The surgical technique for each patient managed operatively, in both the observational and randomised arms of the study, will include fixation using a plate and screws. Any adverse intra-operative or post-operative event will be recorded. This includes but is not limited to death, infection, VTE and neurovascular injury. Post-operatively, all patients will be non weight bearing and placed in a below-knee plaster cast or walking boot. Discharge from hospital will be determined by the patient's ability to walk 25 m unaided by standby assistance as determined by a physiotherapist. The treating surgeon will review the patient after 10-14 days for assessment of the wound, removal of sutures and change of cast to a fibreglass cast or walking boot (cam walker). The patient will then be allowed to WBAT (weight bearing as tolerated) for a further 4 weeks. This protocol represents usual post-operative practice for this injury, as determined through meetings with the Australian Orthopaedic Trauma Society.
