, however, it should be pointed out that during the long term follow-up osteoarthritis may develop leading to worsening of the condition. Level of Evidence IV, Case Series.

OBJETIVO: Avaliar a eficácia do tratamento da fratura em martelo, pelo método de Ishiguro de bloqueio de extensão com fio de Kirschner. MÉTODOS: Trinta e oito pacientes foram tratados prospectivamente. O acompanhamento médio foi 18 meses e todos os pacientes foram avaliados radiológica e clinicamente, de acordo com os critérios de Crawford.
