Principle of artificial bone

Nano-artificial bone (NB series nano-crystalline collagen-based bone material) is a key project supported by the National "863" and "973". It is a new bone material invented by Professor Cui Fuzhai's research group on the hierarchical structure and biomineralization process of human bone callus and embryonic bone for many years. The biggest difference between it and the original traditional artificial bone material is that the repaired bone is exactly the same as the human bone, and no implant will be left in the body. It imitates the mechanism of human bone formation, and uses self-assembly method to prepare nano-crystalline hydroxyapatite or collagen composite biological hard tissue repair materials, so that the composite materials have nano-scale hierarchical structure of natural bone and porous structure of natural bone.

Generally, it takes several months for the "nano-artificial bone" implant to completely absorb it into the human body, and there is no immune or rejection reaction in the whole process. Moreover, the performance of this material makes it convenient for doctors to operate, which is comparable to other types of bone repair materials.

Besides being used for lumbar fixation and bone healing after lumbar spinal canal decompression surgery, nano-artificial bone has a wide range of applications, such as fractures caused by trauma, bone defects, bone disunion or abnormal healing caused by trauma and infection, bone diseases such as bone tumors, and even osteoporosis. Nano-artificial bone can be implanted to help heal and improve bone hardness.
