INTRODUCTION: Coronal plane distal humeral injuries are relatively rare. Numerous classification systems have been proposed as the complexity of these fractures has been realized. We in the present series of ten patients describe the surgical technique of Open Reduction and Internal Fixation of Coronal plane fractures of the distal humerus with headless compression screws performed using the anterolateral approach.

MATERIAL AND METHOD: It was a retrospective study, the data collected from March 2010 to 2015 was analysed and the final outcome was assessed using the DASH score. Out of a total of 13 patients with distal humerus coronal plane fractures, 10 patients were available for follow up. The X-rays and CT scans were reviewed and the fractures were classified according to Dubberley and Bryan and Morrey classification. Radiographic were evaluated for presence of union or nonunion, avascular necrosis, joint line step-off (none/1-mm/>1-mm), hardware failure and instability.

RESULTS: The average age was 41 years. The average DASH score in our study was around 24. The time to union ranged between 8-12 weeks with the average time being around 10 weeks. One patient had post traumatic Arthritis radiologically classified as Broberg and Morrey Type 2 and one patient had Heterotrophic ossification Brooker Grade 1.

CONCLUSION: Open reduction and internal fixation of coronal shear fractures of capitellum and trochlea using headless screw compression via the antero-lateral approach is a reliable treatment modality and results in stable fixation with restoration of a functional arc of motion.
