Hallux Valgus

Hallux Valgus

For orthopedic surgeon Tom Lootens we create a mixed reality application on the Microsoft HoloLens to assist the in the hallux valgus operation. By displaying digital scans of a patient's foot, he can determine where the incision must be made, without having to draw it out on paper or a screen. Next to that, he also uses application to educate the patient about the surgery in an immersive way.

What if we can assist the surgeon with AR?

How we did it.

First off, patients get access to The Hallux Valgus patient education app © AZ Maria Middelares. This app is used for educational purposes and provides patients with an AR experience. The projection shows patients how the surgeon will make an incision and perform a correction of the bone structure.

“By doing this we hope to create more transparency and trust towards our patients."

- Tom Lootens, head of orthopedics AZ Maria Middelares.

The Hololens is not only used by patients but also by surgeons. In the past, the surgeon had to draw the incision on a piece of paper. Now he can use the Hololens to display digital scans of the patient’s foot and determine where the incision has to be made, without having to look at a piece of paper or screen. Understandably, surgeons are optimistic about the use of mixed reality in the operating room.

In addition, experiments are being carried out to use the HoloLens professionally for the evaluation of possible cartilage injuries, caused by this inclined position. Cartilage covers joint surfaces and ensures smooth movement of the joint, without pain. By visualizing the affected cartilage with the HoloLens and treating it, the result of the intervention can be influenced in a favourable way. There is currently a study that will assess these effects. In the next phase, this project can be an incentive to use the HoloLens for evaluating other joints and injuries.
