The authors measured the superior vena cava in the newborn by radiologic, anatomic and histologic methods and analysed the correlations between cross-sectional area and the biometric data. This method makes it possible to select the size of catheter for parenteral nutrition via the superior vena cava in relation to body-weight.

In order to define the technical modalities of the so-called transgluteal approach to the hip, the authors studied the structure and topography of the anatomic features encountered in this approach. The gluteus medius, gluteus minimus and vastus lateralis muscles are anatomically continuous by way of their tendinous fibers. ⋯ The caudal neurovascular trunk of the space between the gluteus medius and vastus lateralis is situated at a distance of 3 to 5 cm from the greater trochanter. The practical surgical implications are discussed, particularly as regards the methods of dissecting the anterior margin of the transgluteal incision, exposure of the capsule and preservation of the neurovascular pedicle, with reference to concepts published previously in studies elsewhere.
