Into hospital in Rio implements 3D printed prosthetics

The National Institute of Traumatology and Orthopedics (Into) in Rio de Janeiro has begun producing customized prosthetics using 3D printing technology for patients within the Unified Health System (SUS). These additive manufacturing laboratory products are lighter, more durable, and more cost-effective than traditional options. The facility is also preparing to implement orthopedic robotic surgery, which will eventually be integrated with advanced orthobiological therapies.

Operational data shows a significant increase in activity, with hospitalizations rising by 44% and surgeries by 38% compared to 2025. Surgical throughput has tripled, reaching an average of 1,100 operations per month. This modernization is supported by a R$ 2.4 billion investment from the Ministry of Health in Rio de Janeiro hospitals, managed through a partnership involving Fiocruz, the City of Rio, and the Conceição Hospital Group.

As hospitals adopt these personalized 3D-printed medical devices, maintaining strict traceability is critical. Ensuring that a customized implant matches the correct patient requires rigorous digital tracking—from medical imaging and segmentation to file version control and manufacturing parameters—to prevent errors in the highly regulated medical workflow.
