[Radiographic evaluation of the hip in children. Proposal for standardizing findings].

Considering that the complexity of the numerous X-ray techniques proposed for study of the child hip are ill fitted to standardization of the investigation, straightforward frontal and axial projections are proposed for this purpose. These are carried out with a special technique to enable subsequent controls to be reproduced and so as to obtain, with the aid of precise measurements, a complete morphological picture of the joint in question. Possibilities of error and exposure to ionizing radiations are cut to the minimum. These ideas are all the more indispensable today in the presence of problems of selecting children by peripheral units and centres responsible for specific conditions, even though techniques of maximum simplicity and safety are used.
