[Clinical Value of Minimally Invasive Bridging for the Lateral Malleolar Fractures in the Open Comminuted Ankle Fractures with Dislocation].

To evaluate the effectiveness of minimally invasive bridging for the lateral malleolar fractures in the open comminuted ankle fractures with dislocation. Methods The clinical data of 24 patients [19 males and 5 females aged 40 to 65 years,mean(47.5±8.6)years] with open comminuted ankle fractures with dislocation who were treated in the Second Hospital of Tangshan from September 2015 to June 2017 were retrospectively analyzed.All patients were treated with minimally invasive bridging for the lateral malleolar fractures.The ankle function after treatment was assessed with the Olerud Molander Ankle(OMA)score. Results All the 24 patients were followed up from 12-26 months [mean:(14.5±2.6)months].Good fracture union was achieved in all patients after 2 - 5 months(mean:3 months).No deep infection,skin necrosis,or bone nonunion occurred after 12 months of follow-up.Only one patient suffered from partial skin necrosis at lateral malleolus,which was cured after changing wound dressings.The OMA score was 93.5(range:85-100)after 12 months(excellent in 19 cases and good in 5 cases). Conclusions Minimally invasive bridging for the lateral malleolar fractures is effective in treating the open comminuted ankle fractures with dislocation.It can obtain good reduction and fixation,reduce complications,and achieve high union rate.
