Benefits of Poller Screw in Improving Radiological Outcomes after Intra-Medullary Nailing for Distal Tibia Fractures; A Retrospective Cohort Study.

Objectives: To compare the radiological outcomes after fixation of distal tibia fractures with IM nail between patients in whom poller screw was used vs those in whom it was not used.

Methods: A retrospective cohort study was conducted between 1st January 2009 to 31st June 2019 including patients treated with IM nail for distal tibial metaphyseal fractures. Patients were divided into 2 groups based on whether a poller screw was placed during surgery or not.
