The ossification of wrist bones in children of tajikistan

One of the important tasks of modern anatomy is the study of the age dynamics of morphological features of the human body. Different timing of the appearance of ossification centers may be due to certain interethnic differences, and the age of ossification of individual bones may differ in representatives of different ethno-geographic populations. The formation of criteria for assessing the growth processes of children should be based on data developed in the study of a particular population, taking into account the specifics of the ethnic composition of the population. The purpose of the study is to establish the features in the timing of the appearance of ossification points in the bones of the wrist in children in Tajikistan. The material for the study was 209 radiographs of the right hand of children and adolescents of both sexes aged 6-15 years, permanently residing in Tajikistan. The study revealed sex related differences in the process of ossification of the carpal bones. Ethnic features have been established in the age terms of the appearance of ossification centers in Tajik children. In children of Tajikistan, the latest age for the appearance of the ossification point in the lunate and triquetral bones has been established. On radiographs of girls in 100% of cases, the ossification point of the triquetral bone was observed at the age of 6 years, in the lunate and trapezoid bones at 7 years, in the navicular and trapezoid bones at 8 years. In boys, only at the age of 8 years, in 100% of cases, ossification points were visualized in all the bones of the wrist, except for the pisiform bone. The results of the study differ from the data obtained for children living in St. Petersburg and the North-Western region, as well as Saudi Arabia. Thus, the timing of the appearance of ossification points in the bones of the wrist of Tajik children has ethnic characteristics that may be associated with the influence of hereditary factors, which should be taken into account to assess the physical development of children during their migration to other countries and regions. The established latest dates for the appearance of centers of ossification in the bones of the wrist, if necessary, can be used to clarify the chronological age of Tajik children.
