Mabrys team lining up the insertion handle for the socket using the mixed reality CT scan overlayScott Mabry, M.D.Scott Mabry, M.D., assistant professor in the Department of Orthopaedic Surgery, is utilizing mixed reality technology in total hip replacements.

Mabry uses this innovative approach during the placement of the acetabular component "socket." This process involves creating a 3D model of the patient's hip based on a CT scan, followed by a preoperative planning session to determine the ideal position for the hip replacement. During surgery, he wears a mixed reality headset, which enables him to overlay the 3D rendering of the patient's pelvis and surgical plan, ensuring precise placement of the implant as planned.

Mabry shared that patients who have undergone mixed reality total hip replacements have shown outcomes comparable to those undergoing traditional procedures, with notable improvements in weight-bearing capabilities for individuals with previous fractures.

Not only is the use of mixed reality transforming Mabry’s surgeries, but it is also transforming education in the Department of Orthopaedic Surgery.

In orthopaedic education, virtual reality can prepare surgeons for procedures. Instead of relying solely on reading technique guides and practicing on cadavers or sawbones, trainees can now immerse themselves in a virtual operating room.

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.
