Objective To review the latest research progress of fixation techniques of ankle arthrodesis.Methods The l iterature concerning the research of fixation techniques of ankle arthrodesis in recent years was reviewed. Then the characteristics and new research progress of different internal and external fixation techniques were analysed and compared. Results There are plenty of different types of internal and external fixation devices, each with distinct characteristics. Now it is widely considered that internal fixation is the first choice for end-stage ankle arthropathy. However, under the circumstances that patients with serious bone defect, chronic active infection, or extensive soft tissue damage are not suitable for internal fixation, ankle arthrodesis with external fixation is still a safe and effective method. Conclusion For severe or end-stage ankle arthropathy, ankle arthrodesis is a mature therapeutic way with exact effect. Researches on these two aspects, expansion of indications of internal fixation and comparison and combination of internal and external fixation techniques, need to be deepened, which is of great significance for choosing a better fixation method and acquiring a better therapeutic effect.
