EFAS Lyon Congress 2021

EFAS aims to promote the development of foot and ankle surgery and to advance education, study, and research in this specialty.

EFAS will meet its goal of the advancement of the science and education in foot and ankle pathology, conservative and surgical treatment, offering practicing physicians, residents, and fellows instructional courses, seminars and symposia, international congresses as well as close collaboration and team learning programs to other medical and selected paramedical disciplines.

Here are some of the podium presentations and posters that featured WBCT Imaging at EFAS.
