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.
