3D printing employed to help patient with tumor
Print Edition
Doctors have implanted a 3D printed titanium alloy sternum into a woman to replace her tumor-affected breastbone, the first such operation in China.
The 54-year-old patient, surnamed Gu, is said to be recovering well at Tangdu Hospital in Xi鈥檃n, capital of northwest China鈥檚 Shaanxi Province.
The tumor was 6 to 7 centimeters in diameter, said Wang Xiaoping, a senior thoracic surgeon at the hospital.
Typically, when the sternum is removed, a patient鈥檚 heart loses its protection, seriously affecting breathing and safety, Wang said.
Doctors designed a sternum for Gu and asked a laboratory at the Northwestern Polytechnical University in Xi鈥檃n to print it using 3D technology.
Last month, the technology helped doctors in Shanghai separate 3-month-old twin sisters who were conjoined at the hip.
Dr Zheng Shan, vice president of the Children鈥檚 Hospital of Fudan University, said 3D printing technology was used to identify the twin鈥檚 spine, bone and hip structure.
The technology gave the doctors a clear view of the conjoined parts and helped ensure the accuracy of the cut and protect the nerve system.
