Brief Biography
Stephen B. Murphy MD is a surgeon, inventor and medical device developer who specializes in hip and knee reconstruction in Boston, Massachusetts. He is an Associate Professor at Tufts University School of Medicine. He majored in Engineering Sciences at Dartmouth College and received his MD from the Weill Cornell Medical College. He received his residency training at the Combined Harvard Orthopedic Residency program, completed two research fellowships in orthopedic biomechanics and the Maurice Muller Fellowship in Reconstructive Surgery at the Massachusetts General Hospital, the Brigham and Women’s Hospital, and in Switzerland.

As a medical student, Dr. Murphy became a leader in the development of three-dimensional orthopedic imaging and its clinical applications. In collaboration with Peter Kijewski PhD and Peter Walker PhD, he created among the first three-dimensional virtual and physical models of the hip and knee joints and designed the first custom artificial hip implants from patient-specific 3D modelling1. Beginning the following year during surgery internship, Dr. Murphy assisted visiting surgeon Paul Tessier, MD and the maxillofacial team at Children’s Hospital in Boston to provide 3D computer and physical modelling and planning of correction for maxillofacial deformities. Later during orthopedic residency, Dr. Murphy began developing software for the geometric analysis and correction of dysplastic hips, work that led to granting of the Frank Stinchfield Award from the Hip Society in 19902.

Following Chief Residency and Fellowship training with Michael Millis MD and John E. Hall MD at Children’s Hospital, Hugh Chandler MD at Massachusetts General Hospital, and Reinhold Ganz and Maurice E. Muller in Bern, Switzerland.

Clinically, Dr. Murphy is well-known for having invented and developed the superior approach to hip replacement7,8,9,10. Technologically, Dr. Murphy has been a leader in the development of computer-assisted orthopedic surgery technologies and is now most recognized for having invented4,5 and developed the HipXpert system. This personalized hip surgery system is likely the first web-based, rapid turnaround medical intervention technology, incorporating patient-specific hip surgery planning with reusable and universally adjustable smart mechanical navigation tools.

Dr. Murphy has received the Maurice E. Muller Award for Excellence in Computer-Assisted Orthopedic Surgery, awarded by the International Society for Computer Assisted Orthopedic Surgery and the John Charnley Award from the Hip Society as senior author on economic research.
