[Anatomic characteristics of the pelvis in children].
Growth characterizes the pelvic modifications until adult maturity is reached. Recollection of pelvic ossification is done insisting upon the primary ossification points, the triradiate cotyloid cartilage and the secondary ossification points. The socket's neonatal particular morphology with it's cartilaginous roof and it's fibrocartilaginous acetabular labrum finds it's application in ultrasonography. Bone modifications which occur permanently during growth result in increase of pelvic volume and in modifications of the physical mechanical resistance characteristics so that there are differences between children and adult fractures. Ligamental hyperlaxity and numerous cartilaginous structures are also accountable for these differences. About visceral concern, the main characteristic apart from genital modifications is the apparent migration of the bladder from the neonatal abdominal position down to the adult backward pubic position. Bladder capacity variations have been studied. The male urethra anatomy is recalled from which the different surgical procedures are deduced. The main vasculo nervous axes orientations are described allowing the comprehension of CT scan images. In fact the horizontal plan given by the modern imagery is sometimes difficult to study. An apprentice ship schedule is given following the bone, vasculo-nervous and visceral identification.
