A seven week observational analysis of clinical activities in a North Italian orthopaedic hospital during the second wave of SARS-CoV-2 pandemic: far from usual volumes, but different from the first wave.

Activity levels are far from normality during the second COVID-19 wave. Elective surgery and outpatients-related activities are still strongly limited compared to 2019 while the number of urgent cases treated increased consistently. SARS-CoV-2 positive emergencies are slightly higher than during the first wave. These important changes are expected to impact on health service and hospital budget for long.
