The use of ultrasound scanning in the management of developmental disorders of the hip

Ultrasound was used, together with clinical examination, to help in the diagnosis and to evaluate the treatment of 48 babies with congenital disorders of the hip. The femoral head, and its relation to the acetabulum, can be demonstrated before it becomes visible on radiographs. Ionising radiation is avoided. Ultrasound scanning can be used to visualise the repositioning of the femoral head. It is also possible to examine babies on an abduction frame.
