[The development of the vertebral articulations in the fetal period].
In this paper the thoracic tract of fetal rachis aging between 9 and 19 weeks has been investigated. The study has been carried out with histological and radiological techniques. The histological examination of these samples reveals that the articular processes are completely formed at week 12, in this period it is also evident a primitive joints between the articular processes. Nevertheless the joint is completely formed only at week 19, when the fibrous capsula and the synovial cavity are well formed. These data are confirmed by the sectional radiography.
