Patient receives 3D-printed sternum and rib cage transplant

A partnership between CSIRO and Australian medical device company Anatomics has led to the first successful implantation of a 3D printed titanium and polymer sternal and rib cage in a New York patient.

Ms Penelope Heller, who was diagnosed with chondrosarcoma (a rare bone cancer) in 2014, had to have her cancer affected sternum removed.Her surgeon fashioned a replacement sternum and ribcage using off-the-shelf solutions and while the procedure effectively removed the cancer, ongoing pain and problems breathing made post-op life unpleasant.

A US patient has recieved a customised sternum and partial ribcage made from 3D printed titanium and combined with Anatomics’ ‘PoreStar’ technology

On 2 August 2017 the 20-year-old American underwent further surgery to replace her implant with a customised sternum and partial ribcage made from 3D printed titanium and combined with Anatomics’ ‘PoreStar’ technology, a unique porous polyethylene material providing “bone-like” architecture to facilitate tissue integration.

It is the first time this technology has been used in the United States and only the second time in the world that a 3D-printed composite sternum and ribcage has been implanted.

3D printing has significant advantages over traditional manufacturing methods, particularly for biomedical applications.

3D printing allows for advanced personalisation of implants so they uniquely fit their recipients, as well as rapid manufacture, which could mean the difference between life and death for a patient waiting for surgery.

CSIRO’s Director of Manufacturing Dr Keith McLean said the operation is the latest success story for the CSIRO-Anatomics partnership which began in 2014.

“I’m proud of our work with Anatomics that has enabled patients around the world to lead normal lives,” Dr McLean said.

The two parties produced the world’s first sternum and rib cage prosthetics for a cancer patient in Spain in 2015, and another for a British man who received the implant in 2016 after his sternum was removed following a rare disease.

The 2016 implantation marked another world first of a composite 3D printed titanium and polyethylene polymer prosthesis.

Anatomics Executive Chairman Dr Paul D’Urso said over the past 25 years there have been thousands of successful Anatomics’ implantations in patients in Europe, Australia and now the U.S.

“Anatomics technology is shaping the future of the prosthetics industry using improvements in scanning, design and fabrication technology,” Dr D’Urso said.

“Anatomics’ advanced capabilities in personalised healthcare have opened new doors for patients in need of implants that are customised for them rather than having to use mass produced ‘off-the-shelf’ devices that don’t fit as well,” he said.
