External Professional Relationships

A University of Maryland Department of Orthopedics faculty member may have external professional relationships with health-care related businesses. These relationships often lead to the development of new treatments and therapies. The Department of Orthopedics believes that transparency and honesty in the reporting of these relationships is essential to maintaining trust with our patients and mitigating any conflicts of interest or perceived conflicts that may arise.

For faculty who earn royalties on the sale of medical devices, no royalties are earned on any devices sold to patients or to hospitals that are part of the University of Maryland Medical System or in any other facilities where those faculty members treat patients.

All external professional relationships maintained by members of the University of Maryland Department of Orthopedics are reviewed and approved in advance by the Dean of the University of Maryland School of Medicine (UM SOM) for conformance with UM SOM policies in regarding conflicts of interest, conflicts of commitment, and professionalism.
