Once the stuff of science fiction movies, computer assisted surgery is now commonplace in operating theatres around the world. One of the leaders in the field, Queen’s University professor Randy Ellis was recently honoured with Maurice E. Müller Award, a lifetime achievement award from the International Society for Computer Assisted Orthopaedic Surgery.

For the past 19 years, Dr. Ellis (School of Computing, Surgery and Mechanical and Materials Engineering) has dedicated his career to computer assisted surgery and helping surgeons successfully complete difficult surgeries.

Randy Ellis demonstrates how computer assisted surgery works.

“Contributing to society is important,” says Dr. Ellis, who started his career in the field of robotics and now works out of the Queen’s , “and this award is recognition from my peers for a successful career.”

In 1994, Dr. Ellis went to Italy to study surgery and a year later he joined forces with Queen’s professor John Rudan (Surgery) to develop software to perform the first computer assisted orthopedic surgery.

“Using computer assisted surgery, surgeons can accurately predict the result of the surgery. The technology also makes a difficult surgery possible, which increases the chances of a successful surgery,” he says.

Dr. Ellis is continuing his research into learning how joints move to create even more accurate computer programs for surgery. Currently, he is focusing on poorly healed fractures and early onset arthritis.

“I am revisiting how the human hip moves,” he explains. “I’m fascinated with the human hip because it’s vastly underappreciated. I want to maximize the potential of the hip and help people suffering from arthritis.”
