In a series of 146 displaced ankle fractures, the effects of age, sex, side of injury, mechanism of injury, severity as determined by the Lauge-Hansen classification, type of injury (open or closed), open or closed treatment, and internal fixation of one or both malleoli were analyzed using subjective, objective, and radiographic parameters. Statistically significant prognostic features were identified and a prognostic scale was developed using multiple linear-regression analysis. The significant parameters were age, adequacy of the post-reduction positions of the medial and lateral malleoli, and completeness of the restoration of the deltoid ligament and distal tibiofibular syndesmosis. Open reduction proved superior to closed reduction, and in bimalleolar fractures open reduction of both malleoli was better than fixing only the medial side. Using the data on the first 109 fractures, a multiple linear-regression equation was formulated and used to predict the outcomes of the last thirty-seven fractures in the study. The accuracy of the predictions in them was 81 per cent.
在一组146例移位性踝关节骨折中，采用主观、客观和影像学参数，分析了年龄、性别、受伤侧别、损伤机制、Lauge-Hansen分类法确定的严重程度、损伤类型（开放性或闭合性）、开放或闭合治疗以及单踝或双踝内固定的影响。确定了具有统计学意义的预后特征，并使用多元线性回归分析制定了预后量表。显著参数包括年龄、内外踝复位后位置的适当性以及三角韧带和胫腓下联合复位的完整性。切开复位证明优于闭合复位，在双踝骨折中，双踝切开复位优于仅固定内侧。利用前109例骨折的数据，建立了多元线性回归方程，并用于预测研究中最后37例骨折的结果。其中预测的准确率为81%。
