University of Alabama at Birmingham Brings VR Headsets to Operating Rooms

Virtual reality headsets are known for being used by kids or video game fanatics to explore new virtual worlds. However, experts at the University of Alabama at Birmingham have brought these VR headsets into the operating room and skills lab.

Scott Mabry, M.D., assistant professor in the UAB Department of Orthopaedic Surgery, is using mixed reality technology to help perform and teach total hip replacements, specifically the replacement of the acetabular component socket.

First, he creates a 3D model of the patient’s hip based on a CT scan. He then conducts a preoperative planning session to determine the ideal position for the hip replacement. During the surgery, Mabry wears a mixed reality headset, which enables him to overlay the 3D rendering of the patient’s pelvis and surgical plan. This helps ensure precise placement of the implant.

“While this technology can be used in any hip replacement, I have found it most beneficial in patients with complex or unusual anatomy,” Mabry said. “In these situations, you cannot use your normal landmarks in surgery, so the mixed reality helps to overcome that barrier.”

The use of mixed reality is transforming Mabry’s surgeries, while transforming education in the Department of Orthopaedic Surgery. Instead of surgeons relying solely on reading technique guides and practicing on cadavers, trainees can immerse themselves in a virtual operating room.

“With the implementation of virtual reality, you may now enter a virtual operating room and simulate a surgery using a new technique or implant,” Mabry said. “This is helpful to build familiarity with the steps of the procedure and muscle memory.”

Mabry envisions this adaptive simulation model will contribute to the development of highly skilled and confident medical professionals, better equipping them to handle real-world challenges.
