VinUni won second prize in the 2023 Science Innovation Competition

Personalized surgical guidance (PSI) can guide the surgical position of joint replacement with up to 98% accuracy. Surgeons will rely on PSI to perform bone cuts during surgery according to the programming plan, helping to increase the accuracy of the artificial joint placement position to optimize the effectiveness and safety of surgery for patients. In Vietnam, there has never been any research on the application of PSI in joint replacement surgery.

The research team successfully performed nearly 50 total knee replacements as well as 40 hip replacements and hundreds of other joint replacements and bone alignment cases using 3D printing technology for personalized surgical guidance devices at the Vinmec healthcare system.

In addition to products applying 3D technology in orthopedic trauma (PSI, patient's bone and joint anatomical model), this technology is currently also applied to other products in the field of creating nasal molds for children with cleft palate, anatomical models to help personalize interventional stents for complex cardiovascular cases or 3D titanium patch molds for skull bone defects.

VinUni won second prize in the 2023 Science Innovation Competition - 1 — MD.CKII Pham Trung Hieu received the award.

BSCKII Pham Trung Hieu - representative of the 3D LAB VINUNI research group shared that currently, to perform surgeries to treat and reconstruct damaged bone and joint structures, it is impossible without navigation aids that require high precision.

Because the skeletal system is a complex dynamic balance system in 3D space, placing the artificial joint in an incorrect optimal position can lead to changes in the body's axis of motion, affecting post-operative mobility, as well as causing prolonged local pain or reducing the lifespan of the artificial joint in the body.

In addition, artificial joints and accompanying guidance devices are currently imported and designed to fit the European and American body, which is not compatible with the bone structure of Vietnamese people, which can affect the exact placement of the implant devices, reduce the effectiveness of treatment, and can even lead to complications if the surgeon is not experienced.

" This is the reason why the team developed the idea of a personalized surgical guidance device printed with biocompatible 3D materials that can safely contact the patient's tissue, while achieving higher precision, safety, and convenience in surgery than currently available devices, while having an acceptable production cost ," said Dr. Hieu.

VinUni won second prize in the 2023 Science Innovation Competition - 2 — VinUni research team.

According to Prof. Dr. Tran Trung Dung, Director of the Center for Orthopedics and Sports Medicine, Vinmec Healthcare System, personalized treatment in medicine is a world trend, in which the development of surgical guidance devices will contribute to optimizing surgical efficiency.

Previously, an experienced surgeon could achieve the desired maximum surgical accuracy of around 90%, but with surgical guidance devices the accuracy can approach 98%.

" The navigation technology is like a 'scope' that can help improve accuracy, playing an important role in increasing the success rate of surgery, " said Professor Dung.

After receiving the award, representative of the Center for 3D Technology in Medicine - VinUniversity, BSCKII Pham Trung Hieu shared: “ In Vietnam, there has never been any research on the application of PSI in joint replacement surgery. We hope that 3D printing technology to create personalized cutting molds can be applied to mass production suitable for the characteristics of Vietnamese people.

We are moved, happy and proud to be able to bring opportunities to many patients, and bring advanced technology in the world to serve the Vietnamese people ."

According to experts, the new solution has a cost not too different from the old open surgery methods, even lower; and can be applied to other products.

In addition, the application of 3D technology to print personalized cutting molds not only saves a lot of time to complete cutting molds (on average 3 days, the earliest is 2 days, instead of 1 - 3 weeks as usual), but also demonstrates superiority in accuracy.

The Science Initiative Competition is held annually under the direction of the Ministry of Science and Technology as a playground for those who love science and technology. In 2023, the competition attracted more than 130 projects and research works from scientists, young researchers and students from schools and universities across the country after only two months of launching.
