Introduction: Trimalleolar fractures are one of the complex fractures in the ankle joint involving lateral, medial and posterior malleolus often resulting from high energy trauma. These fractures usually require prompt surgical reduction and internal fixation. Surgical intervention is commonly indicated to restore anatomical alignment and good functional outcome to prevent long term complications.

Objectives: To evaluate functional outcome of surgically treated trimalleolar fractures by specific modalities and the complications involved in a study of 33 patients.

Materials and Methods: This study comprised of 33 patients with trimalleolar fractures treated surgically from November 2022 to November 2024. The patients underwent open reduction and internal fixation using plates and screws. Preoperative and postoperative clinical evaluations were performed along with radiographs. Functional outcome was assessed using Olerud and Molander ankle score with a follow up period of minimum 2 years.

Results: In this study of 33 patients with trimalleolar fractures treated by open reduction and internal fixation, excellent results were observed in 20(60.6%), good in 6(18.1%), fair in 5(15.1%) and poor in 2(6.06%). The common complications observed were persistent swelling, residual pain and surgical site infection in postoperative period.
