Состояние прямых мышц живота на фоне фенотипических проявлений дисплазии соединительной ткани и их возрастных изменений

The purpose of this study is to assess the condition of the muscle tissue of the rectus abdominis muscles, taking into account the phenotypic manifestations of connective tissue dysplasia, to determine the age-related changes in the muscles.In the group of young men with hypermobility there is a reduced echogenicity of the muscle tissue, which can be interpreted as hypotrophy of the rectus abdominis muscles. The positive correlation between the muscle echogenicity index and the thickness of the white line of the abdomen is more pronounced in men with hypermobility of the joints (r = 0.56, p = 0.03), which indicates a connection between connective tissue dysplasia and muscle changes. The revealed decrease in the thickness of the white line of the abdomen with an increase in its width in combination with a decrease in the echogenicity of the rectus abdominis muscle may determine higher risks of hernia formation in the white line of the abdomen with increasing load on the muscular aponeurotic carcass.
