3D-printed sternum implanted in Chinese woman

In a first such operation in the country, Chinese doctors have successfully implanted a 3D printed titanium alloy sternum into a 54-year-old woman to replace her tumour-affected breastbone.
The patient surnamed Gu has been recovering without complications since the surgery last month at Tangdu Hospital affiliated with the Fourth Military Medical University in Xi'an, capital of Shaanxi Province.
Gu, a retired worker in Luoyang City, Henan Province, was diagnosed with a sternum tumour last year.
The tumour was six to seven centimetres in diameter before the operation, said Wang Xiaoping, a senior thoracic surgeon with the hospital.
Wang said typically when the sternum is removed, a patient's heart will lose its protection, seriously affecting breathing and safety, Xinhua news agency reported.

Doctors spent half a month designing a sternum for Gu and asked a key laboratory at Northwestern Polytechnic University to print it using 3D technology.
Around the world, doctors have increasingly turned to 3D printing. Last month, the technology helped doctors in Shanghai separate three-month-old twin sisters who were conjoined at the hip.
