3D Printing Used to Make Synthetic Bones for Grafts 2018-07-0936232




Hey, Lucy.How are you?Orthopedic surgeon Nirav Shah specializes in shoulders and knees.He replaced Lucy Pelagian’s shoulder three months ago, one titanium joint later, she’s doing well,but what if he could have ordered up a 3D printed shoulder customized to her measurements.What Ramona and Adam have done is they’ve created something very, very unique, very, very innovative and a game changer in many aspects.In essence, they’ve created a synthetic bone if you would.
嘿,露西。最近怎么样?整形外科医生Nirav Shah专事研究肩膀和膝盖。三个月前,他帮助Lucy Pelagians移植了肩膀,是一个钛合金关节,后来她活动得很不错,但是如果根据她的尺寸用3D打印机打印一个肩膀会怎么样呢?Ramona和Adam创造了非常非常独特、非常非常创新的东西,在很多方面而言,他们改变了游戏规则。本质上讲,如果你愿意的话,他们可以合成骨骼。
Ramona is Dr. Shah’s wife and a material scientist at Northwestern University.With support from the National Science Foundation,she and engineer Adam Jacobs have developed a new 3D printed synthetic material called hyper elastic bone.What 3D printing allows us to do also is to make patients specific or patient matched implants where if a patient comes in with a defect say a craniofacial defect,we’re able to take a scan of that defect and print it into the right size and shape that fits that patient perfectly.Unlike a bone graft from a patient’s own body or from metal or traditional ceramic,
Ramona是Shah博士的妻子,是西北大学的一名材料科学家。在国家科学基金会的支持下,她和工程师Adam Jacobs开发了一种新的3D打印合成材料,称为超弹性骨。3D打印能够做出特定的或者和病患匹配的移植物,如果患者患有颅面缺陷,我们能够扫描该缺陷并将以正确的尺寸和完美贴合患者的形状将其打印出来。与患者自身或金属或传统陶瓷的骨移植不同,
the new synthetic bone is made of an elastic ceramic, so if it’s squished it bounces back to its original shape.It starts as a liquid ink and is printed out in whatever shape the doctors need.The process is fast and everything happens at room temperature.It deposits on a surface and wherever we put the material, it goes where we want it to go.They also print sheets.So with the flat sheets we are able to create off-the-shelf products where the surgeon can take these sheets and cut it down to size,they can be rolled as well it can be sutured and be folded.
Once implanted the hyper-elastic bone promotes tissue growth and it becomes part of the patient’s own bone as it regenerates.So once implanted inside the body, the hyper-elastic bone eventually becomes new bone. It becomes part of you.The new synthetic bone is less expensive than what’s been available up until now and it handles better in the operating room.Dr. Shah says surgeons are ready to embrace this advance and its implications for improving patient outcomes.
