SARS-CoV-2 / COVID 19 is the largest health emergency and a global pandemic of recent times. Orthopaedic surgery involves procedures involving routine reaming and drilling the bones that generate substantially high volumes of aerosols and microdroplets creating a huge concern among the operating surgeons, anaesthetists and the supporting staff. We aimed at reducing the amount of aerosol generation and microdroplet spread by a simple and cost-effective technique which can be very well reproducible by anyone, thereby reducing the infection/viral load.
