[Echographic anatomy of the newborn hip and high-resolution equipment: internal capsular stria and perichondrial gap].
The use of high-resolution US equipment in the examination of the newborn hip allowed the evaluation of a thin echogenic stripe (the internal capsular stripe), which defines laterally the acetabular hyaline cartilage. By means of an anatomo-histological preparation the echogenic stripe can be related to either the capsular circular fibres or the interface between the latter and the hyaline cartilage. The internal capsular stripe, together with the echogenic synovial stripe, precisely delimit the whole acetabular hyaline cartilage. Furthermore, in many babies high-resolution US sometimes fails to demonstrate Graf's "perichondral gap", so that an accurate anatomic knowledge of the hip becomes necessary in the evaluation of acetabular labrum.
