The significance is great, take our country for example, a developing country with a huge population of 10 million patients with unfettered limbs alone, most of whom are disabled. Due to the lack of reconstructive surgery in the past, more than 3 million people have been amputated; the country has nearly 3 million bone defects and bone losses every year; and the trauma caused by car accidents and wars is even more countless. So, research into 3D-printed bones could benefit more defective human children.
What's more, 3D printing can also be used for medical diagnostics and surgical planning, and can make medical products, prototype equipment, biological models, anatomical models, or scaffolds for biological tissues. More powerful is immediately applied to the medical 3D printed organs, vertebrae, which can be a great benefit to all mankind, this research is very meaningful.
