Sydney University researchers make bone cement 3D printing breakthrough

Researchers at University of Sydney have developed a technique for bone replacements using 3D printing that could revolutionise surgery for head trauma victims.

The ABC’s AM program reports that cranioplasty implants can take weeks to make, and can cost thousands due to the materials used (such as titanium).

The university’s Dr Philip Boughton, a biomedical engineer, has developed a 3D printing technique using “bone cement” and modelling using a patient’s CT scans. This takes only days and about $300.

“We're helping to address what can often be an emergency situation as close to the day when the patient comes in as possible. Implants are going to be, starting to be patient specific,” Boughton told the ABC.

“Rather than fitting the patients to the implant, we're basically taking the patient's scans and customising the implant able to the patient.”

The replacement portions of skull have been used to treat injuries ranging in size from a “twenty cent piece to missing about 40 per cent of the skull,” said Jeremy Kwarcinski, a PhD student at the university.
