Abstract：Objective To investigate postoperative ankle function recovery of patients with unilateral ankle fracture and its relationship with Danis-Weber classifications and morphology of the ankle mortise.Methods A retrospective study from June 2020 to January 2022 was conducted,including 82 patients with unilateral ankle fracture.All patients received X-ray and CT examinations of the ankle joint after admission to determine the Danis-Weber type of fracture and the morphology of ankle mortise.The patients were treated with open reduction and internal fixation for the ankle fracture.Mazur score of the ankle function 1 year after surgery was recorded.Multivariate logistic regression analysis was conducted to identify the risk factors influencing postoperative recovery of the ankle function.Results The postoperative Mazur score of the ankle function was excellent in 42 cases,good in 25 cases and fair in 15 cases.The proportion of Danis-Weber type A ankle fractures in patients with excellent ankle function was higher than that in patients with general ankle function;and the proportion of type C ankle fractures was lower than that in patients with general ankle function(66.67％vs.26.67％;4.76％vs.46.67％,P＜0.05).The difference values of ankle mortise height,ankle mortise width,ankle mortise depth,coronal angle and sagittal angle of patients with excellent ankle function[(0.28±0.04)mm,(0.84±0.21)mm,(1.56±0.40)mm,(2.37±0.60)° and(1.22±0.31)°]were lower than those of patients with good ankle function[(0.32±0.05)mm,(1.03±0.26)mm,(2.17±0.55)mm,(4.64±1.17)° and(2.45±0.62)°]and those with general ankle function[(0.40±0.08)mm,(2.75±0.69)mm,(3.89±0.98)mm,(5.80±1.46)° and(4.69±1.20)°](P＜0.05).Age ≥ 60 years(OR=2.815)and Danis-Weber type C(OR=3.053)were risk factors for poor postoperative recovery of the ankle function(P＜0.05).Conclusions The postoperative recovery of ankle function in patients with unilateral ankle fracture is closely related to Danis-Weber classifications and morphology of the ankle mortise.Older patients with Danis-Weber type C ankle fracture and abnormal morphology of the ankle mortise have a higher risk of poor ankle function recovery after operation.
