Objective: The purpose of the study was to investigate the therapeutic efficacy and application value of Llizarov external fixator in the treatment of type II Pilon fracture. 

Methods: A total of 100 patients with type II Pilon fracture admitted to the orthopaedics department of our hospital from February 2017 to June 2019 were selected and their clinical data were retrospectively analyzed, and according to different surgical methods the patients were divided into 2 groups, group A and group B, with 50 patients in each group. Among them, group A patients received Llizarov external fixator, while group B patients were treated with delayed open reduction and internal fixation. After that, operation duration, intraoperative blood loss, the incidence of adverse reactions, ankle pain score, ankle activity score as well as the recovery of fracture sites of the patients were compared between the two groups, so as to analyze the clinical significance of the Llizarov external fixator. 

Results: The operation duration and intraoperative blood loss of the patients in group A were significantly lower than those in group B, with statistical significance (P<0.05); the incidence of adverse reactions of the patients in group A was significantly lower than that in group B, with statistical significance (P<0.05); the ankle pain score and ankle activity score of the patients in group A were significantly higher than those in group B, with statistical significance (P<0.05); the recovery of fracture sites of the patients in group A was significantly better than that in group B, with statistical significance (P<0.05). 

Conclusion: Treatment with Llizarov external fixator can significantly reduce operation duration, intraoperative blood loss and the incidence of adverse reactions, improve ankle function and promote the recovery of fracture sites in patients with type II Pilon fracture; therefore the Llizarov external fixator has high application value in the treatment of type II Pilon fracture.
