The treating doctor will be asked to complete a questionnaire on other risk factors. This will include details of the mechanism of injury, whether the injury was open or closed (and the Gustillo grade of an open injury), other injuries the participant has sustained, and the treatment received for their injuries, as well as the patients' insurance status. The definitive treatment for the tibia fracture will be classified as either external fixation with casts (plater of paris or fibreglass), intramedullary nailing, internal fixation with plates and screws, or external fixation.
