The cause traced back to a severe elbow injury in his youth, one that gradually reshaped both bone and daily life. The joint fused, the structure weakened, and simple routines turned into daily negotiations. When he finally reached Vinmec, the challenge extended beyond surgery itself.
The Limits of the Elbow
Years of unsuccessful treatment slowly reshaped Phong’s expectations. Multiple surgeries offered little improvement, and the prospect of living with the deformity became increasingly real, until he reached Vinmec Times City International Hospital.
There, doctors determined that his condition represented an exceptionally complex post-traumatic sequel. “This is an extremely rare case with a very high level of complexity, and there are virtually no precedents in Vietnam,” said Dr. Tran Quyet, Head of Upper Limb Surgery, Musculoskeletal and Orthopedic Trauma Center, Vinmec Times City.
Time had taken more than movement from Phong’s elbow. In fact, it had stripped away much of its structure. The joint was completely fused and unstable, with an estimated six-centimeter defect in the distal humerus, leaving the left arm four to five centimeters shorter than the right.
That degree of damage placed the case beyond the reach of standard elbow replacement. Historically, megaprostheses were developed primarily for limb-salvage surgery in bone cancer. While their use has gradually expanded over time, its application at the elbow, particularly outside oncologic settings, continues to remain uncommon.
Phong’s condition fell into that demanding category, where conventional solutions had long since run out.
Engineering a Second Chance
After extensive multidisciplinary discussions, Vinmec’s medical team reached a decision shaped as much by responsibility as by expertise: a total elbow megaprosthesis combined with reconstruction of the extensive bone defect. For a patient who had already waited 27 years, there was little room for uncertainty.
The work began long before the day of surgery. Using in-hospital 3D technology, surgeons rebuilt Phong’s elbow virtually, layer by layer, studying what time had altered, anticipating what could be restored. CT-based models allowed the team to visualize the deformity in full, plan each step with care, and design a prosthesis tailored specifically to his anatomy. From that digital reconstruction, a patient-specific elbow joint was created using 3D printing.
Vinmec’s doctors created a bespoke elbow joint designed exclusively for Phong.
“The patient has waited for 27 years. Another failure would have had a severe psychological impact. That is why we were determined to create a new opportunity to change his life,” Dr. Quyet stated.
That preparation changed everything. The surgery was completed successfully, with no nerve or vascular injury recorded. Within three days, Phong was able to begin gentle movement of his arm. Two weeks later, he could extend and flex the elbow, lift his arm, and raise it overhead.
“After nearly 30 years, I finally feel like I have a normal arm again,” Phong said. “It moves so naturally, almost as if I never had surgery at all.”
Yet the most profound outcome was not measured in surgical time or range of motion. It emerged quietly, as a man who had learned to live within limitation began to reclaim independence, through ordinary actions.
Advancing Orthopedic Excellence
Such a miracle did not happen in an instant. It emerged gradually, shaped by a series of groundbreaking clinical achievements. In 2025, Vinmec carried out a personalized total femoral replacement using 3D-printed metal for a young child with aggressive bone cancer—preserving the limb in a case where amputation had been widely advised. Earlier, the system became the first hospital in Southeast Asia to successfully perform a fully 3D-printed titanium chest wall reconstruction.
These landmark procedures exemplify Vinmec’s patient-centered philosophy, where multidisciplinary expertise converges to confront the most complex conditions.
Stories like Phong’s extend far beyond Vietnam. They echo among patients worldwide, many of whom have been told that options are exhausted. At Vinmec International Healthcare System, growing clinical evidence shows that those paths are being created thoughtfully and deliberately.
