Traumatism in the country and in the world does not fall and even grows, and often it is bone fractures. Although bone tissue is able to regenerate, there are times when bone grafting is required. There are many requirements for the materials used for these purposes. They must be biocompatible, initiate the process of bone tissue regeneration, serve as a matrix for the formation of new bone, and have mechanical properties similar to those of bone.
For biomedical purposes, biodegradable (biodegradable) polymers of hydroxy derivatives of alkanoic acids, or, as they are called, polyhydroxyalkanoates (PHA), are promising. The class of these compounds includes more than a hundred types of polymers, but the most studied and widespread is poly-3-hydroxibutyrate - P (3) GB. This compound is formed during metabolic processes in the cells and tissues of higher animals and humans, due to which it has good biocompatibility and at the same time is biodegradable. Moreover, biodegradation occurs slowly, so that the polymer has time to fulfill the function of a matrix and stimulator of bone tissue growth. These properties, coupled with thermoplasticity and mechanical characteristics, make it a high-tech biomaterial.
