[Objective]To evaluate the clinical efficacy of modified hybrid external fixator for tibiofibular metaphyseal fractures com-plicated with severe soft tissue injury in the elderly.[Methods]A retrospective study was performed on 27 patients who aged of(68.4±4.5)years,and had tibiofibular metaphyseal fractures complicated with severe soft tissue injury was treated with improved hybrid external fix-ators as a full treatment from May 2020 to April 2023.The documents regarding to treatment period and follow-up were evaluated.[Re-sults]All patients received the treatment successfully and had the wound healed satisfactorily.The fracture reduction on imaging was marked as excellent in 17 cases(63.0％),good in 10 cases(37.0％),and poor in 0 cases.The patients had hospital stay of(7.4±2.4)days,and time to get partial weight-bearing of(19.7±4.5)days.The VAS score decreased significantly with time before surgery,3 days after sur-gery,and 1 month postoperatively[(7.1±1.4),(3.7±1.3),(1.1±1.3),P＜0.001].All the patients were followed up for(24.0±6.4)months,and 5 patients(18.5％)of them developed pin tract infection,which didn't lead adverse consequences.In addition,2 patients suffered from de-layed union of the fracture were given local bone grafting with the original external fixator in place.Finally,all the 27 patients got the frac-tures healed well at the last follow-up,with low extremity functional score(LEFS)significantly increased over time 3,6 and 12 months postoperatively[(36.7±9.7),(60.1±4.1),(75.9±2.9),P＜0.001].[Conclusion]The modified hybrid external fixator is a safe and effective tech-nique for the treatment of tibiofibular fractures complicated with severe soft tissue injury in the elderly.
