Orthopedic infections

We work as infectious diseases consultants at the orthopedic University Hospital Balgrist Zürich. In a great collaboration with colleagues of internal medicine (Dr. med. J. Burkard and team), orthopedic surgeons (Prof. Dr. med. C. Gerber and his team), and microbiologists, we give advices for optimal antimicrobial treatment in patients with prosthetic joint infections and osteomyelitis. Through clinical collaboration, many scientific questions many questions arise, which we retrospectively and prospectively investigate. We make studies on epidemiology, pathogenesis, diagnostics, treatment and course of orthopedic infections.

In particular, we pursue the following specific aims:
Monitoring and improving the existing diagnosis of orthopedic infections. Evaluation of new diagnostic methods.
Retrospective and prospective analysis of applied treatments (antibiotics, surgical procedures) with focus on long-term course of the infection and detection of antibiotic side effects.
