Introduction: Olecranon fractures represent 8-10% of all elbow fractures. The treatment goals for the olecranon fractures are restoration of elbow motion and prevention of stiffness and prevention of complications. Treatment of comminuted olecranon fractures with TBW and K-wires gives no stability to the construct and causes failure. So, plate fixation is commonly employed for comminuted fractures. Material and Method: In this retrospective study, we reviewed 12 patients who presented to our institute between July 2020 and March 2022, having olecranon fracture treated with open reduction and internal fixation with anatomical locking plate osteosynthesis. A 3.5 mm locking olecranon anatomical plate was used for definitive fracture fixation.On follow up visit at six weeks, three months, and six months (final follow up) after surgery, radiological and clinical evaluation was done. Results: Our study included 12 patients. Majority of patients were male (66.66%). According to Mayo classification system, maximum number of patients (50%) were Mayo type IIB. 3 patients (25%) were type IIIA and 2 patients were type IIIB. Mean interval period from injury to surgery was 18 hours. According to BrobergMorrey scale, out of total 12, 8 patients (66.66%) had excellent outcome, 3 patients (25%) had good outcome and 1 patient (8.33%) had fair outcome at 6 months. Conclusion: Displaced and comminuted olecranon fractures when treated with locking anatomical plate gives good to excellent functional outcome with less complications.
