Description
Mayank Tripathi and coauthors published a 2026 surgical report of a custom 3D-printed titanium breastbone and rib implant after near-total breastbone removal. The patient, a 28-year-old man, had a giant cell tumor of the sternum. Large removals endanger the chest wall's rigidity and leave the heart exposed, while standard reconstructions sacrifice anatomical fit.
The workflow ran from CT scans through virtual resection planning, computer design with rib-coupling flanges and soft tissue eyelets, a plastic rehearsal model, and metal printing. The implant was fixed to a sliver of remaining upper sternum, the lower remnant, and rib stumps in one operation. Double-layer mesh and preserved chest muscle closed the wound without a skin flap. The authors document the full blueprint alongside the intermediate outcome.
