Tissue reactions of porous biphasic calcium phosphate ceramic in posterior spinal fusion;

Objective:Biphasic calcium phosphate nanocomposite (NanoBCP) is a kind of new scaffold which have a porous and 3D structure.

It has been deeply believed that the formation of the bone-like apatite containing carbonate in the calcium phosphate ceramics is important to the growth of the new bone and the osteoinductivity of the materials.

At present, many researches have been carried out to study the calcium phosphate ceramics without carbonate.

To explore a novel diphase Ca-P scaffold material which had good bioactivity and long-term osteogenesis,a pure HA scaffold coated with diphase calcium phosphate ceramics film was prepared by sol-gel method.
