Структура И Физико-Химические Механизмы Взаимодействия Костной Ткани С Титановыми Имплантатами В Условиях Туберкулезного Остита

Abstract

The structure and physicochemical mechanisms of interaction of bone tissue with titanium implants in tuberculous osteitis have been studied by scanning electron microscopy, X-ray phase analysis, IR spectroscopy and thermal analysis methods. It has been found that the physiological regeneration of bone tissue is accompanied by growth of organic components, embrittlement of the mineral phase of the bone matrix, and its fine disintegration during the treatment of tuberculosis osteitis. The presence of titanium implants during a physiologically normal state contributes to the activation of apatite phase synthesis in the regenerating bone. The main mechanism of implantation osteogenesis in tuberculous osteitis is the formation of the inorganic phase of hydroxyapatite mainly in the areas of destruction of the titanium alloy.
