【Abstract】 Objective To investigate the efficacy of fracturedislocation of talus by external fixation combined with Kirschner wire and provide a theoretical basis for surgical treatment of fracturedislocation of talus. Methods In this study, 24 patients with fracturedislocation of talus treated in our hospital from June 2015 to June 2016 were enrolled. Among them, 4 cases had the complication of medial malleolar fracture, 3 cases had lateral malleolar fracture, 5 cases suffered from calcaneus fracture, and 12 cases had fracturedislocation of talus. The fracture condition was clarified by the Xray examination. All patients underwent one stage debridement and reduction, then received external fixation combined with Kirschner wire on the treatment of open talus fractures after the use of combined spinal and epidural anesthesia. In the postoperative 18~32 months followup, the functional results were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) at the post 6mon and 18mon. Then a comprehensive evaluation of surgical effect was made at the post 18mon. The postoperative complications were recorded. Results The average duration of followup was (1823 ± 323) months. The result was excellent in 10 cases, good in 8 cases, fair in 4 cases and 2 cases in poor, and the overall excellent or good rate was 7500%. The AOFAS score was (7545 ± 467) at post 6mon and was (8734 ± 511) at post 18mon, with a statistic difference (P＜005). Postoperative traumatic arthritis was found in 1 cases, incision infection in 2 cases, chronic ankle pain in 2 cases, and ischemic necrosis of talus in 2 cases. Conclusion The external fixation combined with Kirschner wire is effective in fracturedislocation of talus, which can ameliorate the ankle joint function, however, the strict attentions should be paid on the postoperative complications, such as incision infection and ischemic necrosis.
