Vinmec hospitals in Vietnam introduced a patient-specific 3D-printed elbow megaprosthesis to restore arm function for a man who had lived with a fused, shortened elbow for 27 years. The surgical team reconstructed his anatomy from CT scans, featuring a digitally modeled implant designed to replace missing bone and recreate joint mechanics. The operation was presented as a domestic first for this type of complex, non-oncologic elbow reconstruction.
Surgeons used CT-based virtual planning on an in-house platform to map the defect, simulate the reconstruction and produce a bespoke megaprosthesis via additive manufacturing. Vinmec did not disclose the printer or implant material because of partnership agreements, but reported no nerve or vascular complications and rapid early mobility.
For patients with long-standing trauma or large bone loss, bespoke megaprostheses can convert previously untreatable cases into functional limbs, illustrating how digital planning plus 3D printing expands reconstructive options and regional clinical capability.
