Introduction

Management of a patient with a neck of femur (NOF) fracture is a key aspect of orthopaedic trauma care, with around 75 000 new cases in the United Kingdom annually costing the health care over £ 2 billion. Delaying time to theatre for operative intervention of hip fractures negatively impacts on patient outcome and is one of the key aspects of the hip fracture best practice tariff (BPT). One aspect of the peri-operative management of patients with hip fractures implicated in delayed surgery is the use of long term warfarin for anticoagulation. Anticoagulation reversal is a common cause of operative delay.
