[E-learning via webinars in orthopedics and trauma surgery : Increase in supply and demand during the COVID-19 pandemic].

OU TO GO and BVOU Study Club already offered webinars prior to the COVID-19 pandemic. AO online Campus was designed in addition to the existing portfolio. The supply of WebDGU was newly established. Limitations of this study are the exclusion of commercial suppliers, non-German operating companies and all other types of e‑learning except webinars. The increased supply and demand for webinars during the COVID-19 pandemic gives hope for further improvement of e‑learning in the subject of orthopedics and trauma surgery.
