UConn Health is training orthopaedic surgery residents using VR solutions from PrecisionOS™ and Oculus

How UConn Health and PrecisionOS are training orthopaedic surgery residents using Oculus Quest headsets.

According to Dr. Augustus Mazzocca, who helps train residents in orthopaedic surgery as the Director of the Musculoskeletal Institute at UConn Health, not every surgeon is a natural. “As in any profession, some people are not as naturally gifted, so we make up for that by doing volume,” he says. “If a resident is struggling, we have them do as many cases with variability and obtain as many repetitions in the area that they are weak until they eventually obtain the skill.”

Multiple factors have led to the development of creative methods to surgically train orthopaedic residents outside the actual operating room. At UConn Health, residents practice their skills on cadavers in the Bioskills Laboratory. But practice procedures are expensive and time-consuming, and residents can only complete certain procedures on cadavers once.

Using virtual reality to enable purposeful practice.

In 2019, the UConn Orthopaedic Department discovered PrecisionOS, a medical software company that offers interactive VR experiences for surgical training in orthopaedics. Founded by Dr. Danny Goel, an orthopaedic surgeon and educator, and Rob Oliveira and Colin O’Connor, two veteran game developers, PrecisionOS offers medical-grade VR training and educational modules that enable surgeons to practice orthopaedic procedures in a safe environment and at a relatively low cost using Oculus Quest headsets.

Dr. Goel says his team wants to make teaching and learning with VR as valuable and real-world as possible in a safe, low-risk environment. “We’re pushing the boundaries of simulation during the operative experience in virtual reality,” he says. “The Oculus Quest headset was a game-changer for us. It’s mobile and offers high-quality haptics, six degrees of freedom, and high-fidelity visuals. This allows doctors to get in and get started fast.”


Dr. Mazzocca was skeptical of VR until the moment he put on an Oculus Quest headset. “It’s insane how quickly your body adjusts — I couldn’t believe it,” he says. “Easily within a minute, you become part of that environment. And the quality of work in the PrecisionOS system is incredibly similar to the real world.”

For UConn Health, VR with PrecisionOS and Oculus Quest headsets represents a breakthrough because it allows residents to engage in purposeful practice — identifying the skills they need to work on and practicing those skills repeatedly. It also delivers a double-loop learning system that lets residents make mistakes and gives them feedback to incorporate on their next try.

“The magic part for us is that we can go over an entire case multiple times,” Mazzocca says. “I can connect via computer and see what the residents are seeing — I become their eyes. I can see how quickly they’re looking at things, what they’re looking at, and how they’re reacting to various situations.”

When residents are putting a pin in a bone in VR, they can hone their 3D spatial awareness as they learn how to reduce the fracture, position the X-ray to get the appropriate view, and place the pin in the perfect position. “These are all critical skills they have to learn, perfect, and master so they can proceed with cases in a much more efficient and reproducible way,” Mazzocca says.

Keeping medical training moving forward during the COVID-19 outbreak.

A few months into 2020, UConn Health suspended elective surgeries due to COVID-19. While this has further reduced real-life training opportunities for residents, the team is grateful that residents have been able to keep their skills going and keep practicing thanks to VR.

Looking to the future.

Dr. Mazzocca believes VR will have a far-reaching impact on patient outcomes in the field of orthopaedics. “It makes unbelievable sense that surgeons will soon be able to load CT scans into VR and see where a deformity is in a damaged or diseased joint, see how to reduce a fracture, and find out where problems are going to arise before a case even happens.” He also believes that VR will help improve surgical training in areas of the world that don’t allow the use of cadavers in education.

“Globally,” he says, “we haven’t even scratched the surface of what this technology can do.”
