One of the goals of Hospital for Special Surgery (HSS) is to advance the science of orthopedic surgery, rheumatology, and related disciplines for the benefit of patients. Physicians at HSS may collaborate with outside companies for education, research and medical advances. HSS supports this collaboration in order to foster medical breakthroughs; however HSS also believes that these collaborations must be disclosed.
As part of the disclosure process, this website lists physician collaborations with outside companies if payments were received during the prior year, or if the HSS physician currently receives payment. The disclosures are provided by information provided by the physician and other sources and are updated regularly. Further information may be available on individual company websites.
Below are the healthcare industry relationships reported by Dr. Bauer as of August 07, 2017.
By disclosing the collaborations of HSS physicians with industry on this website, HSS and its physicians make this information available to their patients and the public, thus creating a transparent environment for those who are interested in this information. Further, HSS’ Conflicts of Interest Policy does not permit physicians to collect royalties on products developed by him/her that are used on patients at HSS.
Patients should feel free to ask their HSS physicians questions about these relationships.

Dr. Bauer’s main research focus has been to investigate mechanisms of success and failure of orthopedic reconstructive procedures, devices, and bone graft materials. He uses advanced microscopic and imaging methods to evaluate the biocompatibility of new materials, to document mechanisms of implant fixation or loosening, and to evaluate the consequences of device wear. He collaborates with surgeons, radiologists, and biomedical engineers to correlate observations made using new magnetic resonance imaging techniques, with intraoperative findings and the microscopic appearance of periprosthetic tissues. He also studies the optimum use of laboratory tests for the care of orthopaedic patients, and the diagnosis of periprosthetic infection. Most recently, he has validated the use of high-resolution digital scanning of whole microscope slides for diagnosis in surgical pathology.
