Surgery: virtual reality as a back-up

Article written by

Mixed reality, which makes it possible, thanks to 3D images, to compare a simulation with a real surgical act, is today a precious tool for doctors. In Nice, an orthopedic surgeon has just tested the technique for the first time.

This is not a first in France, but for Marc-Olivier Gauci, it is a baptism of fire. At the Pasteur hospital in Nice, this orthopedic surgeon is the first to test mixed reality during an operation. Already experienced in other establishments includingTours hospital, this technique allows the holographic simulation of an operation to be superimposed on the actual surgical act.

On the operating table, a 65-year-old woman who suffers from osteoarthritis in the shoulder and to whom the surgeon is going to implant a prosthesis. A procedure that the doctor carefully prepared beforehand. Using a 3D model of the patient’s shoulder from a CT scan, he can study the joint from all angles and determine the best way to operate. These images are then projected in the form of a hologram in the surgeon’s virtual glasses, allowing him to compare the simulation with the reality of the operation.

This technology, which combines virtual and augmented realities, makes it possible to optimize surgical procedures and thus avoid complications. Each year in France, 18,000 patients have a shoulder prosthesis implanted.
