Introduction: Of all the lower limb fractures ankle fractures are one of the most common accounting for almost 9% with the annual incidence being 107-187 per 1 lakh population. Treatment of this fracture is complicated and challenging as the outcome will influence the locomotive power. Improper and inadequate fixation can cause long term disability as body weight is transmitted through it. Aim of study: To assess the functional and radiological outcome of displaced bimalleolar ankle fractures and to assess the rate of complications. Materials and Methods: This prospective study was done at the Department of orthopaedics in K.R. Hospital, Mysuru after obtaining informed consent from patients. A total of 50 patients between the age of 18-50 years were treated with Open Reduction and Internal Fixation with various methods for bimalleolar fracture between August 2017-January 2018; These patients were followed for 12 months and evaluated based on union rate, complications (Infections, Nonunion) and functionally by Baird and Jackson ankle scoring system. Results: In our study of 50 patients, bimalleolar ankle fractures treated by ORIF by various methods were followed up for 12 months. In our study, majority were males (72%). Mean age group included in the study was 33 years. In majority of patients, the mode of injury was RTA (72%) and most common fracture type being AO Type 44 A (56%). As per Baird and Jackson scoring system excellent to good functional outcome was seen in 78.3% individuals with fair outcome in 17.9% and poor outcome in 5.6%. Complications were seen in 9 patients and only two underwent re surgery for non-union. Conclusion:We found that ORIF yielded good results in terms of anatomical reduction, stability and post-operative functional outcome. Hence as per our study we can safely conclude that open reduction and internal fixation should be the treatment of choice for all unstable ankle fractures.
