biomedical materials

Calcium phosphate, as the main inorganic component of bone tissue, can form chemical bonds with living tissue and has excellent bone conductivity and osteoinductivity. Bone is a hard tissue organ with life, and is the most important component of the human body. With the development of science and technology and the increasingly severe aging of the population, various types of trauma have increased sharply, and the demand for bone tissue replacement materials is constantly increasing. Calcium phosphate materials are very similar to the inorganic components in human bones in terms of chemical composition and biological properties. Therefore, they are widely used in bone tissue engineering and clinical medicine, and are a hot research topic for researchers in various countries.

Artificial bone

The physical and chemical structure of the artificially synthesized calcium phosphate ceramic repair material is similar to that of natural bone tissue. Its porous micro nano morphology and surface bioactive ions give it excellent bone conductivity and bone induction, which has broad application prospects in bone defect repair and treatment.

At present, commonly used artificial bone materials include calcium phosphate and calcium sulfate based artificial bones, bioactive glass, etc. Artificial bones mainly composed of calcium phosphate and combined with one or more other materials to improve the performance of artificial bones are currently a research hotspot.

bone cement

Calcium phosphate cement (CPC), also known as self curing calcium phosphate, can be arbitrarily plastic and self solidify under physiological conditions. Its hydration and solidification product is hydroxyapatite (HA), which is similar in composition to human bone minerals. It is a new type of hard tissue repair material and has been successfully used in clinical practice [8]. Calcium phosphate bone cement has good self fixation, easy formability, good biocompatibility, and bone conductivity, making it an excellent bone transplant material.

Treating fractures

The combination of external fixation bracket and local injection of calcium phosphate at the fracture end is a convenient and effective method for treating comminuted distal radius fractures. Not only is the fracture reduction satisfactory, but the fixation is indeed reliable, and early functional adjustment and training can be achieved
