Objective: Experience of Department of Oncologic and Degenerative Spine Surgery of Rizzoli Orthopaedic Institute during SARS-CoV-2 pandemic lockdown.

Patients And Methods: Retrospective observational study of surgically treated patients from 09th March 2020 to 04th May 2020.

Data Collected: age, sex, type of disease, neurological status, days of hospitalization, complications and type of discharge. A comparison analysis with same period of the last year was performed in order to evaluate the impact of COVID-19 spreading on daily surgical activity.

Results: A total of 107 surgical procedures in 102 patients were performed from 09th March 2020 to 04th May 2020. Analysis showed a statistically significant difference in age, sex, ASIA class and type of treated disease compared to the same period of the last year (p=0.042, 0.006, 0.022 and 0.007, respectively). No statistically significant differences were observed in type of discharge, length of hospitalization and complications (p= 0.447, 0.261 and 0.127, respectively). 3 COVID-19 infections have been identified in hospitalized patients. 1 COVID-19 patient wad admitted from Emergency Department and was managed according to a dedicated path.

Conclusions: Surgical activity was paradoxically increased during SARS-CoV-2 pandemic lockdown through the management of urgent and non-deferrable spinal disease with a low rate (3,9%) of COVID-19 infections.
