Early diagnosis of congenital dislocation of the hip. First experimental examinations and results.

Preliminary trials with computer tomography in the diagnosis and evaluation of dysplastic hips have brought the following results: (1) The figures closely resemble the x-rays and are as easily read, however, the amount of radiation is much less. (2) Cartilage form and borders are visible so that diagnosis is possible prior to the age of 3 months. (3) Since soft tissue contours are visible, it is expected that arthrography would be superfluous, thereby resulting not only in less x-ray exposure for the small child or infant but also reduction in risk due to anaesthesia and of joint puncture with its risk of infection (though minimal). As to whether or not the question of cost will be so positively answered, it is not yet clear. Further evaluation of this technique is presently being undertaken.
