The Vinmec Healthcare System, the leading private health system from Vietnam, has carried out a total femoral replacement (TFR) using a personalized 3D pressure metal for the youngest known patient, in which osteosarcoma was diagnosed. This not only saved the child's leg, it was a turning point for the role of Vietnam in high-tech precision medicine.
In 2022, aggressive bone cancer was diagnosed in 2022 after a minor injury to a young name Tran Minh Duc, which had penetrated into his entire femoral. The standard matters – amputation or bone transplant – issued serious risks, especially for a growing child.
Instead, Vinmec doctors suggested an unprecedented solution for the traditionally recognized approach in the country: to design and manufacture a custom femorine using 3D printing technology, which are precisely tailored to the anatomy of DUC. The implant was developed locally through cooperation between Vinmec surgeons and engineers from Vinuni, whereby CT and MRI scans completely model and produce the modular implant in Vietnam.
This two-phase operation included the removal of tumors and a temporary cement bone graft at the beginning of 2024, followed by a complete replacement by a 3D printed metal femur in May 2025. “We contacted foreign manufacturers, but there was no suitable design,” said Dr. Tran Duc Thanh. “Self -production of the equipment enables us to be proactively in treatment.”
The modular design of the implant enables future adjustments with the growth of DUC and embodies the principles of personalized and adaptable medicine. “The 4-hour operation was a success,” said Prof. Dr. Tran descend. “Duc has recovered quickly and he is now going with support.”
This case marks the first time that the 3D printing for TFR was used in such a young patient and was carried out with completely Vietnamese resources. In addition to the surgical success, it sets a new standard for how advanced production can change medical care in developing countries.
Vinmec continues to cross borders with 3D printing after he has previously achieved milestones such as creating a 3D printed chest wall and a simultaneous replacement for the Titan -3D breast wall and carried out a simultaneous pelvic and female replacement.
