[Potentials of the echographic documentation of hip epiphysiolysis]

The results are presented of a study on patients affected by hip joint epiphyseolysis. The sonographic examination was performed using a unit with a linear 5 MHz probe; oblique scans were obtained, along the axis of the neck of the femur. Typical US findings are described, namely a small step corresponding to a positioning defect of the cartilage between head and neck of the femur and dilatation of the infracapsular space due to the presence of intra-articular fluid.
